Genes affected

RASGRF2 (HGNC:9876): (Ras protein specific guanine nucleotide releasing factor 2) RAS GTPases cycle between an inactive GDP-bound state and an active GTP-bound state. This gene encodes a calcium-regulated nucleotide exchange factor activating both RAS and RAS-related protein, RAC1, through the exchange of bound GDP for GTP, thereby, coordinating the signaling of distinct mitogen-activated protein kinase pathways.

Sep 14, 2023

The c.1721A>G (p.Q574R) alteration is located in exon 1 (coding exon 1) of the RASGRF2 gene. This alteration results from a A to G substitution at nucleotide position 1721, causing the glutamine (Q) at amino acid position 574 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
