Invitae | RCV000460289 | SCV000549261 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2023-07-09 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 870 of the BRCA1 protein (p.Ala870Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 409297). 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 BRCA1 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. |

RCV003444237 | SCV004171515 | uncertain significance | Breast-ovarian cancer, familial, susceptibility to, 1 | 2023-10-25 | criteria provided, single submitter | clinical testing | The BRCA1 c.2609C>T (p.Ala870Val) missense change is absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a deleterious effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant is absent in the FLOSSIES database which contains genetic variants from women older than 70 years of age who have never had cancer (https://whi.color.com/). To our knowledge, this variant has not been reported 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.? |
