RCV003531251 | SCV004317284 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2024-01-14 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 725 of the BRCA2 protein (p.Lys725Asn). 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. 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 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 | RCV004950458 | SCV005548579 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-07-24 | criteria provided, single submitter | clinical testing | The p.K725N variant (also known as c.2175A>C), located in coding exon 10 of the BRCA2 gene, results from an A to C substitution at nucleotide position 2175. The lysine at codon 725 is replaced by asparagine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |
