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]

Nov 17, 2022

The c.164G>A (p.R55Q) alteration is located in exon 4 (coding exon 3) of the RGS19 gene. This alteration results from a G to A substitution at nucleotide position 164, causing the arginine (R) at amino acid position 55 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
