Autosomal recessive limb-girdle muscular dystrophy type 2B (LGMD2B) is a subtype of autosomal recessive limb-girdle muscular dystrophy characterized by an onset in late adolescence or early adulthood of slowly progressive, proximal weakness and atrophy of shoulder and pelvic girdle muscles. Cardiac and respiratory muscles are not involved. Hypertrophy of the calf muscles and highly elevated serum creatine kinase levels are frequently observed. The disease is Monarch Disease Ontology identifier MONDO_0009676 (autosomal recessive limb-girdle muscular dystrophy type 2B). Also known as: DYSF autosomal recessive limb-girdle muscular dystrophy, LGMD2B, LGMD3, autosomal recessive limb-girdle muscular dystrophy caused by mutation in DYSF, limb-girdle muscular dystrophy due to dysferlin deficiency, limb-girdle muscular dystrophy type 2B, limb-girdle muscular dystrophy type 3, muscular dystrophy, limb-girdle, autosomal recessive 2.
