SGCA

(redirected from alpha-sarcoglycan)

SGCA

A gene on chromosome 17q21 that encodes a component of the dystrophin-glycoprotein complex, which is thought to be restricted to striated muscle. It stabilises muscle cell membranes and links the actin cytoskeleton to the extracellular matrix.

Molecular pathology
SGCA mutations result in type 2D autosomal recessive limb-girdle muscular dystrophy.

We have had success in the clinic using AAV gene therapy with limb girdle muscular dystrophy type 2D, which is caused by mutations in the alpha-sarcoglycan gene," Louise Rodino-Klapac, PhD, principal investigator in the Center for Gene Therapy at The Research Institute of Nationwide Children's Hospital, said.
However, the dysferlin gene is very large, about six times larger than the alpha-sarcoglycan gene and can't fit into a traditional AAV vector.
The researchers point out that limb-girdle muscular dystrophy actually describes more than 19 disorders that occur because patients have a faulty alpha-sarcoglycan gene.
