Labcorp Genetics (formerly Invitae), Labcorp RCV001904467 SCV002119789 uncertain significance Noonan syndrome 2020-12-11 criteria provided, single submitter clinical testing This sequence change replaces valine with alanine at codon 33 of the RRAS protein (p.Val33Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RRAS-related conditions. This variant is not present in population databases (ExAC no frequency).
