Molecular assay reagents intended to identify mutations in the sarcoglycan, beta (43kDa dystrophin-associated glycoprotein) (SGCB) gene, located at chromosome 4q12, which encodes for a member of a multisubunit protein complex that provides structural linkage between the subsarcolemmal cytoskeleton and the extracellular matrix of muscle cells. This inherited genetic mutation has been identified in patients with limb-girdle muscular dystrophy type 2E.
