abstract：BACKGROUND:The diagnosis of calpainopathy is obtained by identifying calpain-3 protein deficiency or CAPN3 gene mutations. However, in many patients with limb girdle muscular dystrophy type 2A (LGMD2A), the calpain-3 protein quantity is normal because loss-of-function mutations cause its enzymatic inactivation. The ide...
