Invitae RCV000629948 SCV000750904 likely pathogenic Hereditary nonpolyposis colon cancer 2018-10-10 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 8 of the PMS2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with PMS2-related disease. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PMS2 are known to be pathogenic (PMID: 21376568, 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.
