p94, a muscle-specific member of the calpain family, also called calpain3 (CAPN3), has been identified as the gene product responsible for limb-girdle muscular dystrophy type 2A (LGMD2A). To elucidate the molecular mechanism of LGMD2A, the effects of missense point mutations found in LGMD2A on the unique properties of p94 were studied. All of the mutants examined to date lose their proteolytic activity against fodrin, a cytoskeletal protein, strongly suggesting that of the specific properties of p94, the loss of protease activity is the prime cause of LGMD2A. Studies of LGMD2A and p94 suggest a novel molecular mechanism for muscular dystrophy, showing that a combined pathologic and biochemical approach is effective.
