Invitae RCV000707905 SCV000837015 pathogenic Hereditary breast ovarian cancer syndrome 2019-05-29 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 20-23 of the BRCA1 gene. The 5' boundary is likely confined to intron 19. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. Deletions encompassing exons 20-23, which in the literature are also known as deletions of exons 21-24, have been reported in individuals affected with breast and ovarian cancer (PMID: 16551709, 22544547, 20232141, 17688236). While this deletion is not anticipated to result in nonsense mediated decay, it is expected to result in the loss of amino acids Ile1760-Tyr1863 of the BRCA1 protein, including the translational stop codon, thereby truncating the C-terminal BRCT domain (PMID: 22843421). For these reasons, this variant has been classified as Pathogenic.
