RCV000819432 | SCV000960091 | uncertain significance | Gastrointestinal stromal tumor | 2018-12-21 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with arginine at codon 741 of the PDGFRA protein (p.Gln741Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. This variant is present in population databases (rs141704268, ExAC 0.01%). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, 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 PDGFRA-related conditions. |
