Genes affected

DLG5 (HGNC:2904): (discs large MAGUK scaffold protein 5) This gene encodes a member of the family of discs large (DLG) homologs, a subset of the membrane-associated guanylate kinase (MAGUK) superfamily. The MAGUK proteins are composed of a catalytically inactive guanylate kinase domain, in addition to PDZ and SH3 domains, and are thought to function as scaffolding molecules at sites of cell-cell contact. The protein encoded by this gene localizes to the plasma membrane and cytoplasm, and interacts with components of adherens junctions and the cytoskeleton. It is proposed to function in the transmission of extracellular signals to the cytoskeleton and in the maintenance of epithelial cell structure. Alternative splice variants have been described but their biological nature has not been determined. [provided by RefSeq, Jul 2008]

The DLG5 c.268G>C variant is predicted to result in the amino acid substitution p.Gly90Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.013% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-79686011-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
