| Ambry Genetics | RCV000561349 | SCV000668770 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-03 | criteria provided, single submitter | clinical testing | The p.P2477S variant (also known as c.7429C>T), located in coding exon 13 of the BRCA2 gene, results from a C to T substitution at nucleotide position 7429. The proline at codon 2477 is replaced by serine, an amino acid with similar properties. This amino acid position is not well 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. |

RCV001303074 | SCV001492308 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2024-11-24 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2477 of the BRCA2 protein (p.Pro2477Ser). This variant is not present in population databases (gnomAD no frequency). 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: 52325). 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. |
