Adhalinopathy

Adhalinopathy is a rare inherited muscle disease caused by a lack or severe shortage of a protein called alpha-sarcoglycan (older name: adhalin). Alpha-sarcoglycan sits on the surface of muscle cells as part of the sarcoglycan complex, which helps the muscle cell membrane stay strong when muscles move. If alpha-sarcoglycan is faulty or missing, the membrane becomes fragile. Over time, normal use of muscles causes tiny tears, the muscle fibers break down, and the body replaces them with fat and scar tissue. This leads to slowly progressive weakness, mainly in the hips, thighs, shoulders, and upper arms (the “limb-girdle” muscles). Many people first notice trouble with running, jumping, climbing stairs, or rising from the floor. The scientific name for this condition is alpha-sarcoglycanopathy, historically called LGMD2D and now re-named LGMDR3 in modern classifications of limb-girdle muscular dystrophy (LGMD). Cardiac and breathing problems are less common than in other sarcoglycan defects but can still occur in some patients, so monitoring is important.

Adhalinopathy is an inherited muscle disease where errors in the SGCA gene (which makes the muscle-membrane protein alpha-sarcoglycan, once called “adhalin”) weaken the “sarcoglycan complex” that stabilizes muscle cells. Weakness usually starts in the hips and shoulders (limb-girdle pattern), often in childhood, and slowly worsens over time. The condition is autosomal recessive (both copies of the gene carry changes). Some people develop tight tendons, calf enlargement, and rarely heart or breathing problems. The term “adhalinopathy” came from early studies that found a marked lack of the 50-kDa “adhalin” protein in muscle; today we call it alpha-sarcoglycanopathy or LGMDR3. Orpha+3American Academy of Neurology+3PubMed+3

Alpha-sarcoglycan sits in the muscle cell’s outer membrane, linked with other sarcoglycans and dystrophin to protect the cell during movement. When alpha-sarcoglycan is missing or faulty, the membrane gets fragile and tears during normal use. That triggers inflammation and slow muscle loss. This shared mechanism explains why different sarcoglycan gene defects cause similar “sarcoglycanopathies.” PMC+1

Other names

Adhalinopathy appears in the literature and clinics under several labels that all refer to the same underlying disorder:

• Alpha-sarcoglycanopathy

• Alpha-sarcoglycan deficiency

• Sarcoglycanopathy (alpha subtype)

• Limb-Girdle Muscular Dystrophy type 2D (LGMD2D) – older term

• Limb-Girdle Muscular Dystrophy, recessive type 3 (LGMDR3) – current term

• SGCA-related LGMD (because the SGCA gene is affected)
  References: ENMC LGMD consensus; OMIM SGCA; Orphanet; MDA.

---

Types

Doctors do not split adhalinopathy into totally different diseases, but they often group patients by how and when symptoms show up and how fast they progress. These “types” help guide care and expectations:

1. By age at first symptoms

• Early-childhood onset: trouble running/jumping in primary school; frequent falls.

• Juvenile onset: sports intolerance appears in late childhood/teens.

• Adult onset: milder course, weakness noticed with heavy work or during military/college fitness tests.
  References: GeneReviews; Orphanet.

2. By severity pattern

• Duchenne-like: early severe hip/thigh weakness, calf enlargement, loss of walking in late childhood/teens (uncommon in alpha-SG but reported).

• Becker-like / intermediate: slower progression; many walk into adulthood.

• Typical limb-girdle: proximal weakness with long-term ambulation.
  References: NORD; clinical case series in sarcoglycanopathies.

3. By genetic change (SGCA variant type)

• Missense (one letter change in DNA → altered protein) often allows some protein function and milder course;

• Nonsense/frameshift (early stop) or splice variants often cause severe deficiency and earlier onset;

• Copy-number deletions/duplications may remove whole exons.
  References: OMIM; GeneReviews; variant databases.

4. By organ involvement

• Skeletal-muscle-predominant: most common;

• With cardiac involvement: less frequent but recognized;

• With respiratory involvement: typically later or in advanced disease.
  References: MDA; Orphanet; cardiology cohorts in LGMD.

Causes

Because adhalinopathy is genetic and autosomal recessive, the root cause is two disease-causing variants in the SGCA gene (one from each parent). Below are 20 concrete “causes or contributors” that either cause the disease directly or shape how it looks and when it appears:

1. Pathogenic SGCA missense variants that reduce alpha-sarcoglycan function but may leave a little protein. References: OMIM; GeneReviews.

2. Nonsense SGCA variants creating early “stop” signals and truncated, non-working protein. References: GeneReviews.

3. Frameshift variants from small insertions/deletions that scramble the protein code. References: GeneReviews; variant databases.

4. Splice-site variants that remove or mix up exons during RNA processing. References: GeneReviews.

5. Exon-level deletions/duplications (copy-number variants) detected by MLPA/NGS CNV tools. References: Orphanet; lab test manuals.

6. Compound heterozygosity (two different harmful SGCA variants, one on each chromosome). References: GeneReviews.

7. Homozygosity for a founder variant in populations with shared ancestry or consanguinity. References: Orphanet; population studies.

8. Protein misfolding with ER degradation—some missense variants make unstable protein that cells destroy. References: muscle biology reviews.

9. Loss of the sarcoglycan complex stability—without alpha-SG, beta/gamma/delta partners mislocalize, weakening the membrane. References: sarcolemma pathophysiology literature.

10. Mechanical membrane fragility during exercise, causing repeated micro-tears and fiber death. References: LGMD pathomechanism reviews.

11. Secondary inflammation that amplifies muscle fiber loss. References: dystrophy immunopathology studies.

12. Inadequate regeneration because satellite cell repair cannot keep up with damage. References: muscle regeneration research.

13. Modifier genes (outside SGCA) that can make disease milder or more severe. References: genetic modifiers in dystrophies.

14. Epigenetic influences that change gene expression and disease onset (under study). References: epigenetics in muscular dystrophy.

15. High mechanical load/overexertion—does not cause disease but may unmask weakness earlier. References: clinical management guidance.

16. Intercurrent illness or prolonged inactivity—deconditioning reveals underlying weakness sooner. References: rehabilitation guidance.

17. Nutritional stress or low vitamin D—won’t cause disease but may worsen fatigue and function. References: supportive-care reviews.

18. Delayed diagnosis with lack of therapy—leads to preventable contractures and faster disability. References: standards of care.

19. Untreated scoliosis/kyphosis—mechanical disadvantage that worsens mobility and breathing. References: LGMD care statements.

20. Unrecognized cardiomyopathy in a subset—can reduce exercise tolerance, add risk. References: cardiology cohorts in LGMD.

Diagnostic tests

A) Physical examination (bedside)

1. General neuromuscular exam – Doctor checks posture, gait, gets up from floor, and looks for Gowers’ sign. Pattern of proximal>distal weakness suggests LGMD rather than nerve disease. References: neuromuscular exam texts; GeneReviews.

2. Functional mobility assessment – Timed stair climb, time to rise from floor, sit-to-stand counts. Shows real-world function and progression. References: rehab/physiotherapy standards.

3. Range of motion and contracture check – Ankles, hips, shoulders. Early stretching can prevent stiffness. References: LGMD care statements.

4. Spine assessment – Look for scoliosis/kyphosis that may affect breathing and comfort. References: rehabilitation guidance.

B) Manual tests (at the bedside or clinic)

5. Manual Muscle Testing (MMT, MRC scale) – Clinician grades muscle strength from 0–5 in hip flexors/extensors, abductors, shoulder abductors, etc., tracking change over time. References: MRC scale guidance.

6. Hand-held dynamometry – Simple device measures force more objectively than MMT for research or clinic follow-up. References: outcome-measure studies in LGMD.

7. Gait analysis / video assessment – Short videos and observational gait analysis detect subtle changes and response to therapy. References: rehab literature.

8. Six-Minute Walk Test (6MWT) – Measures distance walked in six minutes; widely used as an outcome in muscular dystrophies. References: neuromuscular clinical trials.

C) Laboratory and pathological tests

9. Serum creatine kinase (CK) – Usually high (often 5–50× normal) in sarcoglycanopathies; high CK supports muscle breakdown but is not specific. References: GeneReviews; NORD.

10. AST/ALT and LDH – These “liver enzymes” can be elevated from muscle damage, which can mislead unless the clinician knows to check CK and muscle history. References: clinical practice notes.

11. Urine myoglobin (if dark urine after exertion) – Screens for rhabdomyolysis episodes. References: neuromuscular emergency guidance.

12. Genetic testing of the SGCA gene – Core diagnostic test. Modern panels or exome/genome sequencing find missense/nonsense/splice/CNV variants. Confirming two pathogenic variants in SGCA clinches the diagnosis. References: GeneReviews; ACMG testing standards.

13. Muscle biopsy with immunohistochemistry (IHC) – If genetics is unclear or unavailable, a biopsy can show reduced/absent alpha-sarcoglycan staining (often with partial loss of other sarcoglycans) and dystrophic changes. References: pathology atlases; Orphanet.

14. Western blot – Measures amount/size of sarcolemmal proteins; helps when IHC is equivocal. References: pathology methods in muscular dystrophy.

15. Next-generation sequencing CNV analysis / MLPA – Looks for exon deletions/duplications missed by simple sequencing. References: laboratory test manuals; ACMG.

D) Electrodiagnostic and cardiopulmonary tests

16. Electromyography (EMG) – Shows a myopathic pattern (short-duration, low-amplitude motor unit potentials) rather than nerve damage; used if diagnosis is still uncertain. References: EMG textbooks; neuromuscular guidelines.

17. Electrocardiogram (ECG) – Screens for rhythm or conduction problems; baseline and periodic checks advised even though severe heart disease is less common than in beta/delta sarcoglycanopathy. References: cardiology guidelines in dystrophies.

18. Echocardiogram or cardiac MRI – Evaluates heart muscle structure and pumping function; detects early cardiomyopathy when present. References: neuromuscular cardiology statements.

19. Pulmonary function tests (PFTs) – Forced vital capacity (sitting and supine) and cough peak flow; track breathing muscle strength and plan non-invasive ventilation if needed. References: respiratory care standards in NMD.

E) Imaging of skeletal muscle

20. Muscle MRI (thighs/pelvis/shoulder girdle) – Shows characteristic selective fatty replacement patterns that support sarcoglycanopathy and help differentiate from other LGMDs; also useful for choosing biopsy sites.

What to eat (and what to avoid)

Eat: balanced meals with lean proteins, plenty of fruits/vegetables, whole grains, and healthy fats. Spread protein across the day; keep vitamin D/calcium adequate; stay well-hydrated; consider fiber-rich foods to prevent constipation with reduced activity. Avoid/limit: large weight-gain surpluses, highly processed foods, excessive salt (if heart issues), sugary drinks, and alcohol excess, which can worsen balance and muscle recovery. A registered dietitian can tailor plans for growth, adulthood, and steroid use. PMC
