Invitae RCV001061654 SCV001226403 uncertain significance Costello syndrome 2019-11-26 criteria provided, single submitter clinical testing 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with HRAS-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with alanine at codon 189 of the HRAS protein (p.Ser189Ala). The serine residue is highly conserved and there is a moderate physicochemical difference between serine and alanine.
