CAV3 mutations manifest in several human diseases, for example limb girdle muscular dystrophy (LGMD), rippling muscle disease (RMD), hyperCK(creatine kinase)emia, distal myopathy, hypertrophic cardiomyopathy, arrhythmogenic-long-QT syndrome and sudden-infant-death syndrome. Here, CAV3 is linked to limb-girdle muscular dystrophy.
