RCV000546903 | SCV000630609 | uncertain significance | Gastrointestinal stromal tumor | 2023-03-20 | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PDGFRA protein function. ClinVar contains an entry for this variant (Variation ID: 459054). 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 aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 784 of the PDGFRA protein (p.Asp784Tyr). |
Ambry Genetics | RCV002448647 | SCV002733107 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-12-21 | criteria provided, single submitter | clinical testing | The p.D784Y variant (also known as c.2350G>T), located in coding exon 16 of the PDGFRA gene, results from a G to T substitution at nucleotide position 2350. The aspartic acid at codon 784 is replaced by tyrosine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
