Invitae RCV000546885 SCV000624587 likely pathogenic Hereditary nonpolyposis colorectal neoplasms 2017-02-21 criteria provided, single submitter clinical testing This variant is a gross duplication of the genomic region encompassing exons 7 to 15 of the MLH1 gene. While the exact position of the duplicated exons 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 variant has not been reported in the literature, loss-of-function variants in MLH1 are known to be pathogenic (PMID: 15713769, 24362816). 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.
