The progress of myology over the last decades, in hereditary muscle dystrophies, identified molecular defects in LGMDs, including sarcoglycanopathies, the first of which was gamma-sarcoglycanopathy [3] or LGMD2C, later renamed LGMDR5. This evidence concerns the gene SGCG and autosomal recessive limb-girdle muscular dystrophy type 2C.
