Invitae RCV001037661 SCV001201085 likely pathogenic Hereditary nonpolyposis colorectal neoplasms 2019-11-24 criteria provided, single submitter clinical testing This variant results in the deletion of part of exon 10 (c.857_885-857del) of the MLH1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with MLH1-related conditions. Loss-of-function variants in MLH1 are known to be pathogenic (PMID: 15713769, 24362816). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
