Sarcoglycanopathies (SGPs) are autosomal recessive limb-girdle muscular dystrophies (LGMDs) caused by mutations in four genes: SGCA, SGCB, SGCG, and SGCD, which lead to α-SGP (LGMDR3), β-SGP (LGMDR4), γ-SGP (LGMDR5), and δ-SGP (LGMDR6), respectively [1]. The gene discussed is SGCB; the disease is sarcoglycanopathy.
