RCV001938821 | SCV002202387 | uncertain significance | Gastrointestinal stromal tumor | 2020-12-12 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with glycine at codon 585 of the PDGFRA protein (p.Arg585Gly). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and glycine. 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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 C15"). This variant has not been reported in the literature in individuals with PDGFRA-related conditions. This variant is not present in population databases (ExAC no frequency). |
