Collection Method:clinical testing

The c.631G>A (p.G211R) alteration is located in exon 6 (coding exon 6) of the RRAS gene. This alteration results from a G to A substitution at nucleotide position 631, causing the glycine (G) at amino acid position 211 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 211 of the RRAS protein (p.Gly211Arg). This variant is present in population databases (rs369588682, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RRAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 582576). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
