Summaries for SGCB Gene

Entrez Gene Summary for SGCB Gene

  • This gene encodes a member of the sarcoglycan family. Sarcoglycans are transmembrane components in the dystrophin-glycoprotein complex which help stabilize the muscle fiber membranes and link the muscle cytoskeleton to the extracellular matrix. Mutations in this gene have been associated with limb-girdle muscular dystrophy.[provided by RefSeq, Oct 2008]

GeneCards Summary for SGCB Gene

SGCB (Sarcoglycan, Beta (43kDa Dystrophin-Associated Glycoprotein)) is a Protein Coding gene. Diseases associated with SGCB include beta-sarcoglycanopathy and muscular dystrophy, limb-girdle, type 2e. Among its related pathways are Hypertrophic cardiomyopathy (HCM) and Hypertrophic cardiomyopathy (HCM).
