LGMDR1

Chr 15AR

calpain 3

Also known as: CANP3, CANPL3, LGMD2, LGMD2A, LGMDD4, LGMDR1, nCL-1, p94

This gene encodes calpain-3, a muscle-specific calcium-activated cysteine protease that binds to titin and functions as a major intracellular protease in skeletal muscle. Mutations cause limb-girdle muscular dystrophy, autosomal recessive 1 (LGMDR1), which primarily affects the proximal muscles of the shoulders and hips. The condition follows autosomal recessive inheritance.
