Genes affected

RGS17 (HGNC:14088): (regulator of G protein signaling 17) This gene encodes a member of the regulator of G-protein signaling family. This protein contains a conserved, 120 amino acid motif called the RGS domain and a cysteine-rich region. The protein attenuates the signaling activity of G-proteins by binding to activated, GTP-bound G alpha subunits and acting as a GTPase activating protein (GAP), increasing the rate of conversion of the GTP to GDP. This hydrolysis allows the G alpha subunits to bind G beta/gamma subunit heterodimers, forming inactive G-protein heterotrimers, thereby terminating the signal. [provided by RefSeq, Jul 2008]

The c.415G>A (p.D139N) alteration is located in exon 4 (coding exon 3) of the RGS17 gene. This alteration results from a G to A substitution at nucleotide position 415, causing the aspartic acid (D) at amino acid position 139 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
