RCV000707621 | SCV000836722 | uncertain significance | Gastrointestinal stromal tumor | 2024-01-26 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 577 of the PDGFRA protein (p.Pro577Leu). This variant is present in population databases (rs778015444, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with PDGFRA-related conditions. ClinVar contains an entry for this variant (Variation ID: 583318). 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. 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. |
| Ambry Genetics | RCV001012885 | SCV001173399 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-09-18 | criteria provided, single submitter | clinical testing | The p.P577L variant (also known as c.1730C>T), located in coding exon 11 of the PDGFRA gene, results from a C to T substitution at nucleotide position 1730. The proline at codon 577 is replaced by leucine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |
