RCV002650555 | SCV002983372 | uncertain significance | Noonan syndrome | 2022-06-22 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 99 of the RRAS protein (p.Arg99Cys). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RRAS-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |
Ambry Genetics | RCV004066774 | SCV003942703 | uncertain significance | not specified | 2023-06-05 | criteria provided, single submitter | clinical testing | The c.295C>T (p.R99C) alteration is located in exon 3 (coding exon 3) of the RRAS gene. This alteration results from a C to T substitution at nucleotide position 295, causing the arginine (R) at amino acid position 99 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
