Maroteaux–Malamut Syndrome

Maroteaux-Lamy syndrome is a rare, inherited condition. The body is missing, or has very low, activity of a lysosomal enzyme called arylsulfatase B (also called N-acetylgalactosamine-4-sulfatase). Because this enzyme is weak, certain natural sugars called glycosaminoglycans (GAGs) — mainly dermatan sulfate (and partly chondroitin sulfate) — are not broken down well. These GAGs build up inside cells and tissues over time. The buildup slowly harms many organs, especially bones and joints, eyes, heart valves, airways, and the liver and spleen. National Organization for Rare DisordersPMCWikipedia

Maroteaux–Malamut syndrome (acrodysostosis) is a rare condition present from birth that mainly affects the bones of the hands, feet, face, and sometimes hormone signaling. Children usually have short, broad fingers and toes (severe brachydactyly), small or under-developed facial bones—especially a small, up-turned nose (nasal hypoplasia)—and often short height. Some children have learning or developmental delays. In a portion of patients, the body does not respond normally to certain hormones (for example, thyroid-stimulating hormone or parathyroid hormone), a problem called hormone resistance. The disorder is usually caused by changes (variants) in one of two genes—PRKAR1A or PDE4D—which alter how cells handle a messenger called cAMP that carries signals from many hormones. There is no single curative medicine; care focuses on monitoring, supportive therapies, and treating specific problems early with a coordinated team. OrphaOxford AcademicPubMedNational Organization for Rare Disorders

The problem is due to harmful changes (pathogenic variants) in the ARSB gene. This gene gives the instruction to make arylsulfatase B. When ARSB does not work, GAGs accumulate. The disease is autosomal recessive. A child is affected when they inherit one non-working ARSB gene from each parent. PMCNational MPS Society MPS VI is very rare. Estimates vary by country, but it may affect about 1 in 250,000–600,000 births. National MPS Society Symptoms usually appear in childhood and slowly get worse with age. Intelligence is usually normal in MPS VI (unlike some other MPS types). MedlinePlus

Other Names

• Maroteaux-Lamy syndrome

• MPS VI or mucopolysaccharidosis type VI

• Arylsulfatase B (ARSB) deficiency

• N-acetylgalactosamine-4-sulfatase deficiency
  All these names refer to the same condition. National Organization for Rare DisordersPMC

Types

Doctors often group MPS VI by how fast it progresses and how severe the features are. These are not strict boxes, but they help plan care.

1. Severe / rapidly progressive form.
   Symptoms appear early (often in the first few years). Bone and joint problems move quickly. Heart valve disease and airway problems are more intense. Children are shorter, and spine and joint stiffness progress faster. PMC

2. Attenuated / slowly progressive form.
   Symptoms start later and move more slowly. People may grow a bit taller than those with severe disease and may keep better mobility for longer. Heart and airway issues can still happen and need regular checks. PMC

3. By organ focus (practical view).
   Some patients mainly have skeletal and joint issues; others show prominent eye (corneal) clouding; others have more cardiac valve or airway involvement. Most people have several systems involved to different degrees. EyeWiki

4. By enzyme “residual activity.”
   A tiny amount of remaining ARSB activity can soften the pace of disease. But the same enzyme level can look different in different people, so enzyme number alone does not perfectly predict severity. PMC

Causes

Important note: MPS VI has one primary cause: harmful variants in the ARSB gene leading to low or absent arylsulfatase B activity. Below are 20 clear ways or contexts this single cause appears in real life. Think of them as mechanisms, variant types, or factors that create or shape ARSB deficiency and its effects.

1. Biallelic ARSB variants (autosomal recessive).
   A person inherits two non-working ARSB copies (one from each parent). This is the core cause of MPS VI. PMCNational MPS Society

2. Missense variants.
   A single “letter” change alters one amino acid in the enzyme, often making the enzyme fold poorly or work less. Severity varies. PMC

3. Nonsense variants.
   A premature stop signal cuts the enzyme short, usually causing no functional enzyme. This often leads to severe disease. PMC

4. Frameshift variants.
   Small insertions or deletions shift the reading frame, producing a faulty enzyme. Usually severe. PMC

5. Splice-site variants.
   Changes near exon–intron borders disrupt normal splicing, creating abnormal enzyme protein. Severity can vary. PMC

6. Large deletions or duplications in ARSB.
   Bigger structural changes can remove parts of the gene or make it unreadable. PMC

7. Compound heterozygosity.
   Two different ARSB variants (one from each parent) combine in the same person, still causing deficiency. The mix can shape how fast disease moves. PMC

8. Very low residual enzyme activity.
   When ARSB activity is near zero, GAG buildup is faster, and symptoms progress more quickly. PMC

9. Protein misfolding with ER retention.
   Some variants create an enzyme that misfolds and gets trapped inside the cell’s quality-control system, never reaching the lysosome. PMC

10. Defective lysosomal targeting/trafficking.
    Even if the enzyme is made, it may fail to reach lysosomes where GAG breakdown happens. The effect looks like enzyme loss. PMC

11. Unstable enzyme at body temperature.
    Some altered enzymes break down quickly, so activity is too low inside cells. PMC

12. Founder variants in certain communities.
    A specific ARSB variant may be more common in a small population due to shared ancestry. This raises local risk. PMC

13. Consanguinity (parents related by blood).
    Increases the chance both parents carry the same rare ARSB variant, raising the chance of an affected child. National MPS Society

14. Allelic heterogeneity (many different ARSB variants exist).
    More than 150 ARSB mutations are reported. Different variants can cause different speeds of disease. PMC

15. Modifier genes (biologic background).
    Other genes that affect lysosomes, GAG production, or sulfation may slightly change how severe symptoms look, even with the same ARSB variant. (This is an inference supported by variability noted across patients.) PMC+1

16. GAG production rate (tissue workload).
    Tissues that naturally make more dermatan sulfate (e.g., connective tissues, heart valves, cornea) are hit harder because more substrate piles up. PMC

17. Delayed diagnosis.
    The longer GAGs accumulate without treatment, the more damage builds up. Early recognition helps care planning. PMC

18. Inflammation from stored GAGs.
    GAG storage can trigger low-grade inflammation and tissue remodeling, which worsens stiffness and organ changes over time. PMC

19. Mechanical stress on joints and spine.
    Stiff tissues with GAG buildup suffer under daily load, adding pain and contractures. PMC

20. Airway and cardiac valve vulnerability.
    Valves and airway walls contain connective tissue rich in dermatan sulfate, so storage strongly affects breathing and heart function. PMC

Symptoms

1. Coarse facial features.
   The face may look heavier over time. The nose bridge may be low. Lips can be thicker. This reflects GAG storage in facial tissues. National Organization for Rare Disorders

2. Short stature.
   Children often grow slowly. Adult height is usually lower than average because bones are affected. PMC

3. Skeletal changes (dysostosis multiplex).
   X-rays show typical bone signs: thickened bones, spine shape changes, and abnormal rib and pelvis shapes. These changes drive stiffness and pain. PMC

4. Joint stiffness and contractures.
   The range of motion shrinks. Hands may not fully open. Knees and hips feel tight. Stiffness worsens with age. PMC

5. Spine problems (kyphosis/scoliosis) and neck issues.
   The spine can curve. The neck may be short and stiff. In some, the spinal canal narrows and presses the spinal cord. This needs careful monitoring. PMC

6. Enlarged liver and spleen (hepatosplenomegaly).
   These organs store GAGs and get bigger. The belly can look full. MedlinePlus

7. Hernias (umbilical or inguinal).
   A bulge at the belly-button or groin is common and may need repair. MedlinePlus

8. Eye problems (corneal clouding).
   The clear front window of the eye gets cloudy. Vision becomes blurry and glare sensitivity increases. MedlinePlus

9. Hearing loss and ear infections.
   Fluid in the middle ear and structural changes can reduce hearing. Repeated ear infections are common. MedlinePlus

10. Heart valve disease.
    GAGs stiffen and thicken heart valves, leading to leaks or narrowing. Doctors often hear a murmur. PMC

11. Breathing and airway problems.
    Narrow airways and stiff chest wall cause snoring, sleep apnea, and shortness of breath. Chest infections may occur more often. PMC

12. Carpal tunnel syndrome.
    Nerve compression at the wrist causes hand numbness or pain. This can happen even in children with MPS VI. PMC

13. Dental and jaw issues.
    Teeth may be crowded. The jaw and facial bones develop differently, affecting bite and speech clarity. PMC

14. Fatigue and limited endurance.
    Walking distance is shorter. Climbing stairs is hard because of joint stiffness, spine issues, and heart–lung load. PMC

15. Usually normal intelligence.
    Unlike some other MPS disorders, thinking and learning are usually normal in MPS VI. Support for schooling may still be helpful due to physical challenges. MedlinePlus

 Diagnostic Tests

A) Physical Examination (at the bedside)

1. Overall growth and body build check.
   The doctor measures height, weight, head size, and body proportions to look for short stature and typical build.

2. Face and mouth exam.
   Coarsening of facial features and dental crowding can be seen on simple inspection.

3. Joint range of motion exam.
   The clinician gently moves each joint to see stiffness and contractures, especially hands, elbows, shoulders, hips, and knees.

4. Spine and posture exam.
   Observation and palpation check for kyphosis or scoliosis and for neck stiffness.

5. Abdominal palpation.
   The doctor feels for an enlarged liver and spleen and checks for hernias.

6. Heart and lung exam.
   Listening with a stethoscope (auscultation) may detect heart murmurs and reduced breath sounds related to airway or chest wall issues.

7. Eye exam with light.
   A simple penlight or slit-lamp by an eye doctor can show corneal clouding and help track changes. MedlinePlus

B) Manual / Functional Tests (simple, clinic-based performance measures)

8. Six-minute walk test (6MWT).
   Measures how far a person can walk in six minutes. It reflects endurance, joint function, and cardiorespiratory status. Often used to track change over time in MPS conditions. PMC

9. Hand function and grip assessment.
   Simple grip dynamometry and timed hand tasks show the impact of stiffness and carpal tunnel on daily activities.

10. Goniometry for range of motion.
    Using a small protractor device to measure joint angles helps quantify stiffness and contractures.

11. Respiratory function tests (spirometry).
    Blowing into a device shows how well the lungs and chest wall work. Restriction suggests chest stiffness or airway issues. PMC

12. Sleep screening questionnaires and oximetry.
    Simple tools can screen for snoring and nighttime low oxygen, helping decide if a formal sleep study is needed. PMC

C) Laboratory and Pathological Tests

13. Urinary GAGs analysis (quantitative).
    A lab measures total GAGs in urine (e.g., by DMB dye test). In MPS VI, levels are high. This is a key screening test. PMC

14. Urine GAGs pattern (qualitative by electrophoresis or LC–MS/MS).
    Shows the dermatan sulfate predominance typical of MPS VI, which helps distinguish it from other MPS types. PMC

15. Enzyme assay for ARSB activity (leukocytes or fibroblasts).
    Directly measures arylsulfatase B activity. Low activity confirms the biochemical diagnosis. This is a gold-standard test. PMC

16. Molecular genetic testing (ARSB sequencing).
    Identifies the exact ARSB variants. This confirms diagnosis, helps with genetic counseling, and allows family testing. PMC

17. Newborn screening (where available).
    Some regions test dried blood spots for lysosomal enzymes. Positive screens need confirmatory enzyme and genetic tests. Early detection helps care. PMC

18. Baseline blood tests for organ support.
    General labs (CBC, liver enzymes, inflammatory markers) help plan comprehensive care and monitor overall health during treatment. (Supportive practice in MPS care.) PMC

D) Electrodiagnostic Tests

19. Nerve conduction studies (NCS) with/without EMG.
    Checks for carpal tunnel syndrome or other nerve compressions common in MPS VI. Useful when hand numbness or pain appears. PMC

20. Polysomnography (overnight sleep study).
    Monitors breathing, oxygen, airflow, and brain/heart activity during sleep to detect obstructive sleep apnea, which is frequent in MPS VI. PMC

21. Electrocardiogram (ECG) ± Holter.
    Looks for heart rhythm changes related to valve disease and cardiac strain; helps guide cardiology care in conjunction with imaging. PMC

(I’ve listed three electrodiagnostic examples to give a realistic picture; clinics choose based on symptoms.)

E) Imaging Tests

22. Skeletal X-rays (full “bone survey”).
    Shows the classic dysostosis multiplex pattern in skull, spine, chest, pelvis, and limbs. This supports the diagnosis and tracks progression. PMC

23. Spine MRI (and sometimes CT).
    Evaluates the spinal cord, canal, and discs for narrowing or compression that might need surgery or bracing. PMC

24. Echocardiogram (heart ultrasound).
    Assesses valve thickening and leaks (regurgitation), chamber sizes, and pumping function. Repeated regularly to protect heart health. PMC

25. Abdominal ultrasound.
    Measures the size of the liver and spleen and checks for other abdominal issues without radiation.

26. Airway and chest imaging (X-ray or CT when needed).
    Looks at airway size, chest wall shape, and lungs if breathing symptoms are significant. PMC

27. Ophthalmic imaging (slit-lamp exam; corneal OCT if available).
    Documents corneal clouding and helps plan vision care; corneal thickness and clarity can be measured over time. MedlinePlus

28. Hearing assessment (audiology; may include ABR).
    Formal hearing tests, and in some cases auditory brainstem response (ABR), quantify hearing loss and guide use of tubes or hearing devices. MedlinePlus

Non-pharmacological treatments

Physiotherapy / rehabilitation approaches

1. Range-of-motion therapy: Gentle daily stretching to keep joints mobile and reduce stiffness; prevents contractures.

2. Strength training (low load, high reps): Builds endurance in forearms/hands and core muscles to support posture and fine-motor use.

3. Task-specific hand therapy: Repetitive practice (buttoning, zippers, writing) to improve dexterity and independence.

4. Splinting/orthoses: Custom wrist or thumb splints to stabilize joints and ease pain during tasks; night splints for carpal tunnel symptoms.

5. Posture and spinal stabilization: Core exercises and postural cues to reduce back pain and limit curvature progression.

6. Gait and balance training: Step drills and balance work to improve walking efficiency and reduce falls.

7. Hydrotherapy (aquatic PT): Warm-water sessions lower joint load and encourage full-range movement.

8. Pain-modulating modalities: Heat before exercise and ice after; therapist-guided TENS if appropriate.

9. Breathing and airway support exercises: Nasal breathing practice, positional training if sleep-disordered breathing is present (adjunct to ENT care).

10. Energy-conservation coaching: Pacing and rest-break planning for school/work days to avoid fatigue.

11. Manual therapy (soft-tissue work): Reduces muscle guarding around stiff joints; always gentle and within tolerance.

12. Ergonomic adaptations: Pencil grips, larger-handle utensils, keyboard alternatives to cut strain and increase speed.

13. Home exercise program (HEP): Short, daily routines the family can do safely at home; consistency beats intensity.

14. Fall-prevention training: Home safety walk-through, footwear advice, and obstacle-course practice to improve reactions.

15. Pre-/post-surgical rehab planning: If surgery is planned, prehab builds strength; post-op therapy restores motion and function.

Mind-body therapies

16. Cognitive-behavioral pain skills: Simple breathing, pacing, and reframing to reduce pain-related distress and improve participation.

17. Mindfulness for anxiety and focus: 5–10 minute daily practices can help attention and coping during therapies and school.

18. Sleep hygiene program: Regular bedtime, screen curfew, and quiet routines to improve energy, concentration, and pain thresholds.

Educational therapies

19. Individualized Education Plan (IEP): Tailor supports for fine-motor, writing, and any learning challenges; includes extra time, assistive tech.

20. Occupational therapy at school: Handwriting alternatives (speech-to-text), keyboarding, and adaptive classroom tools.

21. Speech-language therapy (if needed): For articulation or resonance issues linked to facial structure.

22. Transition/vocational planning: Early preparation for adult independence, including job skills that fit strengths.

Other supports

23. Nutritional counseling: Balanced calories to prevent excessive weight gain (helps joints); adequate calcium and vitamin D intake.

24. Dental/orthodontic care: Early referral for crowding or bite problems due to midface structure.

25. Genetic counseling: Explains inheritance, recurrence risks, and testing options for family planning. PMC

Drug treatments

Doses are typical starting ranges for education; exact prescriptions must be individualized by the child’s clinicians.

1. Levothyroxine (thyroid hormone replacement) — Class: thyroid hormone. Dose/time: ~1.6 mcg/kg/day in older children; infants need more per kg; taken once daily on empty stomach. Purpose: treat TSH resistance-related hypothyroidism. Mechanism: replaces T4. Side effects: over-dose causes palpitations, irritability. NCBI

2. Calcitriol — Class: active vitamin D. Dose: 0.25–1 mcg/day in divided doses. Purpose: manage PTH resistance by improving calcium absorption. Mechanism: bypasses impaired PTH signaling. Side effects: hypercalcemia if excessive. PMC

3. Calcium carbonate (elemental calcium) — Class: mineral supplement. Dose: often 500–1500 mg elemental Ca/day in divided doses as directed. Purpose: support calcium levels in PTH resistance. Mechanism: provides substrate for absorption. Side effects: constipation. PMC

4. Sevelamer (or other phosphate binder) — Class: non-calcium phosphate binder. Dose: individualized. Purpose: control high phosphate if present in PTH resistance. Mechanism: binds dietary phosphate in gut. Side effects: GI upset. PMC

5. Cholecalciferol (vitamin D3) — Class: vitamin. Dose: common maintenance 600–1000 IU/day (per labs/guidelines). Purpose: correct deficiency that worsens bone health. Mechanism: replenishes stores. Side effects: rare at physiologic doses.

6. Acetaminophen (paracetamol) — Class: analgesic. Dose: 10–15 mg/kg every 4–6 h PRN. Purpose: musculoskeletal pain. Mechanism: central COX modulation. Side effects: liver risk if overdosed.

7. Ibuprofen — Class: NSAID. Dose: 5–10 mg/kg every 6–8 h with food. Purpose: joint pain/inflammation flares. Mechanism: COX inhibition. Side effects: stomach upset.

8. Naproxen — Class: NSAID. Dose: pediatric dosing per weight, often twice daily. Purpose: longer-acting pain control. Side effects: GI irritation.

9. Topical NSAIDs (e.g., diclofenac gel) — Class: topical analgesic. Use: local pain in small joints. Benefit: fewer systemic effects.

10. Gabapentin — Class: neuropathic pain modulator. Dose: titrated low to effect. Purpose: nerve pain from entrapment (e.g., carpal tunnel). Side effects: sleepiness, dizziness.

11. Amitriptyline (low dose at night) — Class: tricyclic. Purpose: chronic pain, sleep. Mechanism: central pain modulation. Side effects: dry mouth, sedation.

12. Intranasal corticosteroid (e.g., fluticasone) — Use: nasal obstruction/allergic inflammation that worsens breathing or sleep quality.

13. Melatonin — Use: sleep-onset issues; start with very low dose at night.

14. Antibiotics (short courses as needed) — Use: ENT/dental infections promptly, given anatomic crowding risk.

15. Growth hormone (specialist-decided only) — Some sources note it may be considered in selected situations, but benefit in acrodysostosis is uncertain and may be limited by signaling issues; this requires careful endocrine evaluation and monitoring. MedlinePlus

Important reality check: There are no standardized drug protocols specific to acrodysostosis; treatment is tailored to the person’s symptoms, especially endocrine findings, with a multidisciplinary team. National Organization for Rare DisordersRare Awareness Rare Education Portal

Dietary molecular supplements

(Use only with clinician approval and lab monitoring, especially if you have hormone resistance.)

1. Vitamin D3 — typical maintenance 600–1000 IU/day; supports bone mineralization.

2. Calcium — see above; combines with calcitriol when indicated.

3. Magnesium — helps PTH secretion/action; use if deficient.

4. Omega-3 fatty acids — general anti-inflammatory support; may ease joint discomfort.

5. Protein (adequate dietary intake) — supports muscle strengthening and rehab gains.

6. Collagen peptides — may support joint comfort; adjunct only.

7. B-complex — supports energy metabolism and nerve health; corrects dietary gaps.

8. Iron — only if anemic; improves stamina and sleep quality.

9. Probiotics — may improve GI tolerance when using calcium or binders.

10. Multinutrient for teens — fills micronutrient gaps in picky eaters; avoid mega-doses.

---

Regenerative / stem-cell” drugs:

For acrodysostosis, there are no approved immune-booster medicines, “regenerative drugs,” or stem-cell therapies that correct the bone pattern or hormone signaling. Stem-cell or gene-editing ideas (e.g., targeting cAMP-pathway genes) remain research-only and are not recommended outside ethics-approved trials. If you encounter offers for “stem-cell cures,” treat them as unsafe and unproven. Safer, effective “regeneration” in practice is the body’s own adaptation supported by physiotherapy, nutrition, surgical correction when needed, and timely endocrine care. (Authoritative reviews emphasize symptomatic, team-based management rather than curative drugs.) Rare Awareness Rare Education PortalOrpha

---

Surgeries

1. Carpal tunnel release — if nerve-conduction tests confirm median-nerve compression causing pain/numbness; relieves pressure and improves hand function.

2. Corrective osteotomy / digit procedures — selected cases to improve alignment or function of very short/stiff digits; goal is better grip and daily use.

3. Spinal surgery — for severe scoliosis/stenosis not controlled conservatively; aims to protect the spinal cord and reduce pain.

4. Orthognathic/craniofacial procedures — to address bite problems, airway crowding, or significant facial imbalance; can improve chewing, speech, and breathing.

5. Adenotonsillectomy / airway surgery — when sleep studies confirm obstructive sleep apnea that does not respond to conservative care (e.g., nasal steroids, CPAP).

Preventions & proactive steps

1. Regular endocrine screening (calcium/phosphate/PTH; TSH/free T4) to catch hormone resistance early. Orpha

2. Consistent physiotherapy and home exercise to preserve motion and strength.

3. Healthy-weight plan to reduce joint load and sleep-apnea risk.

4. Adequate calcium/vitamin D intake as advised by your clinicians.

5. Hand-strain reduction (ergonomics, breaks) to prevent overuse injuries and nerve entrapment.

6. Early dental/orthodontic care to prevent caries and bite complications.

7. Sleep-hygiene habits to protect daytime energy, growth, and learning.

8. Infection control (dental/ENT) to avoid flare-ups that worsen breathing or feeding.

9. Home safety and fall prevention to reduce fractures.

10. Genetic counseling for family planning and understanding recurrence risk. PMC

---

When to see doctors (red flags & routine)

• Immediately / urgently: new numbness/tingling/weakness in hands; sudden severe back pain with leg weakness; nighttime breathing pauses or blue spells; fainting; very low calcium symptoms (muscle cramps, tingling around mouth/hands).

• Soon (within days): persistent hand pain or swelling; new snoring with daytime sleepiness; chronic constipation from calcium therapy; behavior or learning regression; dental pain.

• Routine: endocrinology checks every 3–6 months when adjusting therapy; annual physiatry/orthopedics/dentistry/ENT reviews; genetics follow-up when planning a family.

What to eat and what to avoid

What to eat:

1. Calcium-rich foods (milk/yogurt/cheese, fortified alternatives) if your labs indicate need.

2. Vitamin-D sources (fatty fish, fortified foods).

3. Lean proteins (eggs, fish, poultry, beans) to fuel rehab.

4. High-fiber fruits/vegetables to prevent constipation from calcium or binders.

5. Whole grains for steady energy in therapy and school.

What to limit/avoid:

1. Very high-phosphate foods (cola drinks, processed meats) if phosphate runs high.
2. Excess salt (chips, instant noodles) if blood pressure is a concern.
3. Sugary snacks/drinks that promote weight gain and dental problems.
4. Mega-dose supplements that can disturb calcium balance.
5. Alcohol/smoking exposure in teens—harms bone health and sleep.

Frequently asked questions

1. Is Maroteaux–Malamut the same as acrodysostosis?
   Yes—several medical references list Maroteaux–Malamut as a synonym for acrodysostosis. Mount Sinai Health System

2. Is it the same as Maroteaux–Lamy (MPS VI)?
   No. Maroteaux–Lamy is a mucopolysaccharidosis with enzyme deficiency (ARSB) and enzyme-replacement options; acrodysostosis is a bone-growth/hormone-signaling disorder. National Organization for Rare Disorders

3. What genes are involved?
   PRKAR1A and PDE4D. PubMed

4. Who gets hormone resistance?
   It’s more common with PRKAR1A variants (sometimes called “acrodysostosis 1”), but not everyone has it. NCBI

5. Which hormones can be affected?
   Often PTH and TSH; sometimes others that signal via GPCR–cAMP pathways. Oxford Academic

6. Is there a cure?
   No curative drug right now. Care focuses on symptom control, therapies, and timely endocrine treatment. National Organization for Rare DisordersRare Awareness Rare Education Portal

7. Can diet or supplements fix the bone shape?
