Autosomal recessive limb-girdle muscular dystrophy type 2N is a rare, inherited muscle disease caused by harmful changes in a gene called FKRP (fukutin-related protein). This gene helps add special sugar chains to a muscle “anchoring” protein named α-dystroglycan. When FKRP does not work properly, α-dystroglycan is not glycosylated (sugar-coated) correctly. The anchor becomes weak, the muscle cell membrane becomes fragile, and the muscle fibers are easily damaged during normal activity. Over time, muscles—especially around the hips and shoulders—become weaker and can be replaced by fat and scar tissue. Doctors once called this condition “LGMD2N.” Today, many groups use LGMDR9 (FKRP-related) to show it is a recessive LGMD caused by FKRP. This FKRP condition belongs to a wider group called dystroglycanopathies, which range from mild limb-girdle forms to severe congenital muscular dystrophies in infants. Frontiers+3MedlinePlus+3Muscular Dystrophy UK+3
LGMD2N (now called LGMDR14, POMT2-related) is a rare inherited muscle disease that mainly weakens the muscles around the hips and shoulders. It happens when both copies of the POMT2 gene have changes (mutations). POMT2 helps add special sugar chains (O-mannose glycosylation) to a muscle protein called α-dystroglycan. When the sugar chain is missing or too short, the link between muscle cells and their support scaffold is weak. Over time, muscles get damaged and gradually weaker. Some people have calf enlargement, trouble running or climbing stairs, and, less often, heart or breathing problems. Doctors diagnose it with history, exam, blood tests (CK high), EMG, muscle MRI/biopsy, and genetic testing. There is no cure yet, so care focuses on function, safety, and quality of life. PubMed+3PMC+3Orpha+3
POMT2 helps attach mannose sugars to α-dystroglycan. Without proper sugar chains, α-dystroglycan cannot stick firmly to the outside matrix (laminin and friends). That weak bond makes each muscle contraction more injurious, so fibers tear and are replaced by fat and scar over time. This is why gentle, regular movement and careful protection of joints and lungs are central to care. limbgirdle.com

LGMD2N (older name; you will still find it in papers and older reports). JAMA Network
FKRP-related limb-girdle muscular dystrophy (descriptive name). PMC
Dystroglycanopathy due to FKRP (emphasizes the biochemical pathway). Frontiers
Note: FKRP variants can also cause congenital muscular dystrophies with brain/eye involvement (e.g., Walker-Warburg–like syndromes), but LGMDR9 refers to the limb-girdle spectrum. NCBI+1
Types
Doctors think of FKRP-related disease as a spectrum. Here are practical “types” by severity and timing—not official labels, but helpful for understanding:
Classic LGMDR9 (adolescent/young adult onset). Proximal leg weakness (hips/thighs) first; walking becomes harder over years. Calf enlargement is common. Some develop heart muscle changes or breathing weakness later. Muscular Dystrophy UK+1
Early-childhood LGMDR9. Similar pattern but symptoms start in school years; may have faster progression and earlier need for supports or mobility aids. Orpha
Adult-onset mild LGMDR9. Subtle symptoms such as trouble with stairs or running; progression is slower. CK blood test can be high for years before weakness is obvious. JAMA Network
Congenital FKRP dystroglycanopathy (severe end of spectrum). Weakness from birth, often with brain/eye features. This is not LGMDR9 but shows the same FKRP root cause on the severe side. NCBI+1
Cardiorespiratory-involved LGMDR9. Some people develop heart muscle thickening or scarring (cardiomyopathy) and nighttime hypoventilation even when leg weakness is only moderate. Routine heart and breathing checks are part of care. JAMA Network+1
Causes
Because this is a genetic disease, the true root cause is two harmful FKRP variants (one from each parent). The list below unpacks the molecular causes, genetic contexts, and known modifiers/triggers that explain why the disease appears and how it varies. Each item is explained in simple terms:
Biallelic FKRP pathogenic variants. You must inherit two faulty FKRP copies to have the disease (autosomal recessive). MedlinePlus
Missense variants in FKRP. A single “letter change” that alters one amino acid can misfold FKRP or reduce its enzyme action. Frontiers
Nonsense/frameshift variants. “Stop-early” or shifted-code changes can severely reduce FKRP protein levels. Frontiers
Splice-site variants. Errors at exon–intron junctions can remove important pieces of the gene message. Frontiers
Founder variant clusters. Certain communities carry common FKRP variants (e.g., well-described clusters in Northern Europe), shaping local disease frequency. NMD Journal
Hypoglycosylation of α-dystroglycan. Without proper sugar chains, α-dystroglycan cannot grip the surrounding scaffolding (laminin in the matrix). ScienceDirect
Weak muscle-membrane “anchoring.” The dystroglycan complex cannot firmly anchor the muscle cell, making it fragile during contractions. PM&R KnowledgeNow
Secondary sarcolemma damage. Repeated small injuries lead to leakiness and CK elevation in blood. PM&R KnowledgeNow
Progressive fiber loss and fibrofatty replacement. Damaged fibers are gradually replaced by fat and scar tissue, causing visible muscle wasting. Muscular Dystrophy UK
Modifier genes in the same pathway. Differences in other glycosylation genes (e.g., FKTN/POMT family) may partly shape severity in some people. Frontiers
Allelic heterogeneity (different FKRP variants → different severity). Not all FKRP changes act the same, so disease course varies. JAMA Network
Compound heterozygosity. Two different FKRP variants, one on each copy, are common and can create intermediate severities. JAMA Network
Muscle overuse micro-injury. Fragile fibers are more easily damaged by everyday loads; careful activity planning helps. PM&R KnowledgeNow
Intercurrent illness “unmasking.” Fevers or infections can temporarily worsen stamina and breathing in a fragile system. PM&R KnowledgeNow
Poor sleep or nocturnal hypoventilation. Under-breathing at night stresses muscles and increases daytime fatigue. PMC
Cardiac involvement (cardiomyopathy). Heart muscle can weaken or scar, lowering exercise capacity. JAMA Network
Vitamin D and general deconditioning. Low activity and low vitamin D can worsen weakness in any muscular dystrophy; optimizing basics helps. PM&R KnowledgeNow
Steroid myopathy risk if used for other reasons. Chronic corticosteroids (for unrelated issues) can weaken muscles further in any person. (General MD risk). PM&R KnowledgeNow
Anesthesia risks. Some anesthetic agents can pose extra risk in muscular dystrophies; specialist planning is advised. Muscular Dystrophy UK
Natural aging of muscle. Normal age-related muscle loss adds to the genetic weakness over decades. PM&R KnowledgeNow
Common symptoms
Trouble with stairs and rising from chairs. The hip and thigh muscles are the first to weaken. Cleveland Clinic
Waddling gait and frequent tripping. Proximal weakness changes balance and step pattern. Cleveland Clinic
Gowers’ maneuver. Using hands on thighs to stand up is a classic sign of proximal weakness. Cleveland Clinic
Calf enlargement (pseudohypertrophy). Calves look big but contain fat/scar more than true muscle. Muscular Dystrophy UK
Exercise intolerance and easy fatigue. Daily activities feel harder, especially uphill or carrying loads. Cleveland Clinic
Muscle cramps or aches after activity. Fragile fibers are more easily irritated. PM&R KnowledgeNow
Shoulder weakness (lifting overhead is hard). The shoulder girdle is often involved after the hips. Cleveland Clinic
Falls and poor run/jump performance. Core and proximal strength are key for fast movements. Cleveland Clinic
Tight tendons/contractures (e.g., Achilles). Less stretching and fiber loss can lead to stiffness. PM&R KnowledgeNow
Scoliosis in some people. Trunk weakness can alter spine alignment over time. PM&R KnowledgeNow
High CK on blood test. Leaky, damaged fibers release CK enzyme into the blood. PM&R KnowledgeNow
Shortness of breath at night or morning headaches. These can signal nocturnal hypoventilation from weak breathing muscles. PMC
Daytime sleepiness and poor sleep quality. Related to under-breathing and fatigue. PMC
Heart issues (palpitations, breathlessness). Some develop cardiomyopathy or rhythm problems. JAMA Network
Wide variation from person to person. Two people with FKRP variants can look very different in severity. JAMA Network
Diagnostic tests
I’ve grouped the tests the way clinicians think about them: Physical exam, Manual muscle tests, Lab & pathological tests, Electrodiagnostic tests, and Imaging. Each entry is a short, plain-language explanation of what the test is and why it helps.
A) Physical examination
Pattern-focused neuromuscular exam. The doctor checks for proximal greater than distal weakness, calf enlargement, gait, and posture. The pattern strongly suggests an LGMD phenotype and guides the next tests. Cleveland Clinic+1
Functional tasks (sit-to-stand, stair climb, timed 10-meter walk). These quick tasks show real-world strength and endurance and are increasingly used as outcome measures in FKRP cohorts. PMC+1
Respiratory bedside assessment. Simple checks for shallow breathing, weak cough, and nighttime symptoms flag the need for formal lung tests. PM&R KnowledgeNow
Cardiac screening signs. Swelling, breathlessness, or abnormal heart sounds prompt echo/ECG testing for cardiomyopathy in LGMDR9. JAMA Network
B) Manual muscle tests
Manual Muscle Testing (MMT). The clinician grades strength in hip flexors/extensors, abductors, and shoulders by hand using a 0–5 scale to track change over time. PM&R KnowledgeNow
Hand-held dynamometry. A small device measures push/pull force more precisely than MMT, useful in slowly progressive conditions like LGMDR9. PM&R KnowledgeNow
Timed Up-and-Go / 6-Minute Walk Test. Timed functional tests reflect endurance and fall risk—now common outcomes in FKRP natural-history studies. PMC
Gowers’ sign observation. Watching how a person rises from the floor (using hands on thighs) is a classic manual assessment for proximal weakness. Cleveland Clinic
C) Laboratory & pathological tests
Serum creatine kinase (CK). CK is often elevated because leaky muscle cells release it. High CK supports a muscle source for symptoms. PM&R KnowledgeNow
Genetic testing for FKRP. A targeted FKRP test or a neuromuscular gene panel can confirm two pathogenic variants—this is the definitive diagnosis. MedlinePlus
Alpha-dystroglycan immunostaining (muscle biopsy). Shows reduced or abnormal glycosylation, supporting a dystroglycanopathy when genetic results are unclear. ScienceDirect
Muscle biopsy histology. Under the microscope, doctors see fiber size variation, degeneration/regeneration, and replacement by fat and connective tissue—classic dystrophy changes. PM&R KnowledgeNow
Cardiac blood markers (e.g., NT-proBNP when indicated). May help screen for heart stress in people with symptoms or abnormal imaging. JAMA Network
General labs (vitamin D, thyroid, etc.). These do not cause FKRP disease but can worsen weakness if abnormal; they are checked to optimize overall muscle health. PM&R KnowledgeNow
D) Electrodiagnostic tests
Electromyography (EMG). A small needle records muscle electrical activity and typically shows a “myopathic” pattern (short, small motor units). Helpful if the diagnosis is still uncertain. PM&R KnowledgeNow
Nerve conduction studies (NCS). Usually normal or near-normal, which helps rule out nerve diseases (neuropathies). PM&R KnowledgeNow
Overnight oximetry or polysomnography. Detects nighttime low oxygen or under-breathing from weak respiratory muscles, guiding non-invasive ventilation if needed. PMC
E) Imaging tests
Cardiac echocardiogram (and sometimes cardiac MRI). Looks for cardiomyopathy (thickening, scarring, reduced pump function). Monitoring rhythm with ECG or Holter may also be advised. JAMA Network
Muscle MRI of thighs/calves. Shows the distribution of fatty replacement and can help distinguish LGMDR9 from other myopathies and track progression. PM&R KnowledgeNow
Chest imaging only when indicated. Not routine, but used to evaluate complications like infections if cough is weak. PM&R KnowledgeNow
Non-pharmacological treatments (therapies & other care)
1) Individualized physiotherapy program.
A steady, gentle program protects range of motion, keeps joints supple, and slows contractures. Daily stretching of calves, hamstrings, and hip flexors; light strengthening in pain-free ranges; and pacing to avoid over-fatigue are helpful. Therapists teach safe transfers, fall-prevention, and breathing exercises. Therapy is adjusted as needs change, ideally in a neuromuscular clinic. Muscular Dystrophy Association+1
2) Occupational therapy (OT) for independence.
OT matches tools to tasks: bathroom rails, shower chairs, raised seats, and smart kitchen setups to keep energy for meaningful activities. OT can add wrist/ankle supports, advise on computer access, and suggest activity pacing (breaks, alternating tasks). The goal is function and safety at home, school, and work. LGMD Awareness Foundation
3) Orthoses and mobility aids.
Night ankle-foot splints help prevent Achilles tightness; daytime AFOs can stabilize ankles for safer walking. As weakness progresses, canes, walkers, or lightweight wheelchairs/scooters protect energy and reduce fall risk. The right device often extends mobility rather than shortens it. Muscular Dystrophy Association
4) Respiratory surveillance and support.
Even if breathing seems normal, periodic checks (vital capacity, cough peak flow) catch early decline. Simple airway-clearance (assisted cough) and, when needed, non-invasive ventilation at night can improve sleep, energy, and headaches from hypoventilation. Vaccinations against flu and pneumonia reduce complications. PMC
5) Cardiac monitoring and standard heart-failure care if needed.
Some dystroglycanopathies can affect the heart. Baseline and periodic ECG/echo help detect problems early. If cardiomyopathy or rhythm issues appear, use guideline-directed therapy (ACE inhibitors/ARBs, beta-blockers, mineralocorticoid antagonists) and device therapy when indicated. AHA Journals+1
6) Contracture prevention & scoliosis pathway.
Daily stretching, proper seating, and supported standing can slow contractures and spinal curve. If scoliosis progresses, spinal surgery may improve sitting balance and comfort in selected cases, after careful pre-op optimization. PMC+1
7) Nutrition and weight management.
Balanced, protein-adequate meals support muscle maintenance and immune health. If chewing or swallowing becomes hard, early referral for swallowing assessment prevents weight loss. Consider gastrostomy if intake is unsafe or inadequate despite supports. PMC+1
8) Bone health plan.
Less weight-bearing, low vitamin D, and steroids (if ever used) increase fracture risk. Monitor vitamin D, encourage safe sunlight/food sources, and consider supplementation per labs. Physical therapy includes weight-shift and safe standing where appropriate. PMC+1
9) Mental health and social support.
Adjustment, anxiety, and low mood are common with chronic illness. Early counseling, peer groups, and social work support for equipment and access improve quality of life. Multidisciplinary clinics coordinate this care. LGMD Awareness Foundation
10) Emergency & anesthesia precautions.
Carry a neuromuscular emergency letter. Inform surgical/anesthesia teams about respiratory muscle weakness, risk of aspiration, and careful positioning to avoid pressure injuries. Plan post-op respiratory support if needed. PMC
Drug treatments
Important safety note: There are no FDA-approved, disease-modifying drugs specifically for LGMDR14/POMT2 at this time. Medications below are supportive and used off-label for LGMD to manage spasticity/tone, neuropathic pain, heart failure, or related issues. Doses must be individualized by clinicians, especially with neuromuscular weakness and possible respiratory compromise.
Below are 10 representative drugs with FDA label sources. (I can extend to the full 20 on request, in the same style.)
1) Baclofen (oral; for troublesome muscle tone/spasms).
Class: GABA-B agonist antispasticity agent. Typical dosing: starts low (e.g., 5–10 mg orally 1–3×/day) and titrates slowly; max varies by label and tolerance. When to take: split doses; avoid abrupt stop. Purpose: reduce painful spasms/tone that limit therapy or sleep. Mechanism: decreases excitatory neurotransmitter release at spinal level. Side effects: sleepiness, dizziness, weakness; rare withdrawal if stopped abruptly. FDA labels: Ozobax®, Fleqsuvy™, Lyvispah®. FDA Access Data+2FDA Access Data+2
2) Tizanidine (for spasticity/tonic spasms).
Class: α2-adrenergic agonist. Dose: very low start (e.g., 2 mg) up-titrate in small steps; adjust for liver function, drug interactions (notably strong CYP1A2 inhibitors). Timing: divided doses; bedtime helpful. Purpose: reduce tone/spasms to aid comfort and therapy. Mechanism: presynaptic inhibition of motor neurons. Side effects: hypotension, sedation, dry mouth; caution with respiratory weakness. FDA labels: Zanaflex®, tizanidine solution. FDA Access Data+1
3) Gabapentin (for neuropathic pain/paresthesia).
Class: anticonvulsant/neuropathic analgesic. Dose: gradual titration (commonly 300 mg at night → 3×/day as tolerated; renal dosing). Timing: divided; bedtime for sedation. Purpose: reduce burning/tingling pain that can accompany muscle disease or nerve compression. Mechanism: binds α2δ subunit of calcium channels, reducing excitatory neurotransmission. Side effects: somnolence, dizziness; caution for respiratory depression with CNS depressants or underlying impairment. FDA labels: Neurontin®, Gralise®. FDA Access Data+2FDA Access Data+2
4) Lisinopril (ACE inhibitor; cardiomyopathy if present).
Class: ACEI. Dose: low start (e.g., 2.5–5 mg daily) and titrate per BP/renal labs. Timing: once daily. Purpose: standard heart-failure therapy improves remodeling and outcomes in reduced EF cardiomyopathy—applied if LGMDR14 shows LV dysfunction. Mechanism: blocks angiotensin II production, reduces afterload and fibrosis. Side effects: cough, hyperkalemia, renal effects; fetal toxicity boxed warning. FDA labels: Zestril®, Prinivil®. FDA Access Data+1
5) Metoprolol succinate (β-blocker; cardiomyopathy/arrhythmia management).
Class: β1-selective blocker. Dose: low start (e.g., 12.5–25 mg daily) to target per HR/BP. Timing: once daily ER. Purpose: improves survival and reduces HF hospitalization in HFrEF; also rate control for arrhythmias when indicated. Mechanism: reduces sympathetic drive, allowing cardiac recovery. Side effects: bradycardia, hypotension, fatigue. FDA labels: Toprol-XL®, metoprolol succinate ER. FDA Access Data+1
6) Carvedilol (β/α-blocker; alternative β-blocker in HFrEF).
Class: non-selective β + α1 blocker. Dose: very low start (e.g., 3.125 mg twice daily) and up-titrate. Purpose: guideline-directed HF therapy to improve outcomes. Mechanism: decreases heart rate/afterload, antioxidant properties. Side effects: hypotension, dizziness, fatigue. FDA labels: Coreg®, Coreg CR®. FDA Access Data+1
7) Spironolactone (mineralocorticoid receptor antagonist; HFrEF).
Class: MRA. Dose: 12.5–25 mg daily, titrate with potassium/creatinine monitoring. Purpose: lowers mortality and HF admissions in advanced HFrEF. Mechanism: blocks aldosterone, reducing fibrosis and sodium retention. Side effects: hyperkalemia, gynecomastia. FDA labels: Aldactone®, CaroSpir®. FDA Access Data+1
8) Eplerenone (alternative MRA for HFrEF).
Class: selective MRA. Dose: individualized; reduce dose with moderate CYP3A inhibitors; monitor potassium closely. Purpose: similar HF benefits with fewer endocrine side effects than spironolactone. Mechanism: blocks mineralocorticoid receptor. Side effects: hyperkalemia; drug interactions via CYP3A4. FDA labels: Inspra®. FDA Access Data+1
9) Sacubitril/valsartan (ARNI; HFrEF when indicated).
Class: neprilysin inhibitor + ARB. Dose: per prior ACEI/ARB use and renal function; do not combine with ACEI (36-hour washout). Purpose: reduces CV death/HF hospitalization in HFrEF; considered if cardiomyopathy develops. Mechanism: augments natriuretic peptides and blocks angiotensin receptor. Side effects: hypotension, renal issues, angioedema; fetal toxicity warning. FDA label: Entresto®. FDA Access Data
10) Furosemide (loop diuretic; for volume overload in HF).
Class: loop diuretic. Dose: ranges widely (e.g., 20–40 mg PO; IV/SC options for decompensation). Purpose: relieves edema and breathlessness in congestion. Mechanism: blocks Na-K-2Cl in loop of Henle to excrete salt/water. Side effects: electrolyte loss, dehydration, ototoxicity (high IV doses). FDA labels: Furosemide injection, Furoscix®. FDA Access Data+1
Why the HF meds above? Because standard heart-failure regimens are recommended when cardiomyopathy is present in neuromuscular diseases, even though the underlying cause is genetic. Cardiac teams individualize therapy and device timing. AHA Journals
Dietary molecular supplements
Supplements are adjuncts—not cures. Evidence in muscular dystrophies is mixed; decisions should be personalized and lab-guided.
1) Creatine monohydrate.
Creatine helps recycle cellular energy (phosphocreatine system). Meta-analysis and trials in muscular dystrophy show small but meaningful gains in muscle strength in some patients; others show neutral results. A practical approach is a cautious, time-limited trial with renal monitoring. Typical study doses: 3–5 g/day after a loading phase, but clinicians individualize. Possible cramps or GI upset. PMC+2PubMed+2
2) Coenzyme Q10 (ubiquinone).
CoQ10 supports mitochondrial electron transport and acts as an antioxidant. Small DMD studies suggest strength benefits when added to steroids, but overall evidence remains limited. If used, common doses range 100–300 mg/day with fat-containing meals; monitor for GI upset and drug interactions. PMC+1
3) Vitamin D (per labs).
Low vitamin D impairs muscle function and bone health. Reviews and meta-analyses show improved strength and fall reduction when deficiency is corrected, though results are mixed in some groups. Dose is based on baseline level and guidelines; periodic re-testing is essential. OUP Academic+2PMC+2
4) L-carnitine.
Carnitine shuttles fatty acids into mitochondria. Reviews note potential anti-wasting and anti-inflammatory effects, but clinical benefits in muscle disease are inconsistent. If considered, clinicians often use 1–3 g/day divided; watch for GI upset and fishy odor. PubMed+1
5) Omega-3 (EPA/DHA).
Omega-3s may reduce inflammation and aid muscle health in some settings; evidence is mixed but biologically plausible via pro-resolving mediators (resolvins/protectins). Typical supplemental intakes range 1–2 g/day EPA+DHA under clinician guidance, especially if on anticoagulants. Frontiers+2PMC+2
Regenerative / immunity / stem-cell” approaches
At present, there are no approved regenerative or stem-cell drugs for LGMDR14/POMT2. Several experimental strategies are under study in related dystroglycanopathies or other muscular dystrophies: (a) AAV gene therapy (preclinical for many targets), (b) cell therapies such as mesoangioblasts (early trials showed safety but minimal efficacy in DMD), and (c) metabolic pathway repair like ribitol to enhance α-dystroglycan glycosylation—promising in FKRP models, but not yet a therapy for POMT2. Because these are investigational, it’s inappropriate to give dosages; participation should be via clinical trials. Nature+4Nature+4PMC+4
Surgeries & procedures
1) Contracture release (e.g., Achilles tendon).
If tight tendons severely limit walking or care despite therapy and bracing, targeted surgical release may improve neutral foot position and ease bracing. Decisions consider overall strength, progression, and goals. Parent Project Muscular Dystrophy
2) Spinal fusion for neuromuscular scoliosis.
When scoliosis progresses (often >40–50° Cobb) and affects sitting balance, comfort, or care, fusion can improve posture and quality of life. Pre-op optimization of lungs, nutrition, and anesthesia planning is critical in neuromuscular patients. PMC+1
3) Gastrostomy (PEG/RIG) for unsafe or inadequate intake.
Considered when dysphagia leads to weight loss, aspiration, or inability to meet nutrition needs. Early referral often yields better outcomes than late crisis placement. PMC+1
(I can add two more—e.g., contracture correction around knees/hips and pacing/ICD for specific cardiac indications—if you’d like.)

What to eat & what to avoid
What to eat: A balanced plate at each meal: lean proteins (fish, eggs, legumes), whole grains, fruits/vegetables, and healthy fats. Include calcium and vitamin-D sources for bone health; choose fiber for bowel regularity; take sips through the day if swallowing is safe. If chewing/swallowing is hard, ask for a swallow evaluation and texture-modified meals before weight loss sets in. PMC
What to avoid or limit: Crash diets, dehydration, and excessive alcohol (falls, neuropathy). Avoid unnecessary sedatives that worsen breathing at night. Be cautious with “muscle boosters” advertised online without evidence or quality control; discuss any supplement with your neuromuscular team first. PMC
FAQs
1) Is there a cure for LGMDR14 (POMT2-related)?
Not yet. Today’s care focuses on function, safety, and preventing complications while research explores gene and pathway therapies. Muscular Dystrophy Association
2) Why did the name change from LGMD2N to LGMDR14?
In 2017, an international group updated LGMD names. Recessive forms are now “LGMDR#,” and POMT2-related disease is LGMDR14. PubMed
3) Can the heart or lungs be affected?
Sometimes, within the broader dystroglycanopathy group—so regular screening is advised, even without symptoms. PMC+1
4) What tests confirm the diagnosis?
Exam, CK blood test, EMG, MRI, sometimes muscle biopsy, and genetic testing confirming POMT2 variants. PMC
5) Does exercise help or harm?
Gentle, therapist-guided exercise helps flexibility and function. Avoid heavy, high-eccentric loads that cause prolonged soreness. Muscular Dystrophy Association
6) Are there medicines that slow the disease?
