Sarcoglycanopathies consisting of four subtypes of autosomal recessive limb-girdle muscular dystrophies (LGMD2D, LGMD2E, LGMD2F, and LGMD2C) are caused by biallelic loss-of-function variants in four sarcoglycan genes, including the SGCA, SGCB, SGCD, and SGCG genes encoding the α-, β-, δ-, and γ-sarcoglycan proteins, respectively (1). This evidence concerns the gene SGCG and autosomal recessive limb-girdle muscular dystrophy type 2D.
