autosomal recessive limb-girdle muscular dystrophy type 2W (MONDO_0014788, a Monarch Disease Ontology term) 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. Also known as: LGMD2W, LIMS2 autosomal recessive limb-girdle muscular dystrophy, autosomal recessive limb-girdle muscular dystrophy caused by mutation in LIMS2, muscular dystrophy, autosomal recessive, with cardiomyopathy and triangular tongue, muscular dystrophy, limb-girdle, type 2W, muscular dystrophy, limb-girdle, type 2w.
