Living with Autosomal recessive limb-girdle muscular dystrophy type 2W

An inherited muscle condition with severe weakness that begins in childhood and affects the heart.

Understanding Autosomal recessive limb-girdle muscular dystrophy type 2W

Autosomal recessive limb-girdle muscular dystrophy type 2W is an inherited muscle condition with severe weakness that starts in childhood.

Weakness and wasting start near the center of the arms and legs, then reach muscles farther out. It can lead to severe weakness of all four limbs. Calves can be enlarged, the tongue can be triangular, and the heart muscle can be enlarged and weak (dilated cardiomyopathy).

Signs & symptoms

GARD doesn't list specific symptoms for this condition. The summary describes these features:

  • Severe weakness near the center of the limbs
  • Later weakness in hands and feet
  • Muscle wasting with fat replacement
  • Enlarged calf muscles
  • Triangular tongue
  • Heart muscle disease (dilated cardiomyopathy)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
