POMT2-Related Limb-Girdle Muscular Dystrophy

POMT2-related limb-girdle muscular dystrophy is a genetic muscle disease. It slowly weakens the large muscles around the hips and shoulders (the “limb-girdle” muscles). The weakness usually begins in childhood or the teen years and tends to progress over time. The condition happens because changes (variants) in a gene called POMT2 reduce the body’s ability to build a sugar chain on a muscle-anchoring protein called alpha-dystroglycan. Without the right sugar chain, alpha-dystroglycan cannot properly attach muscle cells to the surrounding support structure. As a result, muscles become fragile, break down more easily, and get weaker. This set of disorders is part of a larger family called alpha-dystroglycanopathies, which can range from severe forms in babies to milder limb-girdle forms in older children and adults. In the limb-girdle form linked to POMT2—now formally named LGMDR14—brain and eye involvement is usually absent or mild compared with the severe congenital forms. MedlinePlus+2PubMed+2

POMT2-related limb-girdle muscular dystrophy is a rare, inherited muscle disease caused by harmful variants in the POMT2 gene. POMT2 helps add special sugar chains (O-mannose glycans) onto a muscle-anchoring protein called alpha-dystroglycan. When POMT2 does not work, alpha-dystroglycan is under-glycosylated and cannot firmly connect muscle cells to their support structure outside the cell. Over time, muscles of the hips and shoulders (the “limb girdles”) get weak. Some people also have learning or brain involvement because alpha-dystroglycan is important in brain development, too. The condition is autosomal recessive: a child is affected when both parents pass along a non-working copy. MedlinePlus+2PMC+2

Doctors sometimes group POMT2 disease within the alpha-dystroglycanopathy spectrum, which ranges from severe congenital forms (with brain/eye malformations) to milder limb-girdle forms beginning in childhood. In the LGMDR14/LGMD2N form, children often show slow running, frequent falls, difficulty rising from the floor, calf hypertrophy, and gradually progressive hip/shoulder weakness. Cognitive difficulties can occur more often here than in some other LGMD types. Orpha+1

Other names

You may see several names for the same disorder in clinics, reports, or older papers:

• LGMDR14 (POMT2-related) — the current international name using the “R” (recessive) system. Earlier, it was called LGMD 2N. Cleveland Clinic+1

• POMT2-related alpha-dystroglycanopathy (α-DGP) — emphasizes the sugar-chain (glycosylation) defect on alpha-dystroglycan. PMC

• POMT2-related limb-girdle muscular dystrophy — a descriptive, gene-based label used widely in clinics and papers. PubMed

Your muscles need a stable “anchor” to withstand the stress of daily movement. One part of that anchor is a protein called alpha-dystroglycan that sits on the muscle-cell surface and grabs hold of proteins outside the cell, forming a firm bridge. For alpha-dystroglycan to grab properly, it must be decorated with a special sugar chain (a process called O-mannosyl glycosylation). The enzymes POMT1 and POMT2 work together as a team to start that sugar chain by adding mannose in the endoplasmic reticulum. When POMT2 is faulty, the sugar chain is incomplete, the “grip” is weak, and the muscle membrane gets damaged more easily with activity; over years, this causes progressive weakness. MedlinePlus+1

Types

POMT2 variants can cause a wide spectrum—from very severe infant conditions (like Walker-Warburg syndrome or muscle-eye-brain disease, which involve brain and eye development) to milder limb-girdle forms (LGMDR14) without major brain or eye problems. Where a person falls on this spectrum depends on how much the specific POMT2 changes reduce enzyme function. The limb-girdle form typically presents with childhood slowness in running, frequent falls, and trouble climbing stairs, and may have calf enlargement. Heart problems are uncommon but have been reported in some families. Nature+3PMC+3PubMed+3

Causes

This disease has one primary cause—pathogenic variants in the POMT2 gene—but many different mechanisms and modifiers can shape how severe it becomes and how early it starts. Below are 20 clear “causes” and contributors to disease expression:

1. Pathogenic POMT2 variants (mutations). These are the root cause. They lower or block POMT2 enzyme activity needed to start the mannose sugar chain on alpha-dystroglycan. PubMed

2. Missense variants that partially impair POMT2. One amino acid substitution can reduce—but not eliminate—enzyme function, often leading to a milder, limb-girdle phenotype. ScienceDirect

3. Nonsense or frameshift variants. These can truncate the protein and more strongly reduce function, sometimes pushing toward earlier or more severe disease. ScienceDirect

4. Splice-site variants. These alter RNA splicing and can reduce the amount of correctly made POMT2 protein. ScienceDirect

5. Compound heterozygosity. Many people inherit two different POMT2 variants (one from each parent); the combined effect determines severity. PubMed

6. Complete loss-of-function vs hypomorphic variants. Complete loss tends to cause severe congenital syndromes; hypomorphic (“leaky”) variants more often cause limb-girdle disease. PMC

7. Defective POMT1-POMT2 complex formation. POMT2 works as a complex with POMT1; disrupted pairing reduces O-mannosyltransferase activity. ScienceDirect

8. Downstream glycosylation pathway vulnerability. Even if POMT2 adds the first sugar weakly, later enzymes cannot build a full chain; this amplifies the defect. ScienceDirect

9. Reduced alpha-dystroglycan receptor function. Poor glycosylation lowers alpha-dystroglycan’s binding to proteins like laminin, weakening the muscle “anchor.” PubMed

10. Autosomal recessive inheritance with parental carriers. Disease appears when both gene copies are altered; parents are typically healthy carriers. Cleveland Clinic

11. Founder effects in some populations. Certain communities may share the same historical variant, increasing local frequency. (General alpha-dystroglycanopathy principle.) PubMed

12. Consanguinity (parents related by blood). Increases the chance a child inherits the same variant from both parents. (General genetic principle discussed across LGMD resources.) Muscular Dystrophy Association

13. Muscle mechanical stress over time. Everyday wear on a fragile membrane gradually worsens weakness (a general mechanism in muscular dystrophy). Muscular Dystrophy Association

14. Intercurrent illness and deconditioning. Long periods of inactivity after infections or injuries can speed loss of strength. (General LGMD care principle.) Muscular Dystrophy Association

15. Nutritional insufficiency. Poor protein or calorie intake can reduce muscle maintenance, revealing or worsening weakness. (General LGMD care principle.) Muscular Dystrophy Association

16. Secondary orthopedic changes. Contractures or scoliosis can worsen function even if the underlying muscle strength changes slowly. (LGMD general.) Muscular Dystrophy Association

17. Subtle brain involvement in some α-dystroglycanopathies. While uncommon in LGMDR14, the spectrum includes cases with learning or coordination differences. PMC

18. Rare cardiac involvement. A few families with POMT2 variants have reported heart changes, which may add fatigue or shortness of breath. Nature

19. Variant position within the gene. Some regions are more critical for enzyme function, so variants there cause more severe glycosylation defects. ScienceDirect

20. Other gene modifiers in the glycosylation pathway. Variants in related glycosylation genes might subtly modify severity in some people. ScienceDirect

Common signs and symptoms

1. Hip-girdle weakness. Early difficulty rising from the floor or low chairs, climbing stairs, or running fast; the hips and thighs feel weak first. Muscular Dystrophy Association

2. Shoulder-girdle weakness. Lifting objects overhead, carrying heavy bags, or pushing open heavy doors becomes harder over time. Muscular Dystrophy Association

3. Frequent falls or clumsiness in childhood. Parents may notice slower running and more trips when peers speed up. Orpha

4. Calf enlargement (pseudohypertrophy). Calves may look big because muscle is replaced by fat and scar tissue, not because they are stronger. Orpha

5. Muscle cramps or aching after exertion. Fragile muscle fibers can get irritated easily during or after activity. Muscular Dystrophy Association

6. Fatigue with routine tasks. Dressing, bathing, or walking long distances may take extra effort as the condition progresses. Muscular Dystrophy Association

7. Elevated CK (creatine kinase) on blood tests. A common lab sign of muscle membrane damage, often found even before major weakness. ScienceDirect

8. Gower’s maneuver. Children may push on their thighs with their hands to stand up, using momentum to compensate for weak hip muscles. Muscular Dystrophy Association

9. Tight heel cords and other contractures. Muscles and tendons can stiffen when movement is limited, reducing joint range. Muscular Dystrophy Association

10. Waddling gait. Hip weakness leads to side-to-side trunk motion during walking. Muscular Dystrophy Association

11. Scapular winging. Weak shoulder stabilizers allow the shoulder blades to stick out, especially when pushing the wall. Muscular Dystrophy Association

12. Mild learning differences (uncommon). Most people with LGMDR14 do not have brain malformations, but the larger α-dystroglycanopathy family includes cognition differences in some cases. PMC

13. Rare cardiac findings. Some families with POMT2 variants report heart muscle involvement; screening is advised even if symptoms are absent. Nature

14. Slow overall progression. Compared with congenital forms, limb-girdle POMT2 disease usually progresses slowly. Cleveland Clinic

15. Respiratory weakness late in course (uncommon). As with many LGMDs, breathing muscles can weaken late and may need monitoring. Muscular Dystrophy Association

Diagnostic tests

A) Physical examination (bedside assessment)

1. Manual muscle testing and functional observation. The clinician checks strength group by group and watches tasks (standing from floor, stair climb) to map the limb-girdle pattern. This helps determine severity and track change over time. Muscular Dystrophy Association

2. Gait analysis and posture check. Waddling gait, lumbar lordosis, or scapular winging point to proximal weakness. Gait observation also guides physical therapy plans. Muscular Dystrophy Association

3. Contracture screening. Ankle dorsiflexion, hamstring length, and hip flexor tightness are measured to prevent loss of range with early stretching. Muscular Dystrophy Association

4. Cardiac and respiratory screening exam. Heart sounds, rhythm, and breathing pattern are checked because rare cardiac or later respiratory issues can occur and need early detection. Nature

5. Developmental/cognitive screen (targeted). Usually normal in LGMDR14, but the wider α-dystroglycanopathy spectrum warrants attention if school difficulties appear. PMC

B) Manual and functional tests (standardized measures)

6. Timed motor tests (e.g., 10-meter walk, stair climb). Repeatable, simple tests that quantify movement speed over months and years. Muscular Dystrophy Association

7. Six-minute walk test. Measures endurance and functional exercise capacity in a standardized way. Muscular Dystrophy Association

8. North Star or similar functional scales. Multidomain scores capture gross motor tasks, transfers, and balance to track progression consistently. Muscular Dystrophy Association

9. Hand-held dynamometry. Portable device testing gives objective strength numbers to complement manual muscle testing. Muscular Dystrophy Association

10. Range-of-motion measurements. Serial goniometry helps guide stretching, splinting, and seating plans to avoid fixed contractures. Muscular Dystrophy Association

C) Laboratory and pathological tests

11. Serum creatine kinase (CK). CK is often elevated due to muscle membrane leakiness; high CK can be an early clue even before obvious weakness. ScienceDirect

12. Comprehensive genetic testing. A neuromuscular gene panel or exome testing identifies biallelic POMT2 variants and confirms the diagnosis; carrier testing can be offered to family members. PubMed

13. Muscle biopsy with alpha-dystroglycan immunostaining. If genetics are unclear or unavailable, biopsy can show reduced or altered alpha-dystroglycan glycosylation and dystrophic changes. PMC

14. Pathology for dystrophic changes. The biopsy typically shows fiber size variation, necrosis, and regeneration—supportive but not specific. Genetic confirmation is still needed. Muscular Dystrophy Association

15. Cardiac labs (when indicated). If symptoms or screening suggest cardiac involvement, tests like BNP or troponin may be used with imaging to assess heart muscle stress. Nature

D) Electrodiagnostic tests

16. Electromyography (EMG). EMG usually shows a myopathic pattern (short-duration, low-amplitude motor unit potentials) without nerve damage, supporting a muscle disease rather than neuropathy. Muscular Dystrophy Association

17. Nerve conduction studies (NCS). Typically normal or near-normal; they help exclude primary nerve disorders that mimic weakness. Muscular Dystrophy Association

E) Imaging tests

18. Muscle MRI pattern analysis. MRI can reveal a characteristic distribution of fatty replacement in hip- and shoulder-girdle muscles and can help distinguish α-dystroglycanopathies from other LGMDs. ScienceDirect

19. Brain MRI (selected cases). Usually normal in LGMDR14, but because POMT2 sits on a spectrum including congenital brain involvement, MRI may be done if there are neurological signs or learning issues. American Academy of Neurology

20. Cardiac imaging (echocardiogram or cardiac MRI). Not always required, but reasonable at baseline and periodically, because rare families with POMT2 variants have shown cardiac features. Nature

Non-pharmacological treatments (therapies & other supports)

1) Individualized physiotherapy (PT). A gentle, regular program keeps joints moving and preserves function. PT emphasizes range-of-motion, low-impact aerobic activity, safe strengthening, and contracture prevention—adapted to fatigue and disease stage. Over-exertion that causes prolonged soreness is avoided. PT is a long-term “maintenance” approach, not a cure. PMC

2) Occupational therapy (OT). OT teaches energy conservation, ergonomic strategies, adaptive tools (e.g., long-handled reachers), and safe transfer methods for bathing, dressing, writing, and computer use. It aims to protect joints, reduce falls, and maintain independence at home, school, and work. PMC

3) Orthoses and bracing. Ankle-foot orthoses (AFOs) can improve foot clearance, alignment, and endurance; night splints and hand/wrist splints help prevent contractures. Knee-ankle-foot orthoses (KAFOs) may be considered for posture/ambulation in selected cases. PMC

4) Assistive mobility devices. Canes, forearm crutches, walkers, and manual or power wheelchairs reduce falls, conserve energy, and enable participation in school and community life while lowering fatigue and injury risk. Muscular Dystrophy Association

5) Respiratory monitoring and sleep studies. Regular checks of forced vital capacity (FVC), cough strength, and nocturnal oximetry/capnography detect early hypoventilation or sleep-disordered breathing so that support can start promptly. American Academy of Neurology+1

6) Cough-augmentation therapy (mechanical insufflation–exsufflation). “Cough-assist” devices help clear mucus when cough is weak, lower pneumonia risk, and may reduce hospitalizations—used daily during illness and regularly in advanced weakness. PMC+1

7) Non-invasive ventilation (NIV). Nighttime bilevel ventilation supports breathing muscles, improves sleep quality, morning headaches, and daytime energy, and can be escalated to daytime support if needed. Muscular Dystrophy Association

8) Cardiac surveillance and lifestyle care. Regular ECG/echocardiography screens for cardiomyopathy or rhythm problems seen in some dystroglycanopathies; exercise is tailored; sodium restriction and fluid balance are discussed individually. PMC+1

9) Contracture prevention program. Daily stretching, proper seating, and splinting help avoid fixed joint tightening that restricts motion and worsens function. Early, consistent routines are key. PMC

10) Scoliosis monitoring. Clinical and radiographic follow-up through adolescence identifies curves early; bracing and PT optimize posture; surgical referral is considered if curves progress or impair sitting/breathing. PMC

11) Swallowing/speech therapy. When bulbar muscles are affected, speech-language pathologists guide safe textures, posture, and pacing to reduce choking/aspiration and maintain nutrition. PMC

12) Nutrition optimization. Registered dietitians personalize calories, protein, fiber, and micronutrients; they address constipation, reflux, and weight changes and support bone health with adequate calcium and vitamin D. Muscular Dystrophy Association+1

13) Bone health program. Weight-bearing as tolerated, safe activity, calcium intake goals, vitamin D assessment, and fall-prevention strategies help limit fracture risk in neuromuscular disease. Frontiers

14) Pain management without overuse. Heat, massage, pacing, gentle stretching, and posture correction can relieve overuse pain without relying solely on medications. PMC

15) Education on activity pacing. “Little-and-often” activity with rest breaks prevents post-exertional weakness. Families learn to identify the line between healthy movement and over-fatigue. PMC

16) Infection prevention. Annual influenza and age-appropriate pneumococcal vaccination, early treatment of chest infections, and airway clearance plans reduce respiratory complications. PMC

17) Mental-health and psychosocial support. Counseling, peer groups, and school accommodations support coping, reduce isolation, and improve adherence and quality of life. PMC

18) Genetic counseling. Families receive clear explanations of autosomal recessive inheritance, recurrence risks, and options for carrier testing or future pregnancy planning. PMC

19) Clinical-trial awareness. Because targeted treatments are under study in alpha-dystroglycanopathies, families benefit from reputable registries and research centers. ScienceDirect

20) Peri-operative planning. If surgery is needed (e.g., orthopedic procedures), anesthesia teams plan for respiratory and airway needs; case reports note successful use of TIVA and regional blocks without muscle relaxants in alpha-DG disease. Myja

Drugs Treatment

There are no FDA-approved drugs that specifically modify POMT2-related LGMD. When medicines are used, they usually target complications that can occur in some people (for example, heart failure, arrhythmia, reflux, seizures, infection-related wheeze, or pain). The drugs below are FDA-approved for those problems (labels from accessdata.fda.gov are provided) and may be considered by specialists on a case-by-case basis. They are not cures for POMT2 disease itself. PMC

Heart function (when cardiomyopathy/heart failure is present)

• ACE inhibitor (lisinopril). Helps relax blood vessels and reduce afterload in heart failure. Typical adult dosing is once daily with careful titration; avoid in pregnancy; monitor kidney function and potassium. Common side effects include cough, dizziness, high potassium, and rare angioedema. FDA Access Data

• ARB or ARB combo (losartan / losartan-HCTZ). Used when ACEIs are not tolerated; monitor blood pressure, renal function, and potassium; similar fetal toxicity warning. FDA Access Data+1

• ARNI (sacubitril/valsartan). For chronic heart failure with reduced ejection fraction; requires a washout period after ACEIs to lower angioedema risk. Side effects include hypotension, renal effects, and hyperkalemia. FDA Access Data

• Beta-blockers (carvedilol or metoprolol succinate). Reduce heart workload and improve outcomes in HFrEF; start low and titrate. Watch for bradycardia, fatigue, and dizziness. FDA Access Data+1

• Mineralocorticoid receptor antagonists (eplerenone / spironolactone). Added in HFrEF to improve outcomes; monitor potassium and renal function; avoid potassium supplements. FDA Access Data+1

• Loop diuretic (furosemide or subcutaneous furosemide). Symptom relief for fluid overload (edema, breathlessness); watch electrolytes and kidney function. FDA Access Data+1

Seizure management (if present)

• Levetiracetam (Keppra/XR). Broad-spectrum anti-seizure medicine; titrate dose; watch for mood or behavioral changes. Forms include oral, XR, and IV. FDA Access Data+1

• Diazepam rectal gel (Diastat) or diazepam nasal spray (Valtoco). Rescue treatment for seizure clusters; clear limits exist on frequency of use; sedation is common. FDA Access Data+1

Reflux/GI protection (for dysphagia/GERD)

• Omeprazole (Prilosec / Zegerid formulations). Reduces stomach acid, protects esophagus; dose and formulation individualized; long-term use needs periodic review. FDA Access Data+1

Breathing/airways (symptom relief—not disease-modifying)

• Short-acting bronchodilator (albuterol HFA). Helpful during viral-triggered wheeze or reactive airways; not a core treatment for muscle weakness but may relieve bronchospasm. FDA Access Data+1

Pain/fever (use sparingly and thoughtfully)

• Ibuprofen (including IV ibuprofen, Caldolor). Analgesic/antipyretic; ensure hydration; monitor for GI, renal, or rare skin reactions; IV preparation exists for hospital use. FDA Access Data+1 PMC

Dietary molecular supplements

1) Creatine monohydrate. A well-studied cellular energy buffer. Meta-analyses in muscular dystrophies show small but meaningful strength gains and improved activities of daily living for some patients; typical dosing is a short “load” or steady daily dose (e.g., ~3–5 g/day), with gastrointestinal upset as the most common side effect. This is adjunctive, not curative. PMC+1

2) Coenzyme Q10 (ubiquinone). A mitochondrial cofactor; pilot studies in Duchenne muscular dystrophy suggest modest strength improvements when added to steroids. Dosing varies (often 2–5 mg/kg/day divided); it is generally well tolerated. Evidence is limited and disease-specific benefits in POMT2 are unproven. PMC+1

3) Vitamin D. Supports calcium absorption and bone mineralization; many people with neuromuscular disorders are deficient due to low sun exposure and mobility limits. Typical dietary targets for adults are ~600 IU/day (higher if deficient) with levels monitored and dosing adjusted by a clinician. PMC+1

4) Calcium (diet first, supplement if needed). Helps maintain bone density when combined with vitamin D, weight-bearing as tolerated, and fall-prevention; dietitian-guided intake reduces constipation risk and over-supplementation. Frontiers

5) Omega-3 fatty acids (fish oil). May support general cardiovascular health and have anti-inflammatory effects; dosing commonly 1–2 g/day EPA/DHA combined, adjusted for bleeding risk and procedures. Evidence in LGMD is limited; discuss with clinicians. PMC

6) L-carnitine. A fatty-acid shuttle for mitochondria; sometimes tried for fatigue in neuromuscular disease though evidence is mixed. Typical doses range 1–3 g/day divided; can cause GI upset or fishy odor. PMC

7) Vitamin B12 and folate (if deficient). Correcting deficiencies supports nerve and muscle function; dosing depends on measured levels and cause of deficiency. PMC

8) Magnesium (as needed). Supports muscle and nerve function; supplementation targets documented deficiency or cramps; excess can cause diarrhea. PMC

9) Protein optimization (whey or food-first). Adequate protein supports maintenance of muscle mass; dietitians personalize daily grams to weight, goals, and kidney health. Supplements are considered if diet is insufficient. Muscular Dystrophy Association

10) Antioxidant-rich foods pattern. Emphasizing fruits, vegetables, legumes, nuts, and whole grains supplies antioxidants and micronutrients supporting overall health and recovery from illness, though this does not treat the genetic cause. Muscular Dystrophy Association

Immune/regenerative/stem-cell drug

1) Cell or gene therapy (research stage). For alpha-dystroglycanopathies, gene replacement or editing and substrate-targeted strategies are under study but not yet available as standard care; enrollment in trials should be through reputable centers. ScienceDirect
2) Substrate or pathway modulation. Approaches that enhance alpha-dystroglycan glycosylation have been explored pre-clinically; their role in POMT2 human disease is investigational. ScienceDirect
3) Cardioprotective pharmacotherapy (standard HF drugs). While not regenerative, guideline-directed therapy can protect the heart over time in cardiomyopathy, indirectly preserving function. PMC
4) Bone-strength agents (when indicated). In patients with low bone density and fractures, standard osteoporosis pathways may be considered by specialists after risk–benefit review; this is individualized. Frontiers
5) Immunizations. Vaccines prime adaptive immunity against infections that can worsen respiratory weakness; they prevent complications rather than regenerate muscle. PMC
6) Nutritional optimization. Adequate vitamin D, calcium, and protein support normal tissue turnover; this is supportive biology, not stem-cell therapy. PMC

Surgeries

Orthopedic soft-tissue procedures like Achilles tendon lengthening or hamstring lengthening may improve ankle dorsiflexion or knee extension when contractures limit mobility and braces are insufficient. The goal is easier standing, walking, or seating—not a cure. Myja

Spinal fusion for progressive scoliosis can improve seating balance, comfort, and sometimes breathing mechanics in selected patients with advancing curves, after careful pulmonary and nutrition assessment. PMC

Gastrostomy tube placement is considered if unsafe swallowing causes weight loss or aspiration risk; it supports adequate calories, hydration, and medication delivery. PMC

Airway procedures (e.g., tracheostomy) are rarely needed but may be considered for advanced ventilatory failure when non-invasive methods cannot maintain safety or comfort. PMC

Foot/ankle corrective osteotomies may be discussed for severe deformities that impair bracing, standing, or skin integrity, following comprehensive PT/OT trials. PMC

---

Practical preventions

Daily stretching and posture routines; home fall-proofing; prompt treatment of chest colds; annual flu and pneumococcal shots; balanced nutrition and hydration; pressure-relief cushions and seating checks; weight management to reduce strain; safe activity with rest breaks; regular heart and lung check-ups; and clear emergency plans for breathing problems or seizures. PMC+1

---

When to see doctors urgently or soon

Seek urgent care for new breathing trouble (fast/shallow breathing, morning headaches, daytime sleepiness), chest pain/palpitations, fainting, high fever with thick secretions you cannot clear, choking or repeated aspiration, seizure clusters, or sudden, severe back pain after a fall. Arrange routine visits every 6–12 months with neuromuscular, pulmonary, cardiology, PT/OT, nutrition, and genetics teams, plus eye/learning support as needed. American Academy of Neurology+1

---

What to eat & what to avoid

Favor regular meals rich in lean protein, fruits, vegetables, legumes, whole grains, healthy fats, and calcium-/vitamin-D-containing foods; maintain fiber and fluids for bowel health; use texture modifications if swallowing is unsafe; limit ultra-processed foods high in sodium (heart strain), added sugars (weight gain), and excess saturated fat; avoid high-dose supplements without clinician advice; and tailor plans with a dietitian for growth, weight, and bone goals. Muscular Dystrophy Association+1
