| Ambry Genetics | RCV000219913 | SCV000277776 | likely benign | Hereditary cancer-predisposing syndrome | 2020-02-25 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV000463676 | SCV000549721 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2024-10-15 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 2582 of the BRCA2 protein (p.Ala2582Thr). 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: 233407). Invitae Evidence Modeling incorporating data from in vitro experimental studies (PMID: 33609447) indicates that this missense variant is not expected to disrupt BRCA2 function with a negative predictive value of 95%. 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. |

RCV000219913 | SCV004362223 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-10-25 | criteria provided, single submitter | clinical testing | This missense variant replaces alanine with threonine at codon 2582 of the BRCA2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). However, a functional study has reported that this variant does not impact BRCA2 function in a homology-directed repair assay (PMID: 33609447). This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
