RCV001902100 | SCV002129648 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2021-01-07 | 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. This variant has not been reported in the literature in individuals with BRCA2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with alanine at codon 2969 of the BRCA2 protein (p.Val2969Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine. |
| Ambry Genetics | RCV003299064 | SCV004005415 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-04-03 | criteria provided, single submitter | clinical testing | The p.V2969A variant (also known as c.8906T>C), located in coding exon 21 of the BRCA2 gene, results from a T to C substitution at nucleotide position 8906. The valine at codon 2969 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
