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.

The c.523A>G (p.I175V) 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 523, causing the isoleucine (I) at amino acid position 175 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
