SGCD (Delta-sarcoglycan) variants and mutations

SGCD (also known as Delta-sarcoglycan) is a human protein-coding gene encoding a delta-sarcoglycan protein. Delta-sarcoglycan is part of the dystrophin-associated complex that links the muscle-cell cytoskeleton to the extracellular matrix. Variants can cause limb-girdle muscular dystrophy and cardiomyopathy. This analysis covers 614 SGCD variants and mutations. Of these, 94% have computational variant effect predictions. Disease context includes autosomal recessive limb-girdle muscular dystrophy type 2F, dilated cardiomyopathy 1L, and autosomal recessive limb-girdle muscular dystrophy. Example SGCD variants include P2A, P2L, and P2S.
