Genes affected

RGS19 (HGNC:13735): (regulator of G protein signaling 19) G proteins mediate a number of cellular processes. The protein encoded by this gene belongs to the RGS (regulators of G-protein signaling) family and specifically interacts with G protein, GAI3. This protein is a guanosine triphosphatase-activating protein that functions to down-regulate Galpha i/Galpha q-linked signaling. Alternatively spliced transcript variants encoding the same protein isoform have been found for this gene. [provided by RefSeq, Jul 2008]

The c.498C>G (p.N166K) alteration is located in exon 6 (coding exon 5) of the RGS19 gene. This alteration results from a C to G substitution at nucleotide position 498, causing the asparagine (N) at amino acid position 166 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
