RCV001057704 | SCV001222208 | uncertain significance | Gastrointestinal stromal tumor | 2021-12-17 | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 852980). This variant has not been reported in the literature in individuals affected with PDGFRA-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 990 of the PDGFRA protein (p.Gly990Ala). |
Ambry Genetics | RCV004031820 | SCV005024547 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-03-13 | criteria provided, single submitter | clinical testing | The p.G990A variant (also known as c.2969G>C), located in coding exon 21 of the PDGFRA gene, results from a G to C substitution at nucleotide position 2969. The glycine at codon 990 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. |
