Genes affected

RGS3 (HGNC:9999): (regulator of G protein signaling 3) This gene encodes a member of the regulator of G-protein signaling (RGS) family. This protein is a GTPase-activating protein that inhibits G-protein-mediated signal transduction. Alternative splicing and the use of alternative promoters results in multiple transcript variants encoding different isoforms. Long isoforms are largely cytosolic and plasma membrane-associated with a function in Wnt signaling and in the epithelial mesenchymal transition, while shorter N-terminally-truncated isoforms can be nuclear.

The c.733C>T (p.L245F) alteration is located in exon 9 (coding exon 8) of the RGS3 gene. This alteration results from a C to T substitution at nucleotide position 733, causing the leucine (L) at amino acid position 245 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
