Severe Childhood Autosomal Recessive Muscular Dystrophy, North African Type

Severe childhood autosomal recessive muscular dystrophy, North African type, is a genetic muscle disease that usually starts in early childhood. It makes the muscles around the hips and shoulders weak first, then slowly involves many other muscles. The condition is autosomal recessive, which means a child becomes sick when they receive a changed (mutated) copy of the same gene from both parents. This disorder is strongly linked to North African families because of a common “founder” mutation that arose in that region and was passed down through generations. The medical cause is usually a harmful change in the SGCG gene, which makes a protein called gamma-sarcoglycan. Gamma-sarcoglycan is part of a team of proteins (the sarcoglycan complex, within the larger dystrophin-associated glycoprotein complex) that protects the muscle cell membrane during movement. When gamma-sarcoglycan is missing or not working, the muscle cell membrane becomes fragile, muscle fibers get damaged with normal use, and progressive muscle weakness follows. The illness can look “Duchenne-like” (rapid and severe) even though it comes from a different gene. Science+2PMC+2

Another names

• Gamma-sarcoglycan–related limb-girdle muscular dystrophy

• LGMD2C (older name), now LGMDR5 (new naming)

• γ-sarcoglycanopathy

• Sarcoglycanopathy (gamma type)

• Duchenne-like muscular dystrophy, autosomal recessive

• Severe autosomal recessive muscular dystrophy of childhood—North African type
  These names all point to muscle weakness caused by SGCG (gamma-sarcoglycan) gene variants, with a frequent North African founder mutation (c.525delT). PMC+3Orpha+3ScienceDirect+3

Types

Doctors place this condition inside the sarcoglycanopathies—a family of muscle diseases caused by faults in four sarcoglycan genes:

1. LGMDR3 (α-sarcoglycan / SGCA)

2. LGMDR4 (β-sarcoglycan / SGCB)

3. LGMDR5 (γ-sarcoglycan / SGCG) ← the North African type usually sits here

4. LGMDR6 (δ-sarcoglycan / SGCD)

All four proteins join to form the sarcoglycan complex. When one is missing (for example, gamma-sarcoglycan in LGMDR5), the whole complex can become unstable, leading to muscle damage. Severity varies, but gamma-sarcoglycan deficiency often causes a childhood-onset, fast-progressing pattern. PubMed+2PMC+2

Multiple studies show that a single letter deletion, called c.525delT in SGCG, is especially common in Morocco, Tunisia, Algeria, and neighboring regions. Because many affected families carry this same change from a common ancestor (founder effect), the illness appears more often there, and often with severe, Duchenne-like weakness beginning in childhood.

Causes

1. Pathogenic SGCG mutations (core cause).
   Harmful changes in the SGCG gene reduce or eliminate gamma-sarcoglycan. Without this membrane protein, muscle fibers are easily injured by normal movement, leading to chronic damage and weakness. Science+1

2. Founder variant c.525delT (common in North Africa).
   This tiny deletion shifts the gene “reading frame,” producing a nonfunctional protein, which strongly drives the severe childhood form. PMC

3. Other SGCG loss-of-function variants.
   Nonsense, frameshift, and splice-site mutations can also stop the protein from being made correctly, causing similar disease. ScienceDirect

4. Missense variants in critical domains.
   Single-letter changes that alter important amino acids can deform the protein’s structure and prevent it from joining the sarcoglycan complex. PMC

5. Complex destabilization of the sarcoglycan complex.
   When gamma-sarcoglycan is absent, the α/β/δ subunits may also be reduced at the membrane, compounding weakness. PMC

6. Secondary membrane fragility.
   The sarcoglycan complex links to dystrophin. Without it, the membrane tears during contraction, letting calcium rush in and damaging fibers. PMC

7. Repeated contraction injury.
   Daily activity repeatedly injures fragile fibers, causing inflammation and scarring (fibrosis) over years. PMC

8. Modifier genes.
   Differences in other muscle-related genes can modify how early or severe the weakness becomes, even within the same family. (Inference consistent with variability across sarcoglycanopathies.) BioMed Central

9. Inflammatory pathways.
   Muscle damage triggers inflammation, which can further harm muscle if it becomes chronic. PMC

10. Fibrosis and fatty replacement.
    Over time, damaged muscle is replaced by fat and scar tissue, reducing strength and flexibility. PMC

11. Oxidative stress.
    Membrane injury and inflammation increase reactive oxygen species, which worsen muscle damage. PMC

12. Impaired signaling at the membrane.
    The dystrophin-associated complex also hosts signaling proteins; disruption may blunt normal growth/repair signals. PMC

13. Cardiac muscle involvement.
    Some patients develop heart muscle changes, contributing to fatigue and breathlessness. Severity varies. ScienceDirect

14. Respiratory compromise.
    Weak diaphragm and chest muscles make breathing less efficient, especially later in the disease. ScienceDirect

15. Contractures due to immobility.
    Weak muscles and tight tendons lead to joint stiffness, which in turn limits movement and increases disability. ScienceDirect

16. Scoliosis from muscle imbalance.
    Weak trunk muscles allow spinal curvature to develop, particularly after loss of walking ability. ScienceDirect

17. Nutritional factors (secondary, not primary cause).
    Poor intake due to fatigue or swallowing difficulty can worsen weakness but does not cause the disease itself. (General LGMD care principle.) ScienceDirect

18. Infections (secondary stressor).
    Respiratory infections can unmask or aggravate breathing muscle weakness. ScienceDirect

19. Delayed diagnosis (care gap).
    Late recognition delays physical therapy, respiratory monitoring, and supportive devices, allowing preventable complications. ScienceDirect

20. Limited access to specialized care (contextual factor).
    In regions with fewer neuromuscular centers, patients may miss genetic testing and tailored management that can slow complications. (Public health observation consistent with regional reports.) MDPI

Symptoms

1. Early hip and thigh weakness.
   Trouble running, jumping, or climbing stairs appears first because hip and thigh muscles are affected early. Orpha

2. Shoulder weakness.
   Lifting arms overhead becomes hard; children may struggle with hair washing or putting on shirts. Orpha

3. Gowers’ sign (using hands to rise).
   To stand up from the floor, a child “walks up” their legs with the hands due to weak hip muscles. Orpha

4. Frequent falls and fatigue.
   Weak hips and shoulders reduce balance and endurance. Orpha

5. Calf enlargement (pseudohypertrophy).
   Calves may look big due to fat and scar tissue replacing muscle. Orpha

6. Toe-walking or waddling gait.
   Weak pelvic muscles cause a side-to-side sway or toe-walking to compensate. Orpha

7. Loss of walking (often in adolescence).
   Progressive weakness can lead to wheelchair use; timing varies, but the “severe childhood” form progresses faster. Orpha

8. Joint contractures.
   Ankles, knees, or elbows can stiffen over time, limiting movement and making care harder. ScienceDirect

9. Scoliosis.
   Spinal curvature can appear as trunk muscles weaken, especially after loss of walking. ScienceDirect

10. Breathing problems.
    Shallow breathing at night, morning headaches, or daytime sleepiness may signal weak breathing muscles. ScienceDirect

11. Respiratory infections.
    Cough becomes weak, making it hard to clear mucus, which increases infection risk. ScienceDirect

12. Possible heart involvement.
    Some have cardiomyopathy or rhythm issues; screening is needed even if symptoms are mild. ScienceDirect

13. Muscle pain or cramps after activity.
    Fragile muscle fibers can become sore after use. ScienceDirect

14. Swallowing fatigue (late).
    Bulbar muscle involvement is less prominent than in some other dystrophies but can appear later. ScienceDirect

15. Psychosocial stress.
    Children and families may face anxiety, school challenges, and social barriers; multidisciplinary support helps. MDPI

Diagnostic tests

A) Physical examination

1. General muscle strength testing.
   A clinician checks each muscle group (hips, shoulders, neck, trunk) against gentle resistance. A typical pattern shows weaker hip and shoulder muscles first. This bedside assessment guides which lab and imaging tests to do next. Orpha

2. Gait and function observation.
   Doctors watch walking, stair climbing, standing from the floor, and arm raising. Waddling gait and Gowers’ sign suggest limb-girdle weakness. Orpha

3. Joint range and contracture check.
   They measure ankles, knees, hips, and elbows for tightness. Early stretching programs depend on these measurements. ScienceDirect

4. Spine assessment.
   The back is inspected for curves (scoliosis) that can worsen breathing mechanics if not managed. ScienceDirect

5. Respiratory and cardiac screening.
   Chest movement, breathing rate, and heart sounds are reviewed because lungs and heart can be affected in sarcoglycanopathies. ScienceDirect

B) Manual / bedside functional tests

6. Timed function tests (TFTs).
   Time to stand from the floor, time to climb four stairs, or to walk a set distance helps track progression and treatment impact in clinics. ScienceDirect

7. Six-minute walk test (6MWT).
   Measures how far a person can walk in six minutes. It reflects endurance, gait stability, and respiratory cooperation. ScienceDirect

8. North Star–style scales / motor scales adapted to LGMD.
   Structured checklists score standing, walking, running, and hopping. Scores help compare across visits. ScienceDirect

9. Manual muscle testing (MMT).
   Graded 0–5, this checks individual muscle strength. It is simple and repeatable, especially where advanced equipment is limited. ScienceDirect

C) Laboratory and pathological tests

10. Blood creatine kinase (CK).
    CK leaks from injured muscle into blood and is high in active muscle breakdown. High CK suggests a dystrophy and supports further genetic testing. ScienceDirect

11. Genetic testing—targeted SGCG analysis.
    When the clinical picture fits, labs check SGCG first (especially in North African ancestry) for c.525delT and other known variants. This is the definitive test. NCBI+1

12. Next-generation sequencing panels.
    If SGCG testing is negative or uncertain, a broader LGMD gene panel can find rarer variants or rule in other sarcoglycan genes. ScienceDirect

13. Muscle biopsy with immunohistochemistry (IHC).
    A small piece of muscle is examined to show loss of gamma-sarcoglycan and often reduced other sarcoglycans. IHC patterns can guide which gene to test. BioMed Central

14. Western blot for sarcoglycans.
    This test measures the amount/size of sarcoglycan proteins and can confirm a deficiency pattern typical of LGMDR5. BioMed Central

15. Cardiac blood markers (when indicated).
    If symptoms suggest heart strain, troponin/BNP may support the need for cardiology imaging and monitoring. (Supportive practice in muscular dystrophies.) ScienceDirect

D) Electrodiagnostic tests

16. Electromyography (EMG).
    Fine needle electrodes record muscle activity. A myopathic pattern (small, brief motor units) supports a primary muscle disease rather than a nerve problem. ScienceDirect

17. Nerve conduction studies (NCS).
    Usually normal in muscular dystrophy. This helps exclude neuropathies, focusing attention on muscle-based causes. ScienceDirect

E) Imaging tests

18. Muscle MRI (preferred).
    MRI shows which muscles are being replaced by fat and scar tissue. Certain patterns (pelvic and shoulder girdle) support sarcoglycanopathy and help choose a biopsy site if needed. ScienceDirect

19. Echocardiogram and/or cardiac MRI.
    Screens for cardiomyopathy or rhythm-related heart muscle changes that may come with some sarcoglycan defects. ScienceDirect

20. Pulmonary function tests and sleep studies.
    Measures breath strength (FVC, MIP/MEP) and checks for night-time hypoventilation; guides timing of non-invasive ventilation. ScienceDirect

Non-pharmacological treatments

1. Regular, gentle physiotherapy & stretching.
   Purpose: keep joints flexible, delay contractures, and preserve standing/transfer skills. Mechanism: low-intensity range-of-motion and posture programs prevent tightening of tendons and connective tissue; over-exertion is avoided to reduce membrane injury. PMC+1

2. Night splints, orthoses, and seating support.
   Purpose: maintain ankle/foot position, slow contractures, improve sitting balance, and reduce energy cost of movement. Mechanism: sustained gentle positioning minimizes muscle-tendon shortening and improves leverage for remaining muscle. PM&R KnowledgeNow

3. Assisted cough and airway-clearance training.
   Purpose: reduce chest infections and hospitalizations. Mechanism: manual-assisted cough, mechanical insufflation-exsufflation, and lung-volume recruitment increase expiratory flow and clear secretions when cough is weak. Creighton University+1

4. Sleep and breathing support (NIV).
   Purpose: treat night hypoventilation, improve daytime alertness, and protect the heart/lungs. Mechanism: non-invasive ventilation unloads weak breathing muscles and normalizes CO₂/O₂, guided by periodic pulmonary function tests. Chest Journal+1

5. Cardiac surveillance with early heart-failure care.
   Purpose: detect silent heart changes and start therapy early. Mechanism: baseline and periodic ECG, echo, and cardiac MRI to track fibrosis and function, then apply standard pediatric cardiomyopathy care when indicated. AHAS Journals

6. Bone-health program.
   Purpose: prevent fractures and spine deformity, especially if steroids are used or mobility is reduced. Mechanism: vitamin D and calcium sufficiency, fall-prevention, and periodic spine checks; clinicians consider bisphosphonates for osteoporosis per guidelines. PMC+1

7. Scoliosis monitoring and timely referral.
   Purpose: keep sitting balance, ease caregiving, and protect lung function. Mechanism: regular spinal X-ray review; if curves progress, discuss spinal fusion at experienced centers mindful of higher anesthesia/respiratory risks in neuromuscular disease. PMC+1

8. Adaptive equipment & energy conservation.
   Purpose: preserve independence in school/home. Mechanism: wheelchairs, walkers, transfer aids, and occupational-therapy strategies reduce muscle strain and fatigue while supporting safe mobility. Muscular Dystrophy Association

9. Genetic counseling for family planning.
   Purpose: explain risks to siblings and future children and options for carrier testing/prenatal diagnosis. Mechanism: autosomal-recessive inheritance counseling once the SGCG variant is identified. Orpha

10. Clinical-trial awareness.
    Purpose: consider research options (e.g., gene therapy SRP-9005) at specialized centers. Mechanism: families can review eligibility and risks as programs open (first-in-human studies just cleared in 2025). Muscular Dystrophy News+1

Dietary molecular supplements

1. Creatine monohydrate.
   Dose often used in studies: ~0.1 g/kg/day after loading; ask your team. Function/mechanism: increases muscle phosphocreatine energy buffer; several trials in muscular dystrophies show small but meaningful strength gains and good tolerance. PMC+1

2. Coenzyme Q10 (ubiquinone).
   Dose: variable (e.g., 2–8 mg/kg/day in studies). Function: mitochondrial electron-transport cofactor and antioxidant; pilot trials added to steroids in DMD showed ~8.5% strength improvement; evidence is limited but suggestive. PMC+1

3. Vitamin D3 with Calcium.
   Dose: individualized to reach normal 25-OH vitamin D levels (often 800–2000 IU/day; pediatric dosing varies). Function: builds bone, combats steroid-related bone loss; strongly recommended in steroid-treated neuromuscular disease. PMC+1

4. L-carnitine.
   Dose: variable (e.g., 50–100 mg/kg/day divided); Function: supports fatty-acid transport into mitochondria; small studies suggest fatigue benefit, but evidence is modest. Discuss with your clinician. Parent Project Muscular Dystrophy

5. Omega-3 fatty acids.
   Dose: per cardiology/nutrition guidance. Function: anti-inflammatory, may support cardiac health in chronic disease; evidence in muscular dystrophy is preliminary. AHAS Journals

6. Antioxidant blends (e.g., vitamin E/C) under supervision.

Immunity booster / regenerative / stem-cell drugs

There are no FDA-approved immune-boosting or stem-cell drugs for gamma-sarcoglycanopathy. Experimental approaches include mesoangioblast/pericyte cell therapy and AAV-based gene therapy (e.g., SRP-9005 for SGCG), which have shown promising preclinical results and only recently received FDA clearance for first-in-human trials. These are research treatments and are available only in clinical trials with strict safety oversight. SpringerLink+2PMC+2

Surgeries

1. Posterior spinal fusion for progressive scoliosis.
   Why it’s done: to improve sitting balance, comfort, and pulmonary mechanics when curves progress despite conservative care. Notes: neuromuscular scoliosis surgery can reduce progression but carries higher respiratory risks—centers with neuromuscular expertise are preferred. MDPI+1

2. Soft-tissue contracture releases (e.g., Achilles lengthening).
   Why: to achieve plantigrade feet, improve bracing/standing, and ease caregiving when conservative measures fail. PMC+1

3. Cardiac device therapy in selected patients (ICD/pacemaker).
   Why: to treat significant arrhythmias or conduction disease if they occur, per neuromuscular cardiology guidance. Physiopedia

What to eat (and avoid) in simple terms

Eat: balanced meals with adequate protein, fruits/vegetables, and calcium-/vitamin D–rich foods to protect bones, plus enough fluids/fiber to prevent constipation (common with lower mobility or opioids if used). Avoid/limit: ultra-processed, very salty foods (can worsen fluid retention with heart meds), excess sugar, and megadose supplements without labs and medical advice (vitamin D can be harmful if overused). Work with a neuromuscular dietitian. PMC+1

Frequently asked questions

1. Is this the same as Duchenne?
   No. Symptoms can look similar, but Duchenne is from dystrophin gene mutations and is X-linked; LGMDR5 is from SGCG and is autosomal recessive. Orpha

2. Why is it common in North Africa?
   A single ancestral SGCG deletion spread in that population (a “founder mutation”). PMC

3. Can it affect the heart and breathing?
   Yes—both need regular checks and timely therapy. PubMed

4. Is there a cure?
   Not yet. Supportive care helps; gene therapy for SGCG just entered first-in-human testing. Muscular Dystrophy News

5. Will exercise help or harm?
   Gentle, low-impact movement helps flexibility and function; avoid high-intensity, eccentric overload that can injure fragile muscle. Follow a physiotherapist’s plan. PMC

6. Should we use steroids?

7. What about heart medicines?
   ACE-I, beta-blockers, MRAs are standard for cardiomyopathy and are often used by extrapolation in LGMDR5 with cardiology oversight. AHAS Journals+1

8. Do supplements work?
   Creatine and CoQ10 show small benefits in trials of muscular dystrophy; vitamin D/calcium protect bones—always personalize dosing and monitor. PMC+1

9. How is the diagnosis confirmed?
   By genetic testing for an SGCG pathogenic variant. PMC

10. Can siblings be tested?
    Yes—after a family variant is known, carrier and predictive testing can be discussed. Orpha

11. Will surgery be necessary?
    Sometimes for scoliosis or severe contractures; decisions are individualized at expert centers. MDPI

12. Is night ventilation common?
    It’s considered when tests show hypoventilation or symptoms appear; it improves sleep and daytime energy. Chest Journal
