SGCA and sarcoglycanopathy: Sarcoglycanopathies (SG) are the most frequent form of autosomal recessive LGMD comprising of four subtypes, LGMDR3, LGMDR4, LGMDR5, and LGMDR6, caused by mutations in SGCA, SGCB, SGCG, and SGCD encoding for the alpha-, beta-, delta-, and gamma-sarcoglycan proteins, respectively [1].
