Mondo Description Autosomal recessive limb-girdle muscular dystrophy type 2W is a subtype of autosomal recessive limb girdle muscular dystrophy characterized by childhood onset of severe, progressive, proximal skeletal muscle weakness and atrophy of the upper and lower limbs with later involvement of distal muscles and development of severe quadraparesis, calf hypertrophy, triangular tongue, and dilated cardiomyopathy. Skeletal muscles undergo diffuse, bilateral, symmetric and severe atrophy with fat infiltration.

Uniprot Description A form of autosomal recessive limb-girdle muscular dystrophy, a degenerative myopathy characterized by slowly progressive wasting and weakness of the proximal muscles of arms and legs around the pelvic or shoulder girdles, elevated creatine kinase levels and dystrophic features on muscle biopsy. LGMD2W is characterized by childhood-onset of weakness progressing to a severe quadriparesis. Additionally, patients have biventricular cardiac dysfunction due to dilated cardiomyopathy.
