RCV001971462 | SCV002258960 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2023-01-13 | criteria provided, single submitter | clinical testing | 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: 1477176). 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. 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. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 1659 of the BRCA2 protein (p.Ser1659Phe). |
Ambry Genetics | RCV002335003 | SCV002643990 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-08-18 | criteria provided, single submitter | clinical testing | The p.S1659F variant (also known as c.4976C>T), located in coding exon 10 of the BRCA2 gene, results from a C to T substitution at nucleotide position 4976. The serine at codon 1659 is replaced by phenylalanine, an amino acid with highly dissimilar 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. |
