RCV000204715 | SCV000260981 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2023-03-10 | criteria provided, single submitter | clinical testing | This sequence change replaces phenylalanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1978 of the BRCA2 protein (p.Phe1978Val). 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: 220443). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on BRCA2 protein function. 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 | RCV002354580 | SCV002649925 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-10 | criteria provided, single submitter | clinical testing | The p.F1978V variant (also known as c.5932T>G), located in coding exon 10 of the BRCA2 gene, results from a T to G substitution at nucleotide position 5932. The phenylalanine at codon 1978 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
