Invitae RCV000550590 SCV000625179 likely pathogenic Hereditary nonpolyposis colon cancer 2017-05-04 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 7 of the MLH1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant has been reported in the literature in individuals affected with suspected Lynch syndrome (PMID: 21681552). ClinVar contains an entry for this variant (Variation ID: 90282). In summary, donor and acceptor splice site variants are typically loss-of-function (PMID: 16199547), and loss-of-function variants in MLH1 are known to be pathogenic (PMID: 15713769, 24362816). However, without additional functional and/or genetic data, this variant has been classified as Likely Pathogenic.
