Genes affected

SGCD (HGNC:10807): (sarcoglycan delta) The protein encoded by this gene is one of the four known components of the sarcoglycan complex, which is a subcomplex of the dystrophin-glycoprotein complex (DGC). DGC forms a link between the F-actin cytoskeleton and the extracellular matrix. This protein is expressed most abundantly in skeletal and cardiac muscle. Mutations in this gene have been associated with autosomal recessive limb-girdle muscular dystrophy and dilated cardiomyopathy. Alternatively spliced transcript variants encoding distinct isoforms have been observed for this gene. [provided by RefSeq, Jul 2008]

The 193-12G>T variant in SGCD has not been previously reported in individuals wi th cardiomyopathy or in large population studies. This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing, tho ugh this information is not predictive enough to rule out pathogenicity. In summ ary, the clinical significance of the 193-12G>T variant is uncertain. -
