RCV000810255 | SCV000950448 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2024-12-24 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 3142 of the BRCA2 protein (p.Asp3142Val). This variant is present in population databases (no rsID available, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 654321). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt BRCA2 protein function with a negative predictive value of 95%. 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 | RCV004949964 | SCV005550131 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-10-01 | criteria provided, single submitter | clinical testing | The p.D3142V variant (also known as c.9425A>T), located in coding exon 24 of the BRCA2 gene, results from an A to T substitution at nucleotide position 9425. The aspartic acid at codon 3142 is replaced by valine, an amino acid with highly dissimilar properties. This amino acid position is not well 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. |
