Invitae | RCV000469066 | SCV000564062 | likely pathogenic | Familial cancer of breast | 2016-05-30 | criteria provided, single submitter | clinical testing | This variant is a gross duplication of the genomic region encompassing exon 8 of the CHEK2 gene. While the exact position of the duplicated exon cannot be determined from this data, the duplicated copy of this region is likely in tandem and may result in an absent or disrupted protein product. While this particular exon-level duplication has not been reported in the literature, truncating variants in CHEK2 are known to be pathogenic (PMID: 21876083, 24713400). In summary, sub-genic duplications are generally in tandem (PMID: 25640679), and result in an absent or disrupted protein. However, the exact location of this duplication has not been confirmed. Therefore, it has been classified as Likely Pathogenic. |
