Charcot-Marie-Tooth Disease Type 4 Caused by Mutation in GDAP1

Charcot-Marie-Tooth disease type 4 caused by mutation in GDAP1 (often called CMT4A) is a rare, inherited nerve disease. It mainly damages the peripheral nerves, which are the “wires” that carry signals from the brain and spinal cord to the muscles and from the skin back to the brain. In CMT4A, both motor nerves (movement) and sensory nerves (feeling) are affected, so it is called a sensorimotor neuropathy. The disease usually starts in infancy or early childhood and often progresses faster and is more severe than many other CMT types. GARD Information Center+1

Charcot-Marie-Tooth disease type 4A (CMT4A) is a severe inherited nerve disease that mainly affects the long nerves in the legs and arms. It is caused by harmful changes (mutations) in a gene called GDAP1, which helps keep nerve cells and their energy “power plants” (mitochondria) healthy. When GDAP1 does not work properly, the covering of the nerves (myelin) and the nerve fibers themselves slowly become damaged, so signals from the brain to the muscles travel more slowly or get lost.ScienceDirect+3PubMed+3MalaCards+3

CMT4A usually starts in childhood with weakness in the feet and legs, high-arched feet, foot drop, and problems with walking and balance. Later, weakness and numbness can also affect the hands and arms. The disease is progressive, which means symptoms slowly get worse over time, but the speed of worsening is different in each person, even in the same family.Wikipedia+3PMC+3ScienceDirect+3

CMT4A is usually a demyelinating neuropathy, which means it mainly attacks the myelin sheath, the fatty insulation that helps nerve signals travel quickly. However, in some people the pattern can be more axonal (direct damage to the nerve fiber core) or intermediate (mixed features). This damage makes nerve signals slow, weak, or blocked, which leads to muscle weakness, wasting, foot deformities, walking problems, and loss of sensation. GARD Information Center+1

This condition is inherited in an autosomal recessive way. That means a child has to receive one faulty copy of the GDAP1 gene from each parent to develop the disease. Parents who each carry one faulty copy usually do not have symptoms themselves. GARD Information Center+1

Other names

This disease is known by several other names in medical books and databases. These different names all describe the same or a very closely related condition:

• Charcot-Marie-Tooth disease type 4A (CMT4A)

• Charcot-Marie-Tooth disease type 4 caused by mutation in GDAP1

• Autosomal recessive demyelinating Charcot-Marie-Tooth disease type 4A

• GDAP1-related hereditary motor and sensory neuropathy (GDAP1-HMSN)

• Charcot-Marie-Tooth neuropathy type 4A

These names highlight that the disease is a type of CMT, is autosomal recessive, affects both motor and sensory nerves, and is caused by changes in the GDAP1 gene on chromosome 8q21. GARD Information Center+2MalaCards+2

Types

Researchers describe several patterns of disease linked to GDAP1 changes. All involve peripheral neuropathy, but the nerve damage can look slightly different in tests: PubMed+1

1. Classic CMT4A demyelinating type
   This is the main type the name refers to. Nerve conduction studies show very slow nerve conduction velocities, meaning the myelin is badly damaged. Symptoms start in infancy or early childhood, with early foot weakness, high-arched feet, and rapid progression.

2. Intermediate GDAP1 neuropathy
   In some people, nerve tests show conduction speeds that are not extremely slow but still below normal. This “intermediate” pattern has features of both demyelinating and axonal damage. Symptoms can still start early but may be slightly less severe.

3. Axonal GDAP1 neuropathy (CMT2K / related forms)
   Other GDAP1 mutations can cause a mainly axonal form of CMT (often called CMT2K), which may appear later and sometimes be milder. Even though the gene is the same, the exact mutation changes how the nerve is injured, so the pattern is different.

4. Early-onset severe vs later-onset milder forms
   Some GDAP1 mutations cause very early onset and severe disability, while others allow walking for many years and slower progression. GeneReviews and case reports show wide variation even within GDAP1-linked disease. PubMed+1

Causes and related factors

The main cause of this disease is mutation in the GDAP1 gene. Below are 20 related causes or contributing factors that explain how and why the disease appears and how it may vary between people.

1. Autosomal recessive inheritance of two faulty GDAP1 copies
   The core cause is inheriting two mutated GDAP1 genes, one from each parent. This leads to loss or major reduction of normal GDAP1 protein function in peripheral nerves, and that directly causes CMT4A. GARD Information Center+1

2. Missense mutations in GDAP1
   Some patients have missense mutations, where a single DNA “letter” change makes one wrong amino acid in the GDAP1 protein. This can alter the protein’s shape so it cannot do its normal job in nerve cells. Redalyc+1

3. Nonsense mutations in GDAP1
   Nonsense mutations create a premature stop signal in the gene, so the protein is cut short or not made at all. This usually causes a more severe loss of GDAP1 function and more severe neuropathy. Redalyc+1

4. Frameshift mutations
   Small insertions or deletions in the GDAP1 gene can shift the reading frame (“frameshift”), producing a completely abnormal protein. These often behave like nonsense mutations and cause severe disease starting in early childhood. Redalyc

5. Splice-site mutations
   Some changes occur at splice sites, the regions that tell the cell how to cut and join gene segments. Wrong splicing can remove or add parts of the protein, again leading to a non-working GDAP1 protein. Redalyc

6. Large deletions or duplications of GDAP1
   Rarely, a whole part of the GDAP1 gene is deleted or duplicated. These structural changes also disrupt protein production and can cause CMT4A. Genetic panels can detect these copy-number changes. mayocliniclabs.com+1

7. GDAP1 mutations mainly affecting Schwann cells and myelin
   Some variants mainly damage Schwann cells, the cells that make myelin. When these cells fail, the myelin sheath becomes thin or lost, leading to the demyelinating pattern typical of CMT4A. ScienceDirect+1

8. GDAP1 mutations mainly affecting axons
   Other variants may impair the axon itself, especially its energy supply and structure. This can create an axonal or intermediate pattern, which is still part of GDAP1-related neuropathy but may be labeled differently (e.g., CMT2K). ScienceDirect+1

9. Mitochondrial fission problems
   GDAP1 is involved in mitochondrial dynamics, especially fission (splitting) of mitochondria in neurons. Abnormal mitochondrial shape and movement can starve long nerves of energy and make them more likely to degenerate. ScienceDirect+1

10. Increased oxidative stress in nerve cells
    When GDAP1 does not work, mitochondria may produce more reactive oxygen species (oxidative stress). This damages cell components and can speed up nerve fiber loss. ScienceDirect+1

11. Impaired calcium signaling in neurons
    Mitochondria also help control calcium levels inside cells. Disturbed calcium handling due to faulty GDAP1 can make nerves more fragile and easier to damage under stress. ScienceDirect+1

12. Disrupted transport of mitochondria along axons
    Long peripheral nerves need mitochondria to be moved along the axon. If GDAP1-related changes disturb this transport, distant parts of the nerve may not get enough energy, leading to distal muscle weakness and wasting. ScienceDirect+1

13. Consanguinity (parents related by blood)
    In some populations, CMT4A is more common in families where the parents are related (for example, cousins). This increases the chance that both parents carry the same GDAP1 mutation and pass it to their child. Springer Link+1

14. Family history of GDAP1 CMT
    Having relatives with GDAP1-related CMT strongly increases risk. Even if the exact mutation is unknown, a strong family history suggests an inherited cause, not an acquired neuropathy. NCBI+1

15. Compound heterozygous GDAP1 variants
    Some patients inherit two different harmful GDAP1 variants (one from each parent). Together they still disrupt GDAP1 function strongly enough to cause disease and may explain differences in severity between siblings. Wiley Online Library+1

16. Other neuropathy gene variants acting as modifiers
    Studies suggest that changes in other CMT genes (like MFN2, PRX or PMP22) may modify how severe GDAP1 disease becomes, even though they are not the main cause. This could partly explain variation in symptoms. ScienceDirect+1

17. General metabolic stress (for example, poorly controlled diabetes) in a person with GDAP1 mutations
    Conditions like diabetes or severe vitamin deficiencies do not cause CMT4A, but they can worsen nerve damage in someone who already has GDAP1-related neuropathy. So they act as aggravating factors. NCBI+1

18. Physical nerve trauma or repeated pressure
    Repeated ankle injuries, tight footwear, or prolonged nerve compression can further weaken already fragile nerves and muscles in people with CMT4A, making disability worse earlier. NCBI

19. Delayed diagnosis and lack of early supportive care
    Again, this does not cause the genetic disease, but if diagnosis is delayed, children may not get early physiotherapy, orthotics, or support. This can allow more contractures and deformities to develop. NCBI+1

20. Rare de novo GDAP1 mutation
    In most cases, the mutation is inherited, but in rare situations a new (“de novo”) GDAP1 mutation can appear in the egg or sperm. The affected child then has CMT4A even if parents are not carriers. PubMed+1

Symptoms and signs

1. Early walking delay
   Many children with CMT4A sit, stand, or walk later than expected. Parents may notice that the child takes longer to pull to stand or seems clumsy when trying to walk. GARD Information Center+1

2. Frequent falls and tripping
   Because the muscles that lift the front of the foot are weak, children may drag their toes and trip on uneven ground, leading to frequent falls and scrapes. GARD Information Center+1

3. Foot drop and steppage gait
   Weakness of the muscles at the front of the lower leg leads to foot drop. To avoid dragging the toes, the person may lift the knee higher than normal when walking, called a steppage gait. Orpha.net+1

4. High-arched feet (pes cavus)
   Muscle imbalance in the feet pulls the arch up, creating high-arched feet. This is a very common sign in CMT, including CMT4A, and often appears early. GARD Information Center+2monarchinitiative.org+2

5. Hammer toes or claw toes
   The small muscles of the toes weaken and tighten in the wrong positions. This can create hammer toes or claw-like toes, which may cause pain and problems with shoes. Orpha.net+1

6. Wasting of lower leg muscles (“inverted champagne bottle” legs)
   Over time, the muscles below the knee shrink (atrophy). The lower legs may look thin, while the thighs stay more normal in size, giving a shape sometimes compared to an inverted champagne bottle. GARD Information Center+1

7. Weakness in the hands and forearms
   As the disease progresses, weakness spreads to the hands. Fine tasks like buttoning clothes, writing, or opening jars become hard. GARD Information Center+1

8. Loss of feeling in feet and hands
   Many people lose sensation for light touch, vibration, or pain in the feet, and later in the hands. They may not feel small cuts or blisters, which increases the risk of unnoticed injuries. GARD Information Center+2monarchinitiative.org+2

9. Abolished or reduced tendon reflexes
   Deep tendon reflexes (like the knee-jerk) are often weak or absent. This is because the reflex arc depends on healthy peripheral nerves, which are damaged in CMT4A. GARD Information Center+2MalaCards+2

10. Hoarse voice and vocal cord paresis
    Some teenagers or young adults with CMT4A develop a hoarse voice. This can be due to vocal cord paresis, where the nerves to the vocal cords are weakened and do not move normally. GARD Information Center+2MalaCards+2

11. Skeletal deformities (scoliosis, chest deformity)
    Long-standing muscle imbalance around the spine and chest can lead to scoliosis (curved spine) or chest wall deformities. These may cause posture problems and sometimes breathing difficulties in severe cases. GARD Information Center+1

12. Delayed motor milestones overall
    Not only walking, but many motor skills (running, jumping, climbing stairs) may be delayed or awkward. Children often struggle in sports or physical education compared with peers. GARD Information Center+1

13. Neuropathic pain or discomfort
    Some people report burning, tingling, or electric-shock-like pain in their feet or hands. Others may have aching from abnormal posture or joint strain. Pain level varies widely between patients. NCBI+1

14. Easy fatigue when walking or standing
    Because muscles and nerves are weak, even short walks can cause tiredness and leg heaviness. People may avoid long distances or need frequent rests. Orpha.net+1

15. Breathing or swallowing problems in very severe cases
    In rare and severe forms, nerves to the diaphragm or throat muscles can be affected, which may lead to breathing or swallowing difficulties. This is uncommon but important for doctors to monitor. NCBI+1

---

Diagnostic tests

Physical examination

1. Full neurological examination
   The doctor checks muscle strength, tone, sensation, reflexes, and coordination in all limbs. In CMT4A, they often find distal weakness, reduced reflexes, and loss of sensation in a “glove and stocking” pattern, which suggests a length-dependent neuropathy. NCBI+1

2. Gait (walking) assessment
   The doctor watches how the patient walks. A steppage gait, tripping, and poor heel or toe walking suggest foot drop and distal weakness typical of CMT. They also check whether walking worsens with fatigue. Orpha.net+1

3. Inspection of feet and legs
   The shape of the feet (high arches, hammer toes), muscle bulk, and any calluses or pressure sores are carefully examined. Typical CMT deformities like pes cavus and thin calves strongly support the diagnosis. GARD Information Center+2monarchinitiative.org+2

4. Reflex testing with a hammer
   The doctor taps the knees, ankles, and sometimes upper limb tendons with a reflex hammer. In CMT4A, the ankle reflexes are often absent early, and knee reflexes may disappear later, which is very typical for a chronic polyneuropathy. GARD Information Center+2MalaCards+2

5. Cranial nerve and voice examination
   The doctor listens for hoarseness and examines eye movements, facial strength, and swallowing. In CMT4A, a hoarse voice may point to vocal cord paresis, a known feature of GDAP1-related disease. GARD Information Center+1

---

Manual and bedside functional tests

6. Heel-walk and toe-walk tests
   The patient is asked to walk on heels only and then on toes only. Difficulty heel walking suggests weakness of the muscles that lift the foot (dorsiflexors), while toe walking problems reveal weakness of calf muscles. These patterns fit CMT4A. NCBI+1

7. Simple balance tests (including Romberg test)
   The patient stands with feet together, eyes open and then closed. Losing balance with eyes closed can show sensory loss in the feet (proprioceptive loss), as often seen in length-dependent neuropathies like CMT. NCBI+1

8. Manual muscle testing for hand strength
   The doctor asks the patient to grip their fingers or squeeze a device. Weak finger spread, pinch, and grip strength indicate distal hand muscle weakness, which is common in more advanced CMT4A. PubMed+1

---

Laboratory and pathological tests

9. Basic blood tests to rule out other causes of neuropathy
   Tests such as blood sugar, vitamin B12, thyroid function, kidney and liver tests, and sometimes autoimmune markers are done. In CMT4A, these are usually normal, which helps exclude acquired neuropathies and supports a genetic cause. NCBI+1

10. Genetic testing focused on GDAP1
    Once CMT is suspected, a DNA test can directly sequence the GDAP1 gene to look for mutations. Finding biallelic pathogenic GDAP1 variants confirms CMT4A. PubMed+2GARD Information Center+2

11. Next-generation sequencing CMT panel
    Many centers use a multi-gene panel that includes GDAP1 and many other CMT genes. This is useful when the exact subtype is unclear. The panel can detect single base changes and small deletions or duplications. mayocliniclabs.com+1

12. Sural nerve biopsy (rarely needed now)
    In some older cases or where genetic testing was not available, doctors performed a nerve biopsy of the sural nerve in the leg. In GDAP1 CMT4A, this can show severe loss of myelinated fibers and signs of axonal atrophy. Today, biopsy is less common because genetic tests are better and safer. PubMed+1

13. Pathology stains and electron microscopy on nerve tissue
    If a biopsy is done, special stains and electron microscopy show thin or absent myelin, regenerative clusters, and damaged axons. These findings confirm a severe chronic neuropathy and support the diagnosis, although they are not specific only to GDAP1. PubMed+1

---

Electrodiagnostic tests

14. Nerve conduction studies (NCS)
    Electrodes are placed on the skin to measure the speed and size of nerve signals. In CMT4A, nerve conduction velocity is often very slow, confirming a demyelinating neuropathy, although some patients show intermediate or near-normal speeds with reduced amplitudes. GARD Information Center+2PubMed+2

15. Electromyography (EMG)
    A thin needle records electrical activity inside muscles. EMG in CMT4A shows signs of chronic denervation and reinnervation, meaning motor units have been lost and surviving units have tried to take over. This supports a chronic neuropathy rather than a muscle disease. NCBI+1

16. Repetitive nerve stimulation (to exclude neuromuscular junction disease)
    This test stimulates a nerve repeatedly while recording muscle responses. In CMT, the pattern is usually stable, while in diseases of the neuromuscular junction (like myasthenia gravis) the response drops. This helps rule out other conditions that can also cause weakness and fatigue. NCBI+1

17. Somatosensory evoked potentials (less common)
    In some centers, doctors use somatosensory evoked potentials (SSEPs) to study how sensory signals travel to the brain. Delayed signals support a peripheral conduction problem, fitting with CMT4A, though this test is not always needed. NCBI+1

---

Imaging tests

18. Spine X-ray to look for scoliosis
    X-rays of the spine can show curvature (scoliosis) or other skeletal deformities in patients with long-standing muscle imbalance. Detecting scoliosis early helps plan physical therapy, braces, or other management. ResearchGate+1

19. Foot and ankle X-rays
    X-rays of the feet show the degree of pes cavus, hammer toes, and joint changes. This helps orthopedic surgeons and physiatrists plan braces, insoles, or surgery if needed to maintain walking and reduce pain. Orpha.net+1

20. Muscle MRI or ultrasound of legs
    Imaging of the muscles can show fatty replacement and atrophy in distal leg muscles, matching clinical weakness. MRI or ultrasound is sometimes used in research or complex cases to better understand which muscles are most affected. NCBI+1

Goals of treatment in CMT4A

The main treatment goals in Charcot-Marie-Tooth disease type 4 caused by GDAP1 mutation are: keep walking and hand function for as long as possible, prevent deformities and contractures, reduce nerve pain, protect the skin and joints, and support emotional and social well-being. Most helpful treatments are non-pharmacological (therapies, orthoses, exercise, education), plus symptom-based medications and sometimes surgery for foot deformity.Wikipedia+3PMC+3nhs.uk+3

Non-pharmacological treatments (therapies and others)

(To keep the article within your word limit, each item is written in short, very simple language, but still explains description, purpose, and basic mechanism.)

1. Individualized physical therapy
Physical therapy is a planned exercise and stretching program made for the person’s exact weakness and tightness pattern. The purpose is to keep muscles flexible, maintain strength, and slow joint stiffness. It works by using gentle movement, repeated practice, and safe strengthening to support the nerves and muscles that are still working.PMC+2nhs.uk+2

2. Occupational therapy for daily activities
Occupational therapists teach easier ways to dress, write, use a phone or computer, and do household tasks. The purpose is to protect independence and reduce fatigue. The mechanism is to adapt tools (built-up handles, splints) and teach energy-saving methods so weak hands and arms can work more effectively.PMC+2Muscular Dystrophy Association+2

3. Ankle-foot orthoses (AFOs)
AFOs are lightweight plastic or carbon braces worn in the shoes to hold the ankle and foot in a better position, especially for foot drop. Their purpose is to prevent tripping, improve walking, and reduce strain on weak muscles. They work by mechanically lifting the front of the foot and stabilizing the ankle with every step.Muscular Dystrophy Association+2Physiopedia+2

4. Custom shoes and insoles
Special footwear with extra depth, soft cushioning, and shaped insoles supports high arches, clawed toes, or other deformities. The purpose is to spread pressure evenly, reduce calluses and pain, and improve balance. The mechanism is simple: reshaping how the foot rests on the ground so forces are less harmful.nhs.uk+2Wikipedia+2

5. Daily stretching program
Gentle stretching of calves, hamstrings, hips, and hand muscles keeps joints from becoming stuck (contractures). The purpose is to keep full range of motion so walking and hand use stay easier. Stretching slowly lengthens tight muscles and tendons, which reduces stiffness and pain over time.nhs.uk+2Muscular Dystrophy Association+2

6. Progressive strength training
Low-resistance, high-repetition exercises can strengthen muscles that are not completely denervated. The purpose is to support posture, walking, and grip. The mechanism is muscle adaptation: repeated safe loading signals muscle fibers to become stronger, while the therapist avoids over-fatigue that could worsen weakness.PMC+2ScienceDirect+2

7. Balance and gait training
Therapists practice walking on different surfaces, turning, and climbing stairs, sometimes with parallel bars or harnesses. The aim is to reduce falls and build confidence. The mechanism is to retrain the brain and remaining sensory pathways to use visual cues and trunk muscles to replace lost ankle reactions.PMC+2Muscular Dystrophy Association+2

8. Aerobic (cardio) exercise
Low-impact activities like swimming, cycling, or walking in water help heart and lung health without overloading weak feet. The purpose is to improve endurance, mood, and overall energy. Aerobic exercise increases blood flow, supports mitochondrial function, and may improve fatigue in chronic nerve disease.PMC+2Physiopedia+2

9. Hand therapy and fine-motor training
Special exercises, putty, hand splints, and task practice help fingers stay flexible and coordinated. The purpose is to keep writing, buttoning, and phone use possible. The mechanism is repetitive movement that strengthens small muscles and helps the brain adapt to slower nerve signals.PMC+2Muscular Dystrophy Association+2

10. Respiratory physiotherapy (when needed)
In advanced or severe forms, weakness may affect breathing muscles. Breathing exercises, cough assist devices, and posture training can help. The purpose is to protect lung function and prevent infections. These methods work by improving chest expansion and helping clear mucus.PMC+2ScienceDirect+2

11. Orthotic support for hands and wrists
Soft or rigid splints can support weak wrists and fingers, especially for typing or lifting objects. The purpose is to reduce fatigue, pain, and joint deformity. The mechanism is external stabilization that lets tendons work in a better mechanical line, making movement easier.Muscular Dystrophy Association+2Physiopedia+2

12. Regular podiatry (foot-care) visits
A podiatrist cuts nails safely, removes calluses, checks for pressure spots, and advises on shoes. The purpose is to prevent wounds and ulcers in numb feet. The mechanism is early detection and removal of friction points before they break the skin.nhs.uk+2Muscular Dystrophy Association+2

13. Pain psychology and cognitive-behavioural therapy (CBT)
Nerve pain and disability can cause anxiety and low mood. CBT and similar therapies teach coping skills and pacing. The purpose is to reduce the suffering linked with pain and chronic illness. They work by changing thought patterns and behaviours that make pain feel worse.PMC+2ScienceDirect+2

14. Walking aids (cane, crutches, walker)
Canes or walkers can be used when balance is poor or fatigue is high. The purpose is to prevent falls and keep people mobile for longer distances. They work by providing extra points of support so body weight is shared between arms and legs.Muscular Dystrophy Association+2PubMed+2

15. Home and school safety adaptations
Handrails, non-slip mats, ramps, and better lighting reduce fall risk at home or school. The purpose is to match the environment to the person’s abilities. The mechanism is simple injury prevention: fewer hazards mean fewer accidents as balance and sensation worsen.Wikipedia+2Wikipedia+2

16. Vocational and educational rehabilitation
Teachers and employers can adjust tasks, schedules, and tools. The purpose is to keep study or work possible even with weakness. The mechanism is job redesign: choosing roles that use brain skills more than heavy physical strength and allowing rest breaks.PMC+2Muscular Dystrophy Association+2

17. Patient education and self-management training
Learning about CMT4A, foot care, pacing, and early warning signs makes the person an active partner in care. The purpose is empowerment and early problem detection. Education works by improving understanding so people seek help before damage becomes severe.Muscular Dystrophy Association+2Charcot-Marie-Tooth Association+2

18. Genetic counselling for family planning
Genetic counsellors explain inheritance of GDAP1 mutations, testing options, and recurrence risk in future children. The purpose is informed decisions for the person and family. It works by giving clear, science-based information about autosomal recessive or dominant patterns seen with GDAP1.PubMed+2MalaCards+2

19. Peer support groups and patient organizations
CMT organizations and online communities connect people with similar problems. The purpose is emotional support, sharing practical tips, and reducing isolation. Support works by normalizing feelings and giving realistic hope from people living with the same disease.Charcot-Marie-Tooth Association+2Charcot-Marie-Tooth Association+2

20. General nutrition and sleep hygiene
Healthy meals, adequate protein, and good sleep routines support overall strength and immune function. The purpose is to give the body the best base to handle chronic disease. The mechanism is indirect: good nutrition and rest support muscles, nerves, and mood, which affects how symptoms are felt.PMC+2Frontiers+2

Drug treatments (symptom-based, evidence-informed)

Important: none of these drugs cure GDAP1-related CMT4A. They are used off-label or by analogy to other neuropathies for pain, cramps, mood, or sleep. Doses below are typical adult ranges from FDA labels or reviews; exact doses must be set by a doctor for each person.

1. Gabapentin (Neurontin and other brands)
Gabapentin is an anti-seizure medicine widely used for nerve pain in conditions like post-herpetic neuralgia and diabetic neuropathy. Typical adult doses for neuropathic pain range from 900–3600 mg per day in divided doses, titrated slowly. It reduces abnormal pain signalling in the spinal cord by binding to calcium-channel subunits, and common side effects are sleepiness, dizziness, and swelling.PMC+4FDA Access Data+4FDA Access Data+4

2. Pregabalin (Lyrica / Lyrica CR)
Pregabalin is a related drug approved for several forms of neuropathic pain. Adult neuropathic pain doses are usually 150–600 mg per day, taken in 2–3 doses, adjusted for kidney function. It lowers the release of excitatory neurotransmitters in pain pathways, which can reduce burning or shooting pain; common side effects include dizziness, weight gain, and blurred vision.HPSJ/MVHP+5FDA Access Data+5FDA Access Data+5

3. Duloxetine (Cymbalta)
Duloxetine is a serotonin-noradrenaline re-uptake inhibitor (SNRI) approved for diabetic peripheral neuropathic pain and chronic musculoskeletal pain. A usual adult dose for neuropathic pain is 60 mg once daily. It boosts brain levels of serotonin and noradrenaline, which modulate pain signals and mood. Nausea, dry mouth, and sleep changes are common side effects.FDA Access Data+3FDA Access Data+3FDA Access Data+3

4. Amitriptyline
Amitriptyline is a tricyclic antidepressant used at low doses for chronic neuropathic pain and sleep problems. Doctors often start with 10–25 mg at night and increase slowly if needed. It blocks re-uptake of serotonin and noradrenaline and also affects pain pathways; side effects include dry mouth, constipation, weight gain, and drowsiness, so careful medical supervision is essential.FDA Access Data+2FDA Access Data+2

5. Nortriptyline
Nortriptyline is another tricyclic antidepressant sometimes preferred in older adults because it may cause slightly fewer side effects than amitriptyline. Typical pain doses are 10–75 mg once daily at night, adjusted slowly. It works by similar monoamine re-uptake inhibition and sodium-channel effects. Doctors must monitor heart rhythm and anticholinergic side effects.FDA Access Data+2FDA Access Data+2

6. Baclofen (oral formulations such as Ozobax, Lyvispah, others)
Baclofen is a muscle-relaxant that reduces spasticity and cramps by activating GABA-B receptors in the spinal cord. Oral adult doses are usually titrated from 5 mg three times daily up to around 80 mg per day in divided doses, depending on tolerance. It can reduce painful muscle tightness but may cause sleepiness, weakness, or dizziness.FDA Access Data+3FDA Access Data+3FDA Access Data+3

7. Intrathecal baclofen (Lioresal Intrathecal)
In very severe spasticity, baclofen can be delivered into the spinal fluid via an implanted pump. Doses are much smaller and are carefully adjusted by specialists. This method directly targets spinal circuits and can strongly reduce spasticity, but it carries risks such as pump failure, infection, or withdrawal if the drug is suddenly stopped.FDA Access Data+2FDA Access Data+2

8. Tizanidine (Zanaflex)
Tizanidine is a short-acting muscle relaxant that acts as an alpha-2 adrenergic agonist. It can be used for painful muscle spasms and stiffness. Adult doses are usually started at 2–4 mg up to three times a day and carefully increased. It reduces muscle tone by decreasing excitatory input to motor neurons; side effects include low blood pressure, dry mouth, and sleepiness.FDA Access Data+3FDA Access Data+3FDA Access Data+3

9. Simple analgesics (paracetamol / acetaminophen)
Acetaminophen is often used as a first step for mild musculoskeletal pain or headaches linked with abnormal posture. Typical adult dosing is up to 3–4 g per day in divided doses, but doctors must adjust for liver disease. It works mainly in the central nervous system to reduce pain and fever; overdose can cause serious liver injury.PMC+2ScienceDirect+2

10. Non-steroidal anti-inflammatory drugs (NSAIDs, e.g., ibuprofen, naproxen)
NSAIDs can help with joint and soft-tissue pain caused by abnormal walking or foot deformity, though they do not treat nerve damage. They work by blocking cyclo-oxygenase enzymes and reducing inflammatory prostaglandins. Doses and duration must be limited to reduce stomach, kidney, and heart risks, especially in long-term use.PMC+2Wikipedia+2

11. Tramadol (short-term, selected cases)
Tramadol is a weak opioid with additional serotonin and noradrenaline re-uptake effects. In some patients with severe neuropathic pain not controlled by other drugs, doctors may prescribe small doses for short periods. It changes pain perception in the brain, but carries risks of dependence, dizziness, and serotonin syndrome, so careful supervision is essential.PMC+2PMC+2

12. Topical lidocaine patches
Lidocaine 5% patches can be placed on painful skin areas (for example, localized burning pain). The medicine numbs superficial nerve endings and reduces abnormal firing. Patches are usually worn up to 12 hours per day on intact skin. Side effects are mostly local skin irritation, and systemic absorption is low when used correctly.PMC+2ScienceDirect+2

13. Capsaicin topical treatments
Capsaicin creams or high-dose patches can be used in some forms of localized neuropathic pain. Capsaicin over-stimulates pain-sensing fibers and then makes them less responsive for a time. The purpose is to reduce burning pain; however, it can cause strong local burning at first, so it must be used exactly as directed by a clinician.PMC+2PMC+2

14. Serotonin–noradrenaline re-uptake inhibitors other than duloxetine (e.g., venlafaxine, off-label)
Venlafaxine can sometimes help neuropathic pain and depression together. It increases serotonin and noradrenaline in brain synapses, which modulates pain pathways. Doses vary widely (often 75–225 mg/day in adults), and side effects may include increased blood pressure, nausea, and insomnia, so medical monitoring is important.PMC+2FDA Access Data+2

15. Selective serotonin re-uptake inhibitors (SSRIs, e.g., sertraline, citalopram)
SSRIs do not strongly treat neuropathic pain but are used to manage depression and anxiety in chronic CMT4A. They work by increasing serotonin levels in the brain. Better mood and sleep can indirectly improve pain coping and daily activity. Doses and side effects depend on the chosen drug and require medical guidance.PMC+2PMC+2

16. Short-term benzodiazepines for acute severe muscle spasms (e.g., diazepam)
In rare cases, diazepam may be prescribed short term for crisis muscle spasms. It potentiates GABA-A receptor activity and relaxes muscles. Because it can cause strong sedation, dependence, and falls, it is usually reserved for specific situations under close supervision, not as a routine long-term therapy.FDA Access Data+2FDA Access Data+2

17. Sleep aids (non-benzodiazepine hypnotics, carefully selected)
Severe pain or cramps can disturb sleep. Short-term use of specific sleep medicines may help while other treatments are adjusted. These drugs act on brain receptors that control sleep–wake cycles. Doctors weigh benefits against risks like daytime drowsiness, confusion, or dependence, especially in people with balance problems.PMC+2PMC+2

18. Antispasticity combinations (e.g., baclofen with tizanidine, under specialist care)
In some complex cases, specialists combine low doses of more than one antispastic drug to achieve better muscle control with fewer side effects. The purpose is to fine-tune tone without causing too much weakness. This requires expert monitoring of blood pressure, liver function, and mental alertness.FDA Access Data+3FDA Access Data+3FDA Access Data+3

19. Combination neuropathic pain regimens (for example, pregabalin plus alpha-lipoic acid in other neuropathies)
Research in diabetic neuropathy has tested combinations like pregabalin plus alpha-lipoic acid to improve pain control. Although not specific to CMT4A, doctors may use similar logic off-label when single drugs are not enough. The mechanism is targeting pain signalling and oxidative stress together. Evidence is still emerging and must be weighed carefully.Cureus+3NCBI+3MDPI+3

20. PXT3003 (baclofen–naltrexone–sorbitol combination, experimental)
PXT3003 is an oral combination being studied for CMT1A, not CMT4A, but it shows how future disease-modifying drugs might work. It aims to correct abnormal over-expression of PMP22 and improve myelin. For now, it remains investigational and is not part of standard treatment, but it represents a research direction for inherited neuropathies.PMC+2ScienceDirect+2

Dietary molecular supplements

These supplements are being studied mainly in other neuropathies (especially diabetic), not specifically in GDAP1-CMT4A. Any supplement plan must be checked with a doctor to avoid interactions or toxicity.

1. Alpha-lipoic acid (ALA)
Alpha-lipoic acid is an antioxidant that works in mitochondria and may reduce oxidative stress in nerves. Studies in diabetic neuropathy used oral doses around 600 mg/day and showed modest improvements in pain and nerve conduction. It may help by neutralizing free radicals and improving blood flow to nerves, but long-term safety and benefit in CMT4A are not yet proven.Cochrane Library+4MDPI+4PubMed+4

2. Coenzyme Q10 (CoQ10)
CoQ10 is a key mitochondrial molecule that helps make energy (ATP) and also acts as an antioxidant. Doses in mitochondrial disease studies often range from 100–300 mg/day or more, divided. It may support nerve cells by improving mitochondrial function and reducing oxidative damage, but evidence in inherited neuropathies like CMT4A is still limited and mostly experimental.SAGE Journals+3PubMed+3PNAS+3

3. Omega-3 fatty acids (fish-oil EPA/DHA)
Omega-3 fatty acids from fish oil have anti-inflammatory and nerve-protective actions. Clinical and animal data suggest they may help maintain nerve integrity and sometimes reduce neuropathic pain, though results are mixed. Typical supplement doses are often 1–3 g/day of combined EPA/DHA, adjusted by doctors. They work by changing cell-membrane lipids and lowering inflammatory cytokines.Omegor.com+4PMC+4Cochrane+4

4. Vitamin D3
Vitamin D deficiency is linked with higher rates of neuropathic pain and worse nerve function. Supplement doses depend strongly on blood levels but often range from 800–2000 IU/day in adults, with higher therapeutic courses under medical supervision. Vitamin D supports nerve health, bone strength, and immune balance; correcting deficiency may reduce pain in some neuropathies.ScienceDirect+3PMC+3Frontiers+3

5. B-complex vitamins (especially B1, B6, B12 in safe doses)
B-vitamins help nerves make energy and repair myelin. Controlled doses of thiamine (B1), pyridoxine (B6, not in high doses), and methylcobalamin (B12) are often used as supportive therapy in neuropathy. They act as co-factors in metabolic pathways, but mega-doses, especially of B6, can actually cause nerve damage, so medical advice is essential.Cochrane Library+3PubMed+3ClinicalTrials.gov+3

6. Acetyl-L-carnitine
Acetyl-L-carnitine helps transport fatty acids into mitochondria for energy production. Some studies in other neuropathies suggest it may support nerve regeneration and reduce pain. Typical study doses range from 500–1000 mg two or three times daily. It may improve mitochondrial efficiency and nerve fiber repair, but evidence in CMT4A is still weak.PubMed+2ScienceDirect+2

7. Curcumin (from turmeric)
Curcumin is an anti-inflammatory and antioxidant molecule found in turmeric. It may reduce neuro-inflammation and oxidative damage in experimental nerve injury models. Absorption is improved with formulations containing piperine or lipids. It can support general anti-inflammatory status but should be used carefully in people on blood thinners or with gallbladder disease.PMC+2Dove Medical Press+2

8. Resveratrol
Resveratrol is a polyphenol with antioxidant and mitochondrial-supporting effects in experimental models. It may activate pathways like SIRT1 and help protect nerves from metabolic stress. Doses in human studies vary widely; for CMT4A it would only be considered experimental supportive therapy, not a proven treatment.PubMed+2PNAS+2

9. Magnesium
Magnesium participates in nerve signalling and muscle relaxation. Correcting low magnesium levels may help cramps and muscle tightness in some people. Oral magnesium has to be dosed carefully (often 200–400 mg elemental magnesium per day) to avoid diarrhoea and in kidney disease. It works by stabilizing nerve membranes and controlling calcium entry into cells.PMC+2ScienceDirect+2

10. Antioxidant multinutrient formulas (combined vitamins, minerals, ALA, etc.)
Some clinicians use combined antioxidant formulas containing vitamins C and E, selenium, ALA, and other nutrients to reduce oxidative stress. The idea is that multiple antioxidants acting together may better protect nerve membranes and mitochondria. However, high-quality evidence is limited, and doses must be chosen to avoid excessive intake of fat-soluble vitamins.MDPI+2PubMed+2

Advanced and experimental therapies

At present, there are no approved regenerative or stem-cell drugs specifically for GDAP1-related CMT4A. The points below describe research directions only; they are not standard treatments and have no routine dosing.

1. Gene therapy targeting GDAP1
Researchers are exploring gene-replacement or gene-editing methods (such as viral vectors delivering a healthy GDAP1 copy) to correct the primary defect. The purpose is to restore normal protein in nerve cells and stop progression. This would work by enabling cells to produce functional GDAP1 and protect mitochondria and axons, but it is still experimental.PubMed+2ScienceDirect+2

2. Neurotrophic factor–based therapies
Neurotrophins (like NGF, BDNF, and others) support nerve growth and survival. Drug or biologic strategies to boost these factors or mimic their action are being studied in inherited neuropathies. The aim is to protect existing axons and encourage regrowth, but balancing effectiveness and side effects has been challenging in clinical trials.ScienceDirect+2Wikipedia+2

3. Small-molecule mitochondrial protectors
Because GDAP1 is linked with mitochondrial function, drugs that protect or stabilize mitochondria are of interest. Examples include CoQ10 precursors or agents that improve mitochondrial biogenesis. Studies in other mitochondrial diseases show improved neurological symptoms in some cases, but CMT4A-specific trials are lacking.SAGE Journals+3PubMed+3PNAS+3

4. Hematopoietic or mesenchymal stem-cell therapy (experimental)
Stem-cell infusions are being investigated in several neuro-degenerative diseases, aiming to release growth factors, modulate immunity, or replace damaged cells. For CMT, early experimental work is ongoing, but there is no proven protocol, standard dose, or long-term safety data. Most experts recommend using stem-cell therapy only in approved trials.ScienceDirect+2Wikipedia+2

5. Immunomodulatory therapies in overlap syndromes
If a person with CMT4A also has an autoimmune neuropathy or autoimmune disease, doctors may use drugs like corticosteroids, IVIG, or other immunosuppressants. The purpose is to control the immune component, not to treat the genetic CMT itself. These medicines change immune-cell activity and need close specialist control.PMC+2ScienceDirect+2

6. Combination disease-modifying strategies (future)
Future treatment may combine gene therapy, mitochondrial support, and physical rehabilitation. Animal studies and early human trials in other genetic neuropathies suggest that combining approaches can give better functional results than one method alone. For now, this remains a research vision rather than a real-world option.ScienceDirect+3ScienceDirect+3Charcot-Marie-Tooth Association+3

Surgical options

1. Soft-tissue releases (plantar fascia and tendon lengthening)
In feet with very high arches and tight soft tissues, surgeons may release or lengthen the plantar fascia and tight tendons. The goal is to allow the foot to sit flatter and reduce clawed toes. This works by removing tight structures that are pulling the foot into a deformed shape, improving comfort and shoe fit.Wikipedia+3PubMed+3jfootankle.com+3

2. Tendon transfer procedures
In tendon transfer surgery, strong working tendons are moved to help weak muscles, for example to lift the foot (dorsiflexion) or balance the ankle. The purpose is to correct foot drop and improve walking without always needing a brace. The transferred tendon gradually learns a new function and can rebalance muscle forces.ENMC+3PubMed+3www.elsevier.com+3

3. Osteotomy (bone-cutting to realign the foot)
Osteotomies reshape bones of the heel or mid-foot to correct cavovarus (high-arched, inward-tilted) deformity. They are done to improve weight distribution, reduce pain, and make walking safer. By cutting and repositioning bones, surgeons create a more stable, plantigrade foot that works better with or without braces.ScienceDirect+3PubMed+3www.elsevier.com+3

4. Toe correction surgery (claw toe and hammertoe repair)
Claw toes can cause painful pressure points and ulcers. Surgery can straighten the toes by releasing tight tendons, fusing small joints, or shortening bones. The purpose is to reduce pain, improve shoe comfort, and protect the skin. Correcting toes can also improve balance by giving a more stable forefoot.Wikipedia+3Charcot-Marie-Tooth Disease+3jfootankle.com+3

5. Joint fusion in severe, rigid deformities
If deformity is very stiff and painful, surgeons may fuse some joints in a better position (arthrodesis). The purpose is to create a solid, plantigrade foot that does not collapse or rub in abnormal areas. Fusion removes motion at the painful joint but can greatly improve stability and reduce chronic pain in selected patients.Ovid+3ENMC+3ResearchGate+3

Prevention and lifestyle strategies

1. Start therapy early – Begin physical and occupational therapy as soon as CMT4A is diagnosed to slow contractures and deformity.PMC+2Muscular Dystrophy Association+2

2. Use orthoses and shoes consistently – Wear prescribed braces and custom shoes every day to reduce falls and joint damage.nhs.uk+2Muscular Dystrophy Association+2

3. Protect the feet – Inspect feet daily for blisters or cuts, keep skin moisturized, and avoid walking barefoot to prevent ulcers.nhs.uk+2Wikipedia+2

4. Maintain healthy weight – Extra body weight stresses weak feet and joints; a balanced diet helps reduce strain and improves stamina.PMC+2Frontiers+2

5. Avoid nerve-toxic medications when possible – Some chemotherapy drugs and high-dose vitamin B6 can worsen neuropathy; doctors try to avoid them or monitor carefully.ScienceDirect+2Cochrane Library+2

6. Prevent falls at home and school – Remove loose rugs, add grab bars, and use handrails on stairs to reduce fracture risk.Wikipedia+2Wikipedia+2

7. Keep vaccinations up to date – Vaccines lower the risk of infections that can reduce mobility or cause hospitalization and deconditioning.PMC+2Frontiers+2

8. Manage mood and stress – Treating anxiety or depression with therapy and, if needed, medication can improve coping and participation in rehab.PMC+2PMC+2

9. Plan pregnancies with genetic counselling – Families can understand inheritance risk and consider options such as carrier testing or prenatal diagnosis.MalaCards+2SciELO Colombia+2

10. Join specialist CMT clinics or networks – Centres with CMT expertise can offer coordinated care, access to trials, and updated treatment advice.Charcot-Marie-Tooth Association+2Charcot-Marie-Tooth Association+2

Diet: what to eat and what to avoid

1. Eat balanced meals rich in vegetables and fruits
A colourful plate provides antioxidants and vitamins that support general nerve and muscle health and reduce oxidative stress.MDPI+2PMC+2

2. Include lean protein with each meal
Protein from fish, eggs, beans, and lean meat helps maintain muscle mass, which is important when nerves are weak.PMC+2Frontiers+2

3. Choose healthy fats (olive oil, nuts, seeds, fish)
These provide omega-3 and other helpful fats that support cell membranes and may reduce inflammation.PMC+2Dove Medical Press+2

4. Avoid frequent sugary drinks and sweets
High sugar intake increases the risk of diabetes, which can cause another layer of neuropathy and worsen symptoms.PMC+2Frontiers+2

5. Limit highly processed junk foods
Processed snacks often contain unhealthy fats, salt, and additives that do not nourish muscles or nerves and can promote weight gain.ScienceDirect+2The Times of India+2

6. Ensure enough vitamin D and calcium
Include dairy or fortified plant milks and safe sun exposure or supplements as advised to help bones stay strong when mobility is reduced.The Times of India+3PMC+3Frontiers+3

7. Avoid excessive alcohol
Alcohol can directly damage peripheral nerves and worsen balance. Limiting or avoiding alcohol protects nerve function.ScienceDirect+2ScienceDirect+2

8. Stay well hydrated with water
Dehydration can worsen fatigue and cramps. Regular water intake supports circulation and muscle function.PMC+2ScienceDirect+2

9. Be careful with high-dose supplements on your own
Mega-doses of certain vitamins or herbal products can harm nerves, liver, or kidneys. Always discuss with your doctor before starting new supplements.PubMed+2Cochrane Library+2

10. Adapt diet for other conditions (e.g., diabetes, kidney disease)
If the person also has diabetes or kidney problems, a specialist diet plan is vital to protect nerves and organs at the same time.ScienceDirect+2PMC+2

When to see a doctor

You should see a doctor (ideally a neurologist who knows about CMT) or seek urgent medical help if you notice any of the following:

• New or rapidly worsening weakness, especially sudden loss of ability to walk or stand.

• Sudden change in hand function, such as dropping objects constantly or not being able to hold a pen.

• Severe new pain, burning, or electric-shock sensations that do not improve with usual medicines.

• New breathing problems, shortness of breath at rest, or waking at night gasping for air.

• Frequent falls, fractures, or ankle sprains despite using braces or aids.

• Open sores, ulcers, or infections on the feet that do not heal quickly.

• Very low mood, thoughts of hopelessness, or trouble coping with daily life.

Regular follow-up (often once or twice a year, or more often if symptoms change) with the care team allows early adjustment of braces, therapy, and medications and early referral to surgery if deformities begin to fix in a bad position.Wikipedia+3PMC+3ScienceDirect+3

Frequently asked questions (FAQs)

1. Is there a cure for GDAP1-related CMT4A?
No, there is no cure at present. Treatment focuses on therapy, bracing, symptom control, and surgery when needed. Research in gene therapy and mitochondrial protection is ongoing but still experimental.ScienceDirect+3PMC+3ScienceDirect+3

2. Can exercise make CMT4A worse?
Gentle, planned exercise usually helps rather than harms. Over-strenuous workouts that cause deep, long-lasting fatigue or strong pain can be harmful. Working with a therapist ensures exercises stay in a safe zone.PMC+2Physiopedia+2

3. Why are braces so important in this disease?
Braces keep the foot and ankle in safer positions, reduce tripping, slow joint deformity, and save energy. They act like extra “external muscles” that support weak internal muscles while you walk.Muscular Dystrophy Association+2www.slideshare.net+2

4. Do pain medicines stop the disease from progressing?
No. Pain medicines change how pain is felt but do not change the underlying nerve damage. They are still important because controlling pain allows better sleep, mood, and participation in therapy.NCBI+3PMC+3ScienceDirect+3

5. Are gabapentin and pregabalin safe for long-term use?
They are commonly used long term for neuropathic pain, but they can cause side effects like dizziness, weight gain, and drowsiness. Doctors regularly review the dose, kidney function, and overall benefit–risk balance. Never stop them suddenly without medical guidance.PMC+5FDA Access Data+5FDA Access Data+5

6. Can surgery fix CMT4A completely?
Surgery can correct deformities and improve walking and comfort, but it does not repair the genetic nerve damage. The disease can still slowly progress, so surgery is usually combined with ongoing therapy and bracing.Ovid+3PubMed+3ScienceDirect+3

7. Should every person with CMT4A have surgery?
No. Surgery is considered when deformities are painful, rigid, or cause repeated falls despite good bracing and therapy. A CMT-experienced orthopedic surgeon will weigh benefits and risks for each person.Wikipedia+3Charcot-Marie-Tooth Association+3ENMC+3

8. Will supplements like alpha-lipoic acid or CoQ10 cure my neuropathy?
Current evidence suggests these supplements may modestly help pain or nerve function in some other neuropathies, but they do not cure CMT4A. They should be used, if at all, only as add-ons under medical supervision.ScienceDirect+3MDPI+3PubMed+3

9. Is it safe to take many supplements together?
Taking several products together can increase the risk of side effects or interactions with medicines. Some vitamins are harmful in very high doses. It is best to share a full list of supplements with your doctor or pharmacist.OmegaQuant+2PMC+2

10. How important is weight control in CMT4A?
Keeping a healthy weight reduces stress on weak feet, ankles, and knees and makes braces and walking aids more effective. It also lowers the risk of diabetes, which can cause additional nerve damage.PMC+2Frontiers+2

11. Can children with CMT4A play sports?
Many children can take part in low-impact sports such as swimming, cycling, or adapted games. The key is safety, good shoes or braces, and avoiding activities that cause repeated sprains or major fatigue. Decisions should be made with the care team and family.Physiopedia+2Muscular Dystrophy Association+2

12. Is pregnancy safe for someone with CMT4A?
Many people with CMT have successful pregnancies, but extra planning is needed. A neurologist, obstetrician, and anesthesiologist should review mobility, breathing, and family-planning questions, including genetic risks for the baby.MalaCards+2SciELO Colombia+2

13. Will CMT4A shorten life expectancy?
Most people with CMT, including CMT4A, have a normal life span, though severe forms can cause significant disability. Quality of life depends heavily on access to supportive care, therapy, and good management of complications.PMC+2ScienceDirect+2

14. How can families support someone with CMT4A?
Families can help by encouraging therapy attendance, checking for foot problems, supporting safe home changes, listening to emotional concerns, and joining education sessions together. Understanding the disease often reduces fear and misunderstanding.Muscular Dystrophy Association+2Charcot-Marie-Tooth Association+2

15. Where can I find trustworthy information and trial opportunities?
National CMT organizations, neuromuscular clinics, and clinical-trial registries are good sources. They provide evidence-based guides for therapy, surgery, and everyday living and may list research studies for inherited neuropathies.ScienceDirect+3Charcot-Marie-Tooth Association+3Charcot-Marie-Tooth Association+3
