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]

Dec 10, 2024

The c.95C>T (p.A32V) alteration is located in exon 3 (coding exon 2) of the RGS19 gene. This alteration results from a C to T substitution at nucleotide position 95, causing the alanine (A) at amino acid position 32 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
