Invitae RCV000231687 SCV000284920 pathogenic Familial cancer of breast 2015-12-10 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 7 to 11 of the BARD1 gene. The 5' boundary is likely confined to the intronic region between exons 6 and 7. 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 BARD1 protein. While this particular variant has not been reported in the literature, truncating variants in BARD1 are known to be pathogenic (PMID: 21344236, 22006311, 20077502). Deletion of exons 7-11 removes the C-terminal BRCT domains of the BARD1 protein. Experimental studies have shown that the BRCT domains are required for BARD1 homology-directed repair activity and the maintenance of chromosomal stability in vitro (PMID: 17848578). For these reasons, this variant has been classified as Pathogenic.
