Loss of function mutations in the DMD gene cause Duchenne muscular dystrophy (DMD), while mutations in the SGCG gene, which encodes the dystrophin associated protein γ-sarcoglycan, cause limb-girdle muscular dystrophy type 2C (LGMD 2C) [2, 3]. The gene discussed is SGCG; the disease is Duchenne muscular dystrophy.
