RCV001179294 | SCV001343911 | pathogenic | Hereditary cancer-predisposing syndrome | 2020-05-13 | criteria provided, single submitter | clinical testing | This variant deletes 1 nucleotide in exon 10 of the BRCA2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, 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). Loss of BRCA2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. |

RCV001192532 | SCV001360739 | likely pathogenic | Hereditary breast ovarian cancer syndrome | 2019-08-27 | criteria provided, single submitter | clinical testing | Variant summary: BRCA2 c.1233delA (p.Leu413TyrfsX17) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 250274 control chromosomes (gnomAD). To our knowledge, no occurrence of c.1233delA in individuals affected with Hereditary Breast and Ovarian Cancer and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
