This test is a full gene sequencing analysis of the CAV3 (caveolin 3) gene, which has been associated with a group of muscle diseases known as the caveolinopathy.
Pathogenic variants (mutations) in the CAV3 gene can cause five different phenotypes, which can be seen in different members of the same family: 1) Limb-girdle muscular dystrophy 1C (LGMD1C), 2) Isolated hyperCKemia, 3) Rippling muscle disease (RMD), 4) Distal myopathy (DM), and 5) Familial hypertrophic cardiomyopathy (HCM), without skeletal muscle manifestations. LGMD1C can be inherited in either autosomal recessive or autosomal dominant manner, while isolated hyperCKemia, RMD, DM, and Familial HCM phenotypes are typically inherited in autosomal dominant manner.
