Invitae RCV001032861 SCV001196168 pathogenic Hereditary breast ovarian cancer syndrome 2019-12-04 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 22-23 of the BRCA1 gene. The 5' boundary is likely confined to intron 21. 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. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. Deletions encompassing exons 22-23, which in the literature are known as deletions of exons 23-24, have been reported in several individuals and families affected with breast and/or ovarian cancer (PMID: 16715518, 16793929, 17333342, 18431737, 24825132). In one of these families the deletion was shown to segregate with the disease in four affected individuals (PMID: 16793929). For these reasons, this variant has been classified as Pathogenic.
