RCV000707244 | SCV000836334 | uncertain significance | Gastrointestinal stromal tumor | 2019-12-07 | 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PDGFRA-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with isoleucine at codon 184 of the PDGFRA protein (p.Val184Ile). The valine residue is weakly conserved and there is a small physicochemical difference between valine and isoleucine. |
| Ambry Genetics | RCV003303198 | SCV003999032 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-06-05 | criteria provided, single submitter | clinical testing | The p.V184I variant (also known as c.550G>A), located in coding exon 3 of the PDGFRA gene, results from a G to A substitution at nucleotide position 550. The valine at codon 184 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
