Ambry Genetics | RCV000775857 | SCV001178168 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-05-16 | criteria provided, single submitter | clinical testing | The p.K351E variant (also known as c.1051A>G), located in coding exon 9 of the BRCA2 gene, results from an A to G substitution at nucleotide position 1051. The lysine at codon 351 is replaced by glutamic acid, an amino acid with similar 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. |

RCV002304219 | SCV002590917 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2022-08-22 | 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: 630465). 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 lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 351 of the BRCA2 protein (p.Lys351Glu). |

RCV005055135 | SCV005689372 | uncertain significance | Breast-ovarian cancer, familial, susceptibility to, 2 | 2024-08-27 | criteria provided, single submitter | clinical testing | The BRCA2 c.1051A>G (p.Lys351Glu) missense variant is absent in gnomAD v2.1.1. The in silico tool BayesDel and splicing algorithm(s) predict a benign effect, but to our knowledge these predictions have not been confirmed by functional studies. To our knowledge, this variant has not been reported in the literature in individuals with hereditary breast and ovarian cancer or Fanconi anemia. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. |
