Hereditary Motor and Sensory Neuropathy with Deafness, Intellectual Disability and Absent Sensory Large Myelinated Fibres

Hereditary motor and sensory neuropathy with deafness, intellectual disability and absent sensory large myelinated fibres is a very rare inherited nerve disease. It affects the long nerves that carry signals to the muscles (motor nerves) and from the skin to the brain (sensory nerves). It also affects the inner ear, so hearing is poor from birth or early life, and it affects brain development, so learning and understanding are delayed. In nerve biopsy, doctors see that the big, thick, myelin-covered sensory nerve fibres are missing, while small fibres may still be present. Because the problem is present from birth and comes from a genetic change, the weakness and disability usually start in childhood and slowly get worse over time.

Hereditary motor and sensory neuropathy with deafness, intellectual disability and absent sensory large myelinated fibres is a very rare type of Charcot-Marie-Tooth (CMT)–like disease. It is a genetic (usually inherited) nerve disease that mostly affects the long nerves of the arms and legs (peripheral nerves), and also the hearing nerve and parts of the brain that help with learning and speech. Children usually develop weak and thin muscles in the feet and hands, have trouble walking, are born with or develop permanent hearing loss, and have mild to moderate learning problems. Nerve biopsy shows that the large myelinated nerve fibres that normally carry fast signals are almost completely missing.PubMed+3Orpha.net+3Kisho+3

This condition belongs to the Charcot-Marie-Tooth (CMT) group of diseases, which are also called hereditary motor and sensory neuropathies. In this special form, there is a demyelinating neuropathy, which means the myelin (the “insulation” around the nerve) is damaged or not formed well. This slows down nerve signals and makes muscles weak and wasted in the hands and feet. The disease usually starts early in life, the weakness gets worse slowly, and children can also have problems with balance and walking. Monarch Initiative+2Orpha.net+2

In this syndrome, hearing loss is usually “sensorineural,” which means the problem is in the inner ear or the hearing nerve, not in the outer or middle ear. The deafness is often present from birth, so the child may not develop normal speech. Intellectual disability is often mild to moderate, so the child may be slower to sit, walk, speak, learn at school, and take care of themselves. These three main features – neuropathy, deafness, and intellectual disability – together make this disorder stand out from more common types of CMT. JNS Journal+3Orpha.net+3Global Genes+3

When doctors look at a small piece of nerve under the microscope (usually the sural nerve near the ankle), they see that large myelinated sensory fibres are absent or almost absent. Small myelinated and unmyelinated fibres may still be present, and there is usually no major axon loss. This special pattern helps doctors recognise this rare syndrome and separates it from other forms of hereditary neuropathy. Springer+4PubMed+4ScienceDirect+4

Another names

This disorder has several other names in the medical literature and rare disease databases. All of them describe the same basic condition: a hereditary neuropathy with deafness and intellectual disability and absent large sensory myelinated fibres. Kisho+4Genetic Disease Info Center+4National Organization for Rare Disorders+4

Some other names include:

1. Charcot-Marie-Tooth disease–deafness–intellectual disability syndrome. Genetic Disease Info Center+2Orpha.net+2

2. CMT-deafness-intellectual disability syndrome. Genetic Disease Info Center+2Kisho+2

3. Hereditary motor and sensory neuropathy with deafness, intellectual disability and absent sensory large myelinated fibres (British spelling “fibres”). National Organization for Rare Disorders+2Athena+2

4. Neuropathy, hereditary motor and sensory, with deafness, intellectual disability, and absent sensory large myelinated fibres. National Organization for Rare Disorders+2Kisho+2

5. Hereditary motor and sensory neuropathy with deafness, mental retardation and absence of large myelinated fibres (older wording in early reports). Springer+3PubMed+3ScienceDirect+3

Rare-disease databases and some coding systems may list several slight wording changes of these names, but they all refer to the same rare demyelinating hereditary neuropathy with these characteristic features. Kisho+3Genetic Disease Info Center+3Monarch Initiative+3

Types

Doctors do not yet have formally agreed clinical “types” like type 1, type 2, etc., just for this small syndrome. It is usually described as one rare demyelinating hereditary motor and sensory neuropathy with deafness and intellectual disability. Monarch Initiative+2Orpha.net+2

However, we can think about types in a practical way when looking at patients:

Some people can be grouped by age of onset. In most reports, symptoms begin in early childhood, often before school age, and hearing loss is present from birth. In theory, there could be milder or later-onset cases that are not recognised, but published reports show early onset as the usual pattern. Global Genes+3PubMed+3JNS Journal+3

Another possible way to think about types is by severity of neuropathy. Some children may walk independently for many years with only mild foot deformities and slight weakness, while others may have more severe weakness, need walking aids earlier, or have more marked muscle wasting in the legs and hands. This idea of “milder” and “more severe” forms is seen in other CMT subtypes as well. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

A third way is by genetic background. Similar combinations of hereditary neuropathy and deafness have been described in distinct genetic settings, such as hereditary motor and sensory neuropathy-Lom and other Roma-associated neuropathies, though those do not always include intellectual disability or the same nerve-biopsy picture. This suggests that related but genetically different disorders can give overlapping clinical pictures. PM&R KnowledgeNow+3OUP Academic+3Nature+3

Because the condition is extremely rare and only a few families have been described, more research is needed before doctors can confidently divide this syndrome into clear genetic or clinical subtypes. Springer+3PubMed+3ScienceDirect+3

Causes

1. Inherited genetic mutation – The main cause is a change (mutation) in a gene that controls how peripheral nerves and their myelin sheaths develop and survive. The exact gene for this exact syndrome is not always identified, but in related hereditary motor and sensory neuropathies, mutations in genes such as PMP22, MPZ, GJB1, EGR2, and others are known to disturb myelin and axons. PM&R KnowledgeNow+2JAMA Network+2

2. Autosomal recessive inheritance – In many rare hereditary neuropathies with early onset and severe involvement, the inheritance pattern is autosomal recessive. This means the child receives one faulty gene copy from each parent, who are usually healthy carriers. A similar pattern is suspected in families described with this syndrome. PM&R KnowledgeNow+3Monarch Initiative+3Orpha.net+3

3. Demyelination of peripheral nerves – The genetic change leads to poor or unstable formation of myelin, the insulating layer around nerves. When myelin is thin, missing, or broken, nerve conduction slows down and becomes blocked, producing weakness and loss of deep tendon reflexes, as seen in this condition. Monarch Initiative+2Orpha.net+2

4. Loss of large sensory myelinated fibres – A key cause of the clinical picture is the absence of large myelinated sensory fibres in nerve biopsy. These fibres normally carry vibration, position sense, and fine touch. When they are missing, sensory signalling is severely affected at a microscopic level, even if bedside sensory testing looks relatively preserved at first. Springer+4PubMed+4ScienceDirect+4

5. Abnormal development of hearing pathways – The gene change also affects structures in the inner ear or the auditory nerve, leading to congenital sensorineural deafness. The hearing loss is not due to infections or noise trauma but is present from early life because of abnormal nerve or hair cell function. Orpha.net+2PM&R KnowledgeNow+2

6. Impact on brain development – Intellectual disability suggests that the genetic defect also affects brain development. This may involve subtle changes in brain structure or function that lead to delayed language, learning difficulties, and problems with complex tasks. Orpha.net+2Global Genes+2

7. Axonal dysfunction in motor nerves – Even when myelin is the primary target, the underlying axons (nerve fibres) can also become damaged over time. This axonal dysfunction leads to progressive muscle wasting and weakness, especially in the distal muscles of the feet and hands. PM&R KnowledgeNow+2JAMA Network+2

8. Defective nerve repair mechanisms – Healthy nerves can repair myelin damage to some extent. In hereditary demyelinating neuropathies, repair mechanisms often fail because the underlying gene defect is always present. This long-term failure to repair myelin contributes to the chronic progressive course. PM&R KnowledgeNow+1

9. Genetic background and modifiers – Other genes in the patient’s genome can make the main mutation’s effect milder or more severe. These “modifier genes” might help explain why some family members with the same mutation are more disabled than others. PM&R KnowledgeNow+2JAMA Network+2

10. Consanguinity (parents related by blood) – In populations where marriage between relatives is more common, autosomal recessive disorders like this one may appear more often, because both parents might carry the same rare mutation. Several hereditary neuropathies with deafness have been reported in such settings. OUP Academic+2Nature+2

11. Ethnic founder effects – In some ethnic groups, a mutation may start in one ancestor and then spread through the group over generations (founder effect). This has been shown for hereditary motor and sensory neuropathy-Lom in Roma populations, and similar effects may exist for other combined neuropathy–deafness syndromes. OUP Academic+2Nature+2

12. Myelin protein pathway disruption – Many CMT-related genes encode proteins of the myelin sheath or its regulation. When these proteins are faulty, Schwann cells (myelin-forming cells) cannot maintain normal myelin, leading to the demyelinating neuropathy seen in this syndrome. PM&R KnowledgeNow+2JAMA Network+2

13. Abnormal neuron–glia signalling – The communication between nerve cells (neurons) and glial cells that support them is important for healthy nerve function. Gene defects can disturb this signalling, especially in long peripheral nerves, contributing to neuropathy. PM&R KnowledgeNow+1

14. Long nerve length and vulnerability – The longest nerves, such as those going to the feet, are more vulnerable to damage. Because of their length, even modest problems in myelin or axon function can cause weakness and deformity in the feet first, as seen in many hereditary neuropathies. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

15. Chronic secondary changes in muscles – Over time, the ongoing nerve damage causes muscles to waste (atrophy). This muscle atrophy and imbalance around joints then cause foot deformities like high arches or hammer toes, which are common in CMT-like disorders. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

16. Impact of growth and development – As the child grows, nerves have to keep up with increased body size. In a genetic neuropathy, the damaged nerves cannot fully adapt to this growth, so weakness and gait problems often become more obvious during growth spurts. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

17. Limited nerve regeneration capacity – Unlike some other tissues, human peripheral nerves regenerate slowly and incompletely. In hereditary neuropathies, the constant background damage from the gene defect outpaces the limited regeneration, making the condition long-lasting and progressive. PM&R KnowledgeNow+1

18. Lack of protective treatments – At present, there is no specific cure that can correct the underlying genetic cause. At best, treatments are supportive, so the natural course driven by the genetic defect continues throughout life, contributing to disability. PM&R KnowledgeNow+2Monarch Initiative+2

19. Possible shared pathways with other CMT forms – Because this syndrome sits within the broader CMT spectrum, it is likely that some of the same molecular pathways (such as those involving myelin protein 22 or myelin protein zero) are disturbed, even if the precise mutation is not always known. This shared biology is a deeper cause of the similar clinical features. PM&R KnowledgeNow+2JAMA Network+2

20. Environmental factors shaping expression – While the main cause is genetic, environmental factors such as nutrition, co-existing illnesses, physical activity level, and access to therapy can influence how severe the disability becomes, even though they do not cause the disease in the first place. PM&R KnowledgeNow+1

Symptoms

1. Distal muscle weakness – The earliest and main symptom is weakness in the muscles farthest from the body, especially in the feet and lower legs. Children may have trouble running, hopping, or climbing stairs, and they may tire easily. Over time, weakness can also affect the hands, making fine tasks like buttoning or writing harder. Monarch Initiative+2Orpha.net+2

2. Muscle wasting (atrophy) – Because the nerves no longer activate the muscles normally, the muscles in the calves, feet, and sometimes hands become thin and wasted. The legs can look like “stork legs,” with thin calves, which is classic for demyelinating hereditary neuropathies. Monarch Initiative+2PM&R KnowledgeNow+2

3. Gait problems and frequent falls – Children may walk with a high-stepping gait because they cannot lift the front of the foot well (foot drop). They may trip on small obstacles and fall more often than other children. Balance may be poor, especially in the dark or on uneven ground. Monarch Initiative+2Orpha.net+2

4. Foot deformities – Over years, muscle imbalance around the ankle and foot leads to structural deformities. The arches become very high (pes cavus), toes may claw or hammer, and ankles may turn inward or outward. These deformities can cause pain and make shoe fitting difficult. Monarch Initiative+2PM&R KnowledgeNow+2

5. Reduced or absent reflexes – In neurological examination, tendon reflexes (like the knee-jerk or ankle reflex) are often weak or absent. This is a typical sign of peripheral neuropathy and results from slow or blocked conduction in reflex pathways. Monarch Initiative+2PM&R KnowledgeNow+2

6. Hearing loss (sensorineural deafness) – A key symptom is congenital or very early-onset hearing loss caused by a problem in the inner ear or hearing nerve. The child may not respond to sounds, may not startle to loud noises, or may not follow spoken instructions. Without early hearing support, speech often does not develop normally. Orpha.net+2Global Genes+2

7. Delayed speech and language – Because hearing is poor, and possibly because brain development is affected, children often speak late and may have limited vocabulary and simple sentence structure. They may rely more on gestures or visual cues to communicate. Orpha.net+2Global Genes+2

8. Mild to moderate intellectual disability – Most reported patients have mild to moderate intellectual disability, meaning that they can learn many skills but at a slower pace than peers. They may struggle with reading, maths, problem-solving, and independent daily living, and they usually need extra support at school. Orpha.net+2Global Genes+2

9. Delayed motor milestones – Because of weakness and neuropathy, children may sit, stand, and walk later than usual. They may need physiotherapy and special support to reach these milestones, and the quality of movement may stay clumsy. Monarch Initiative+2Orpha.net+2

10. Sensory changes – Bedside testing may show mild or sometimes surprisingly little sensory loss, but children can have subtle problems with feeling vibration or joint position. In some cases, they may be less aware of injuries to the feet or may feel tingling or burning sensations. Monarch Initiative+2PM&R KnowledgeNow+2

11. Fatigue and reduced endurance – Children and adults with this neuropathy often feel tired quickly when walking or using their hands. Because muscles are weaker and nerves work less efficiently, daily tasks require more effort and cause fatigue. PM&R KnowledgeNow+2Semantic Scholar+2

12. Contractures and joint stiffness – When muscles are weak and imbalanced, joints may gradually stiffen and lose full range of movement. Ankles and toes are most often affected, and without stretching and physiotherapy, permanent contractures can form. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

13. Psychosocial difficulties – Deafness, intellectual disability, and physical disability together can cause social isolation, low self-confidence, and emotional problems. Children may struggle to join in with peers, and families may need psychological and social support. Orpha.net+2Global Genes+2

14. Possible scoliosis and skeletal problems – As in other CMT forms, spinal curvature (scoliosis) and hip problems may appear over time because of muscle imbalance and weakness. These skeletal issues can further affect posture and walking. PM&R KnowledgeNow+2Monarch Initiative+2

15. Progressive course across life – The symptoms usually progress slowly over many years. Weakness and deformity increase, and walking may become more difficult with age. However, many patients can live into adulthood, especially with good supportive care such as physiotherapy, orthoses, and hearing rehabilitation. Monarch Initiative+2Orpha.net+2

Diagnostic tests

Because this is a very rare disease, diagnosis needs a step-by-step approach. Doctors try to confirm that there is a hereditary demyelinating neuropathy, and then they look for the special combination of deafness, intellectual disability, and absent large myelinated sensory fibres. PubMed+3Monarch Initiative+3Orpha.net+3

Physical exam tests

1. Full neurological examination – The neurologist or paediatric neurologist checks muscle strength, tone, reflexes, sensation, and coordination. Weak distal muscles, thin calves, absent ankle reflexes, and mild sensory changes point to a length-dependent peripheral neuropathy that fits with hereditary motor and sensory neuropathy. Monarch Initiative+2PM&R KnowledgeNow+2

2. Gait and posture assessment – The doctor watches the child walk, run, and stand. A high-stepping “steppage gait,” foot drop, imbalance, and difficulty walking on heels or toes support the diagnosis of a motor neuropathy affecting the lower limbs. Monarch Initiative+2PM&R KnowledgeNow+2

3. Musculoskeletal and foot examination – The feet, ankles, spine, and hands are checked for deformities such as high arches, hammer toes, scoliosis, or hand muscle wasting. These structural signs reflect long-standing neuropathy and help to distinguish hereditary neuropathies from short-lived acquired causes. Monarch Initiative+2PM&R KnowledgeNow+2

4. General physical and developmental exam – Height, weight, head size, and pubertal development are measured, and overall health is checked. The doctor also looks for features that might suggest another syndrome or metabolic disease, helping to narrow the diagnosis to this specific neuropathy syndrome rather than something else. PM&R KnowledgeNow+2Monarch Initiative+2

Manual bedside tests

5. Manual muscle testing – The examiner presses against the child’s arms and legs in different directions to grade strength on a simple scale. This bedside test maps which muscles are weak, usually showing more weakness in the distal muscles than in the proximal ones, fitting a hereditary motor neuropathy pattern. PM&R KnowledgeNow+2Monarch Initiative+2

6. Reflex testing with a tendon hammer – Reflexes at the knees, ankles, elbows, and wrists are tapped with a hammer. Reduced or absent reflexes, especially at the ankles, are typical of peripheral neuropathy and help separate neuropathic weakness from muscle or brain diseases. Monarch Initiative+2PM&R KnowledgeNow+2

7. Sensory bedside tests (light touch, vibration, position sense) – Using cotton, tuning forks, and passive joint movement, the examiner checks if the child can feel light touch, vibration, and the position of toes and fingers. In this syndrome, large fibre sensory function may be reduced, even if the child does not complain clearly, matching the biopsy finding of absent large myelinated fibres. PubMed+3Monarch Initiative+3PM&R KnowledgeNow+3

8. Romberg and balance tests – The child is asked to stand with feet together and then with eyes closed (Romberg test), and to walk heel-to-toe. Increased swaying or loss of balance indicates impaired position sense or weakness, supporting the diagnosis of a large-fibre neuropathy. PM&R KnowledgeNow+2Monarch Initiative+2

9. Coordination tests (finger-to-nose, heel-to-shin) – These bedside tests check whether the child can smoothly guide their limbs to a target. In hereditary neuropathy, coordination may be clumsy mainly because of weakness and sensory loss, but basic brain coordination pathways are usually preserved, helping to differentiate from cerebellar disease. PM&R KnowledgeNow+2Monarch Initiative+2

10. Bedside hearing screening (whispered voice, tuning fork tests) – Simple office tests like whispering behind the child or using tuning forks (Rinne and Weber tests) can show that the hearing loss is sensorineural. These quick tests guide the doctor to order more detailed audiology studies. Orpha.net+2Journal of Pediatric Surgery+2

Lab and pathological tests

11. Basic blood tests (metabolic and nutritional screen) – Blood tests for glucose, thyroid function, vitamin B12, folate, and other markers are done to rule out common acquired causes of neuropathy, such as diabetes or vitamin deficiency. Normal results support a hereditary cause rather than a secondary neuropathy. PM&R KnowledgeNow+2Semantic Scholar+2

12. Genetic testing for hereditary neuropathy and deafness – Modern genetic panels or exome sequencing can search for mutations in many CMT and deafness genes at once. Finding a disease-causing mutation confirms the inherited nature of the neuropathy and may eventually link individual families with this specific syndrome. PM&R KnowledgeNow+2JAMA Network+2

13. Nerve biopsy (usually sural nerve) – A small piece of sensory nerve from the leg is removed and examined under the microscope and by electron microscopy. In this syndrome, nerve biopsy shows absence or severe reduction of large myelinated sensory fibres, with relatively preserved small fibres, a key diagnostic hallmark that supports the specific diagnosis. Springer+4PubMed+4ScienceDirect+4

14. Pathology stains and morphometry – Special stains and measurements on the biopsy sample help to count fibre types and assess myelin thickness. These measurements document the lack of large myelinated fibres and the demyelinating pattern, giving objective evidence for the disease and helping in research. Wiley Online Library+3PubMed+3ScienceDirect+3

15. Cerebrospinal fluid (CSF) examination (when needed) – A lumbar puncture is sometimes done to examine the fluid around the brain and spinal cord. In hereditary neuropathies, CSF protein may be normal or only mildly raised, helping to distinguish them from acquired inflammatory neuropathies like Guillain-Barré syndrome, which show much higher protein. PM&R KnowledgeNow+2Wikipedia+2

Electrodiagnostic tests

16. Nerve conduction studies (NCS) – Small electrical pulses are applied to nerves, and responses are recorded. In this syndrome, motor and sensory conduction velocities are markedly slowed, and sensory responses may be absent, showing a demyelinating neuropathy. This pattern supports the diagnosis and guides further testing. Semantic Scholar+3PubMed+3Monarch Initiative+3

17. Electromyography (EMG) – A fine needle electrode is inserted into muscles to record electrical activity at rest and during contraction. EMG in hereditary neuropathy usually shows chronic neurogenic changes, such as large motor units and reduced recruitment, confirming that the problem is in the nerves, not primarily in the muscles. PM&R KnowledgeNow+2Monarch Initiative+2

18. Auditory brainstem response (ABR) / brainstem auditory evoked potentials – This test records brain responses to clicking sounds using electrodes on the scalp. In this syndrome, ABR often shows abnormal or absent waves, confirming sensorineural deafness and showing that the hearing pathway from ear to brainstem is not working normally. Orpha.net+2Journal of Pediatric Surgery+2

Imaging tests

19. MRI of brain and inner ear (when indicated) – Magnetic resonance imaging (MRI) of the brain and inner ear can help rule out other causes of deafness or neurological problems, such as tumours or malformations. In many hereditary neuropathies, MRI is normal, but it is useful to exclude other diagnoses when symptoms are complex. PM&R KnowledgeNow+2Journal of Pediatric Surgery+2

20. Spine and nerve imaging (MRI or ultrasound) – MRI of the spine or ultrasound of peripheral nerves is sometimes used to look for thickened nerves or other structural changes seen in some demyelinating neuropathies. While not specific, these imaging tests can provide additional support for the diagnosis and help to rule out compressive or inflammatory causes. PM&R KnowledgeNow+2Monarch Initiative+2

Non-pharmacological treatments (therapies and others)

I will list 20 important non-drug treatments. In real life, a team chooses the most useful ones for each child.

1. Physiotherapy (physical therapy)
   A physiotherapist teaches stretching, strengthening and balance exercises. The purpose is to keep joints flexible, slow down contractures, and maintain muscle power so that walking and hand use stay as good as possible. The main mechanism is repeated safe movement that protects muscles from wasting and joints from becoming stiff. Exercises are kept simple and fun so that a child can repeat them every day with help from family.

2. Occupational therapy
   An occupational therapist helps the child learn daily skills such as dressing, writing, eating, and using tools. The goal is independence in everyday life. The therapist may suggest special grips for pens, adapted cutlery, or modified keyboards. The mechanism is “task-specific training”: practicing real-life activities again and again, sometimes with simple devices, to build new habits and pathways in the brain and remaining nerves.

3. Speech and language therapy
   Many patients have delayed speech from deafness and intellectual disability. Speech therapists teach lip reading, basic spoken words if possible, and alternative communication systems. The purpose is to help the child share needs, feelings and thoughts. The mechanism is slow step-by-step practice of sounds, words, pictures and gestures, repeated many times so the brain can learn new communication patterns even if hearing is poor.

4. Audiology care and hearing aids
   An audiologist tests hearing regularly and fits hearing aids if the inner ear and nerve can still carry some sound. The goal is to give the brain as much sound information as possible to support language and safety (for example, hearing alarms or traffic). The mechanism is amplification: microphones pick up sound, make it louder and clearer, and send it into the ear canal, where remaining hair cells and nerves pass the signal to the brain.Orpha.net+1

5. Cochlear implant rehabilitation
   If deafness is severe and a cochlear implant is done, the child needs long-term training afterwards. Therapists help the child understand the new “electronic” sound. The purpose is to build useful hearing and improve language and school skills. The mechanism is brain plasticity: the implant stimulates the hearing nerve with electrical signals, and the brain slowly learns to treat these patterns as sound and speech.

6. Orthotic devices (braces and splints)
   Ankle–foot orthoses (AFOs), wrist splints, or finger splints can support weak muscles, reduce foot drop and prevent deformities such as high arches or claw toes. The aim is safer walking and better hand function. The mechanism is simple mechanical support: plastic or carbon braces hold joints in a better position so that small remaining muscles can work more effectively and energy use is lower.

7. Mobility aids (walkers, canes, wheelchairs)
   When balance and leg strength are low, a walker, rollator, cane or wheelchair can greatly improve safety and independence. The purpose is not to “give up walking” but to prevent falls and allow the child to join school and family activities. The mechanism is redistribution of weight and support so that the body does not rely only on weak distal muscles and damaged nerves.

8. Respiratory physiotherapy (if needed)
   Some neuropathies later affect breathing muscles or cause weak cough. Chest physiotherapy, breathing exercises and devices that help clear mucus reduce the risk of chest infections. The purpose is to keep lungs as healthy as possible. The mechanism is improving lung expansion and cough force so that secretions are moved out of the airways.

9. Special education and learning support
   Because mild to moderate intellectual disability is part of this syndrome, early and continued educational support is essential. The purpose is to help the child reach the best possible level in reading, writing, counting and life skills. The mechanism is “individualized education plans”: tasks are broken into very small steps, repeated, and matched to the child’s speed of learning.Orpha.net+1

10. Behavioural therapy
    Some children may be impulsive, frustrated or anxious because of communication problems and disability. Behavioural therapists teach families practical strategies such as reward systems, clear routines and calm responses to difficult behaviour. The goal is a more predictable and peaceful daily life. The mechanism is changing patterns of behaviour through positive reinforcement and consistent boundaries.

11. Psychological support for child and family
    Living with a rare condition can be stressful and lonely. Psychologists or counsellors give a safe space to talk about fear, anger or sadness. The purpose is to protect mental health of both child and carers. The mechanism is emotional support, coping skills, and sometimes simple cognitive-behavioural techniques to manage anxiety and low mood.

12. Social work and disability benefits support
    A social worker helps the family access school support, government disability benefits, transport aid and respite care. The aim is to reduce financial and practical stress. The mechanism is guidance through local systems and paperwork, and linking families to community resources.

13. Genetic counselling
    Because this is a hereditary neuropathy, parents and older children should have genetic counselling. The purpose is to explain inheritance (often autosomal recessive or X-linked), chance of recurrence in future pregnancies, and options such as carrier testing. The mechanism is detailed family history, genetic testing if available, and clear education using simple words.NCBI+1

14. Nutritional counselling and weight management
    Weak muscles and less movement can lead to weight gain, which makes walking and transfers harder. A dietitian helps plan balanced meals with enough protein, vitamins and minerals but not too many calories. The mechanism is adjusting portion sizes and food choices so that weight stays in a healthy range while supporting nerve and muscle health.

15. Fall-prevention and home safety training
    Therapists can check the home and suggest changes such as removing loose rugs, adding grab rails, using non-slip mats and improving lighting. The purpose is to lower the risk of fractures and head injuries from falls. The mechanism is reducing environmental hazards and teaching safe ways to move, turn and transfer.

16. Pain self-management programmes
    Even though this form of neuropathy may have less sensory pain than other types, some patients still develop aching, cramps or musculoskeletal pain. Education about pacing, gentle stretching, relaxation, heat/cold packs and posture can reduce discomfort. The mechanism is reducing strain on joints and changing how the brain responds to chronic pain signals.

17. Sleep hygiene and fatigue management
    Fatigue is common in chronic neurological diseases. Setting regular sleep times, limiting screen use before bed, keeping the bedroom dark and quiet, and planning rests during the day can help. The purpose is better energy for therapy and school. Mechanism: supporting the body’s natural sleep–wake rhythm and reducing overstimulation at night.

18. Communication training and sign language
    For children with profound deafness, learning sign language or picture-based communication systems is very important. The goal is to give a full language, not just a few gestures. The mechanism is using the child’s strong visual skills and repeated practice of signs so that language can develop even without sound.

19. Vocational training (for older teens and adults)
    As the child grows, occupational therapists and educators can help plan realistic job goals, such as computer-based work, crafts or office tasks. The aim is financial independence and self-esteem. Mechanism: matching abilities to job demands and teaching adaptive techniques and assistive technologies.

20. Patient and family support groups
    Rare disease groups (including CMT and rare neuropathy organisations) let families meet others with similar problems. The purpose is sharing experience, practical tips and emotional support. The mechanism is peer connection, which reduces isolation and gives role models of adults living a meaningful life with disability.Global Genes+1

Drug treatments

Important safety note: All medicines and doses must be chosen by a doctor who knows the patient. Never start or change a medicine without medical supervision. For this very rare hereditary neuropathy there is no specific disease-curing drug at present. Drugs are used only to control symptoms and complications.

Below are 20 important drug groups or examples. For safety, I will not give exact milligram doses; your doctor will set the dose, timing and schedule.

1. Gabapentin for neuropathic pain
   Gabapentin is a nerve pain and anti-seizure drug approved by the FDA for post-herpetic neuralgia and partial seizures.FDA Access Data+1 Doctors sometimes use it for chronic neuropathic pain in CMT-like diseases. It is usually taken one to three times daily. Purpose: lower burning or shooting pain and restless legs at night. Mechanism: modulates calcium channels in nerve cells and reduces abnormal excitability. Common side effects include sleepiness, dizziness and weight gain.

2. Pregabalin (Lyrica) for neuropathic pain
   Pregabalin is a newer drug in the same family as gabapentin. It is FDA-approved for several neuropathic pain conditions and as add-on therapy for seizures.NCBI+2FDA Access Data+2 It is usually given two or three times a day. Purpose: reduce nerve pain, improve sleep and sometimes lessen anxiety. Mechanism: binds to alpha-2-delta subunits of calcium channels, reducing release of excitatory neurotransmitters. Side effects: dizziness, drowsiness, swelling of legs, weight gain, and rarely breathing problems, especially with other sedative drugs.U.S. Food and Drug Administration

3. Duloxetine (Cymbalta) for pain and mood
   Duloxetine is an SNRI antidepressant approved for diabetic neuropathic pain, fibromyalgia, depression and anxiety.FDA Access Data+2NCBI+2 It is usually taken once daily. Purpose: treat low mood or anxiety and at the same time reduce chronic pain. Mechanism: increases serotonin and norepinephrine levels, which modulate pain pathways in the spinal cord and brain. Side effects: nausea, dry mouth, sweating, sleep changes, and sometimes increased blood pressure.

4. Tricyclic antidepressants (e.g., amitriptyline)
   Low-dose tricyclics are often used for neuropathic pain and sleep problems. They are usually taken at night. Purpose: improve sleep and reduce tingling pain. Mechanism: block reuptake of serotonin and norepinephrine and also block certain pain-related receptors. Side effects: dry mouth, constipation, blurred vision, drowsiness, and heart rhythm changes, so ECG monitoring is sometimes needed.

5. Baclofen for spasticity and cramps
   Some patients develop muscle stiffness or painful spasms. Baclofen is a muscle relaxant approved for spasticity.NCBI+2FDA Access Data+2 It is usually taken several times a day. Purpose: reduce stiffness and clonus so movement is easier. Mechanism: acts as a GABA-B receptor agonist in the spinal cord to reduce excitatory signals to muscles. Side effects: sleepiness, weakness, dizziness and, if stopped suddenly, withdrawal symptoms.

6. Tizanidine or other muscle relaxants
   Tizanidine is another drug for muscle spasticity. It acts on alpha-2 receptors in the spinal cord to reduce tone. Purpose: similar to baclofen, but with a different side-effect profile. Side effects: low blood pressure, dry mouth, drowsiness and abnormal liver tests; regular monitoring is needed.

7. Simple pain medicines (paracetamol/acetaminophen)
   For mild musculoskeletal pain or headache, doctors may use acetaminophen. It works on pain centres in the brain. Purpose: relieve everyday aches without strong side effects when used correctly. Mechanism: not completely understood; likely central COX inhibition. Overdose can severely damage the liver, so dosing must strictly follow medical advice.

8. NSAIDs (e.g., ibuprofen, naproxen)
   These medicines reduce inflammation and pain in joints and muscles if there are secondary problems such as contractures. Purpose: short-term relief of inflammatory pain. Mechanism: block cyclo-oxygenase enzymes and reduce prostaglandin production. Side effects: stomach irritation or ulcers, kidney strain and increased bleeding risk, so they must be used carefully, especially in children.

9. Anti-seizure medicines (e.g., levetiracetam, valproate)
   Some reported patients with similar neuropathy variants also had epilepsy.PubMed+1 If seizures occur, neurologists may use modern anti-seizure drugs. Purpose: prevent seizures and protect the brain. Mechanism: each drug has different actions on ion channels and neurotransmitters. Side effects vary but can include tiredness, behaviour changes or liver and blood problems, so monitoring is essential.

10. Melatonin or other sleep aids (short-term)
    When sleep is very disturbed even after good sleep hygiene, a doctor may prescribe melatonin or other short-term sleep aids. Purpose: improve sleep quality so the child can manage school and therapy. Mechanism: melatonin works on the body clock. Side effects are usually mild but long-term use in children should always be guided by a paediatrician.

11. Selective serotonin reuptake inhibitors (SSRIs) for anxiety/depression
    Living with a chronic disability increases the risk of anxiety and depression in both patients and carers. When counselling is not enough, SSRIs such as sertraline may be used. Purpose: lift mood and reduce anxiety. Mechanism: increase serotonin levels in brain synapses. Side effects: stomach upset, sleep changes, headache, and in youth a small increased risk of suicidal thoughts, so close follow-up is required.

12. Laxatives and bowel medicines
    Reduced mobility and medicines like baclofen can cause constipation. Doctors may prescribe stool softeners, osmotic laxatives or fibre supplements. Purpose: keep bowel movements regular and avoid abdominal pain. Mechanism: increase water in stools, stimulate gut movement or add bulk. Misuse may cause diarrhoea or electrolyte imbalance.

13. Vitamin B12 and folate when deficient
    If blood tests show low vitamin B12 or folate, supplements are needed because these vitamins are important for myelin and nerve function. Purpose: correct deficiency that may worsen neuropathy. Mechanism: provide cofactors for DNA synthesis and myelin formation. High doses without deficiency do not cure hereditary neuropathy and should not be used without testing.

14. Vitamin D and calcium if low bone density
    Because of reduced mobility, bones can become weak. Vitamin D and calcium supplements may be prescribed after testing. Purpose: support bone strength and reduce fracture risk. Mechanism: improve calcium absorption and bone mineralization. Too much can cause kidney stones and other problems, so medical monitoring is important.

15. Botulinum toxin injections for focal spasticity or contractures
    In selected cases with very tight muscles in one area, doctors may inject botulinum toxin into those muscles. Purpose: relax specific problematic muscles and improve positioning or ease of dressing. Mechanism: blocks acetylcholine release at the neuromuscular junction, briefly weakening the targeted muscle. Effect is temporary, and repeated injections may be needed.

16. Anticholinergic medicines for drooling (if present)
    In some children with neurological disability, excessive drooling can be a problem. Low-dose anticholinergic drugs or glycopyrrolate may be used. Purpose: reduce saliva and improve comfort, school participation and skin health. Mechanism: block muscarinic receptors in salivary glands. Side effects: dry mouth, constipation, blurred vision.

17. Proton-pump inhibitors or H2 blockers (if using NSAIDs long-term)
    If strong pain makes long-term NSAID use unavoidable, doctors may add stomach-protecting drugs. Purpose: lower risk of ulcers and bleeding. Mechanism: reduce gastric acid secretion. Overuse can affect nutrient absorption, so they are used only when really needed.

18. Treatment for associated endocrine or metabolic problems (if any)
    If evaluations find thyroid, glucose or other metabolic problems, those should be treated with standard medicines. Purpose: avoid extra stress on nerves and muscles. Mechanism: correcting hormones and metabolism to normal ranges.

19. Emergency medicines (e.g., rescue seizure medicine)
    Families may receive a rescue medicine for prolonged seizures, such as rectal diazepam or intranasal midazolam, depending on local practice. Purpose: stop a dangerous long seizure quickly while waiting for emergency care. Mechanism: GABA-A agonist that calms overactive brain cells. Must be used under strict medical instruction.

20. Medicines to treat intercurrent infections quickly
    Because mobility may be low and cough weak, lung infections can be serious. Doctors may sometimes give antibiotics or antivirals earlier than usual if pneumonia or serious infection is suspected. Purpose: prevent complications and hospitalisation. Mechanism: killing or blocking the growth of germs. Overuse of antibiotics can cause resistance and side effects, so they are not used for simple viruses.

Dietary molecular supplements

Evidence for supplements in this exact rare syndrome is very limited. Most advice is based on general nerve health. Always discuss supplements with a doctor to avoid unsafe combinations or high doses.

1. Omega-3 fatty acids (fish oil or algae oil)
   Omega-3 fats help build cell membranes and may have mild anti-inflammatory effects. They may support general brain and nerve health and heart health. A typical dose is a few hundred milligrams of EPA/DHA daily, but exact dose must be set by a doctor, especially in children. Mechanism: incorporated into neuronal membranes and may modify signalling and inflammation. Possible side effects: fishy after-taste, stomach upset, and slightly increased bleeding tendency at high doses.

2. Vitamin B12
   Vitamin B12 is essential for myelin and DNA synthesis. If tests show low levels, oral or injectable B12 is given in doses decided by a physician. Purpose: prevent preventable nerve damage on top of the hereditary problem. Mechanism: acts as a cofactor in methylation reactions needed for myelin production. High doses in normal B12 levels are usually safe but have not been proven to help hereditary neuropathies.

3. Folate (folic acid)
   Folate works with B12 in DNA and myelin synthesis. It may be supplemented if blood levels are low or if there is poor diet. Mechanism: provides one-carbon units for building DNA bases. Too much folic acid can hide B12 deficiency, so blood tests are important.

4. Thiamine (vitamin B1)
   Thiamine is important for energy metabolism in nerves. Severe deficiency causes neuropathy (beriberi). In patients with poor nutrition, replacing thiamine can protect remaining nerve function. Mechanism: cofactor in carbohydrate metabolism and nerve conduction. Doses must follow medical advice; very high doses are usually not needed.

5. Vitamin D
   Vitamin D supports bone and immune health. In children with low sun exposure or low blood levels, replacement can prevent rickets and fractures. Mechanism: helps absorb calcium from the gut and regulate bone remodelling. Excess can cause high calcium and kidney damage.

6. Alpha-lipoic acid
   Alpha-lipoic acid is an antioxidant used in some countries for diabetic neuropathy. It may help reduce oxidative stress in nerves, but strong data in hereditary neuropathies are lacking. Mechanism: participates in mitochondrial energy metabolism and scavenges reactive oxygen species. Doses and safety in children need careful specialist guidance.

7. Coenzyme Q10
   CoQ10 supports mitochondrial electron transport. In some mitochondrial diseases it can be helpful, and some neuropathy patients take it hoping to support energy production. Mechanism: improves electron flow in the respiratory chain. Side effects are usually mild (stomach upset), but evidence in this specific syndrome is minimal.

8. Magnesium (when low)
   If blood tests show low magnesium, replacement is important for nerve and muscle function. Mechanism: acts as a cofactor in many enzymes and helps stabilise nerve cell membranes. Too much magnesium can cause diarrhoea and, at very high levels, serious heart and breathing problems, so doctor-guided dosing is essential.

9. Antioxidant vitamins (vitamin C and E)
   Normal dietary amounts of vitamin C and E from fruit, vegetables, nuts and seeds support general health and may reduce oxidative stress. Very high supplement doses are not proven to help hereditary neuropathy and can sometimes be harmful, so food sources are preferred.

10. Balanced protein intake
    While not a “molecule in a pill”, adequate protein from food is vital to maintain muscle mass. Mechanism: provides amino acids needed to repair tissues and build enzymes. A dietitian can calculate safe amounts based on age, weight and kidney function.

Immunity-booster, regenerative and stem-cell-related drugs

For this specific hereditary neuropathy:

• There are currently no approved stem-cell drugs or gene therapies that have been proven safe and effective. Most work is still in laboratory or early clinical research.Orpha.net+1

• Any clinic offering “stem cell cures” for neuropathy outside a controlled trial should be treated with extreme caution. Many such treatments are unproven, very expensive and sometimes dangerous.

Instead, doctors focus on safer, evidence-based ways to protect health:

1. Routine vaccines (not really “drugs for the disease”, but vital)
   Standard childhood vaccines (and sometimes extra vaccines such as influenza and pneumonia vaccines) help prevent infections that could be more serious in someone with weak muscles and breathing. Mechanism: training the immune system to recognise specific germs.

2. Good nutrition and sleep as natural immunity support
   A healthy diet, enough sleep and regular gentle exercise support immune function better than most “immune booster” pills.

3. IVIG and other immune therapies – usually not used here
   Intravenous immunoglobulin (IVIG) is useful in immune-mediated neuropathies, but in hereditary neuropathies it usually does not help because the problem is in the genes and nerve structure, not in antibodies. It might be considered only if there is a second autoimmune condition, under specialist care.

4. Experimental nerve-growth or remyelination drugs
   Research in other neuropathies is exploring growth factors and remyelinating drugs, but these are not yet standard care and are only available in clinical trials. Families can ask specialists about ongoing trials, but should understand that benefits and risks are still being studied.

5. Bone-marrow or stem-cell transplantation (research stage)
   Some inherited nerve diseases are being studied with gene-corrected stem-cell treatments in animals, but not yet in routine human practice for this syndrome. At present, transplantation is not recommended outside carefully controlled trials.

6. Careful use of all medicines to avoid harming nerves
   Many chemotherapy agents, high-dose alcohol, and some other drugs can damage peripheral nerves. Doctors caring for this syndrome will try to avoid or minimise such medicines whenever possible. The best “regeneration help” for nerves is to prevent extra damage on top of the genetic problem.

Surgeries

1. Foot deformity correction (tendon transfer, osteotomy)
   Weakness in certain muscles can cause high-arched feet, claw toes and ankle instability. Orthopaedic surgeons may move tendons, cut and realign bones or lengthen tight tendons. Purpose: create a more plantigrade (flat) foot for safer standing and walking, and to fit braces better.

2. Contracture release surgeries
   Long-standing joint stiffness in ankles, knees, hips or fingers may need surgical release or lengthening of tight muscles and tendons. Purpose: improve range of motion, ease care (such as dressing) and make brace use possible.

3. Spinal surgery for scoliosis
   If scoliosis becomes severe and affects sitting balance, breathing or comfort, spinal fusion or other corrective surgery may be advised. Purpose: stabilise the spine, improve posture and protect lung function.

4. Cochlear implant surgery
   For profound sensorineural deafness, cochlear implantation may allow sound perception. Purpose: send electrical signals directly to the hearing nerve so the brain can learn to interpret them as sounds and speech. Best outcomes are in children implanted early and followed by intensive rehabilitation.

5. Orthopaedic stabilisation after fractures
   Because of falls and weak bones, fractures may occur. Surgery may be needed to fix broken bones so that mobility can be regained quickly and safely.

Prevention and risk reduction

1. Genetic counselling for parents and older family members before future pregnancies.

2. Early hearing screening and neurologic evaluation for siblings who might also carry the condition.

3. Regular follow-up with neurology, audiology and rehabilitation teams to detect problems early.

4. Daily home exercise and stretching routines to slow contractures and maintain strength.

5. Weight control through balanced diet and activity to reduce strain on weak muscles and joints.

6. Home safety measures (grab bars, non-slip surfaces, good lighting) to prevent falls.

7. Up-to-date vaccinations and quick treatment of infections to protect lungs and general health.

8. Avoidance of unnecessary neurotoxic drugs and smoking or heavy alcohol exposure.

9. Good foot care, well-fitting shoes and regular checks for skin damage or pressure areas.

10. Support for mental health and stress management to reduce burnout in both patient and family.

When to see a doctor urgently

You should contact a doctor (or emergency services, depending on severity) if:

• there is sudden worsening of weakness, new trouble walking, or repeated falls;

• new seizures, episodes of loss of consciousness or abnormal movements appear;

• breathing becomes difficult, especially when lying flat, or there are frequent chest infections;

• swallowing becomes hard, with choking or frequent chest infections from aspiration;

• there is severe or new pain that does not settle with usual measures;

• the child stops using skills they had before (regression in speech, movement or learning);

• any medicine causes worrying side effects such as severe sleepiness, confusion, breathing problems, rash or behavioural change;

• mood becomes very low, there is strong anxiety, or talk of self-harm (in any age);

• there is sudden change in hearing, such as new deafness or distressing ringing sounds;

• you are unsure about any new symptom and feel things are “not right”.

Regular planned visits (for example every 6–12 months) with the specialist team are also essential even when things seem stable.

What to eat and what to avoid

What to eat more of (5 points)

1. Plenty of colourful fruits and vegetables every day to provide vitamins, minerals and antioxidants that support general health.

2. Adequate protein from fish, chicken, eggs, pulses, tofu and dairy (if tolerated) to maintain muscles and repair tissues.

3. Whole grains (brown rice, whole-wheat bread, oats) instead of refined grains to provide steady energy and fibre for bowel health.

4. Healthy fats from fish, nuts, seeds and plant oils to support cell membranes and hormone production.

5. Enough fluids (mainly water) throughout the day to prevent constipation and maintain circulation.

What to avoid or limit (5 points)

1. Sugary drinks and many sweets, which cause weight gain and do not provide useful nutrients.

2. Very salty processed foods (chips, instant noodles, processed meats), which can worsen blood pressure and fluid retention.

3. Heavy fried foods that add many calories and can lead to obesity and high cholesterol.

4. Excess caffeine (energy drinks) and any alcohol in older teens/adults, which may disturb sleep and can harm nerves and liver.

5. Extreme “fad diets” or very high-dose supplements taken without medical advice, which may lead to deficiencies or toxicity.

A dietitian who understands neurological conditions and local foods can make an individual meal plan.

Frequently asked questions

1. Is this disease curable?
   At present there is no cure that can correct the genetic problem or fully restore the missing large myelinated fibres. Treatment is supportive: it focuses on maximising abilities and preventing complications. Research into gene therapy and nerve repair is ongoing, but not yet ready for routine use.Orpha.net+1

2. Will my child’s condition always get worse?
   This syndrome is usually slowly progressive, but the speed of change varies between people. With good therapy, braces and environmental support, many children keep useful walking and hand function for a long time. Regular follow-up helps catch problems early so they can be managed.Kisho+1

3. How is this condition inherited?
   Reports suggest mainly autosomal recessive or X-linked inheritance in different families, meaning parents may be healthy carriers. A geneticist can explain the pattern in your family after reviewing tests and family history.NCBI+2MalaCards+2

4. Can another child in the family also have it?
   Yes, if both parents are carriers or if there is an X-linked pattern, there can be a significant recurrence risk. Genetic counselling and, where available, carrier or prenatal testing can clarify this risk.

5. What is the life expectancy?
   Because this disorder is very rare, long-term data are limited. Many children survive into adult life, especially with good respiratory care, fall prevention and early management of complications. Severe breathing or swallowing problems, if they occur, can affect prognosis, so these signs need quick attention.Orpha.net+1

6. Can my child go to regular school?
   Many children can attend mainstream school with support such as a classroom assistant, special seating, hearing support and extra time for tests. Some may need special education classes. The key is early communication between parents, doctors and school staff.

7. Is exercise safe, or will it damage the nerves?
   Gentle, regular exercise guided by physiotherapists is generally helpful. It keeps joints flexible and muscles stronger. Very intense exercise that causes strong pain or extreme fatigue should be avoided, but complete rest is harmful too.

8. Will hearing aids or cochlear implants restore normal hearing?
   These devices can greatly improve sound detection and understanding, especially when fitted early, but they usually do not create fully “normal” hearing. Speech therapy and quiet listening environments are still very important.

9. Can surgery cure the neuropathy?
   No. Surgery can correct deformities, improve posture or provide hearing through a cochlear implant, but it cannot repair the basic nerve damage. That is why rehabilitation must continue after surgery.

10. Are alternative therapies like acupuncture or herbal medicine helpful?
    Some people feel short-term relief from pain or stress with such therapies, but strong scientific evidence for this specific syndrome is lacking. Herbs can interact with medicines and be unsafe. Always discuss any alternative treatment with your doctor first.

11. Is it my fault that my child has this disease?
    No. Genetic conditions are not caused by anything parents did or did not do during pregnancy. Feeling guilty is common but not justified. What matters now is getting good information and support.

12. Can pregnancy be safe for someone with this condition?
    Many women with neuropathies can have safe pregnancies with high-risk obstetric and neurology care. Planning before pregnancy, adjusting medicines and monitoring breathing and mobility are important. A specialist should give individual advice.

13. What specialists should be in our care team?
    Ideally, a neurologist, geneticist, audiologist, physiotherapist, occupational therapist, speech therapist, psychologist, dietitian, orthopaedic surgeon and social worker. In many places, one or two specialists coordinate care and refer to others as needed.

14. How can we cope emotionally as a family?
    Ask for psychological support early, join support groups for rare diseases or neuropathies, and share tasks among family members. Keeping realistic goals, celebrating small gains and using respite services can reduce burnout.

15. What is the single most important thing we can do now?
    The most important step is to connect with an experienced neurologist or rare-disease centre, build a long-term care plan, and start early rehabilitation and hearing/education support. Information from the internet, including this answer, can guide questions but cannot replace personalised medical advice.
