| Ambry Genetics | RCV000566282 | SCV000661392 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-12-23 | criteria provided, single submitter | clinical testing | The p.V2468E variant (also known as c.7403T>A), located in coding exon 13 of the BRCA2 gene, results from a T to A substitution at nucleotide position 7403. The valine at codon 2468 is replaced by glutamic acid, an amino acid with dissimilar properties. This amino acid position is poorly conserved in available vertebrate species. 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. |

RCV002526776 | SCV003207772 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2022-06-01 | 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) performed at Invitae indicates that this missense variant is not expected to disrupt BRCA2 protein function. ClinVar contains an entry for this variant (Variation ID: 479373). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 2468 of the BRCA2 protein (p.Val2468Glu). |
