| Ambry Genetics | RCV000565423 | SCV000660856 | likely benign | Hereditary cancer-predisposing syndrome | 2019-02-20 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: 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. |

RCV000565423 | SCV001355934 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-05 | criteria provided, single submitter | clinical testing | This missense variant replaces valine with isoleucine at codon 608 of the BARD1 protein. Computational prediction tools and conservation analyses suggest that this variant may not impact the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 1/251050 chromosomes in the general population by the Genome Aggregation Database (gnomAD). 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. |
| Invitae | RCV002526768 | SCV003353833 | uncertain significance | Familial cancer of breast | 2022-05-04 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The isoleucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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 has not been reported in the literature in individuals affected with BARD1-related conditions. This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 608 of the BARD1 protein (p.Val608Ile). This variant is present in population databases (rs778987552, gnomAD 0.0009%). ClinVar contains an entry for this variant (Variation ID: 479140). |
