Genes affected

RASGRF1 (HGNC:9875): (Ras protein specific guanine nucleotide releasing factor 1) The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) similar to the Saccharomyces cerevisiae CDC25 gene product. Functional analysis has demonstrated that this protein stimulates the dissociation of GDP from RAS protein. The studies of the similar gene in mouse suggested that the Ras-GEF activity of this protein in brain can be activated by Ca2+ influx, muscarinic receptors, and G protein beta-gamma subunit. Mouse studies also indicated that the Ras-GEF signaling pathway mediated by this protein may be important for long-term memory. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Mar 2009]

The c.3785A>G (p.E1262G) alteration is located in exon 28 (coding exon 28) of the RASGRF1 gene. This alteration results from a A to G substitution at nucleotide position 3785, causing the glutamic acid (E) at amino acid position 1262 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
