Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000781757 SCV000920054 likely pathogenic Lynch syndrome 2018-09-13 criteria provided, single submitter clinical testing Variant summary: PMS2 c.1351delA (p.Arg451GlyfsX18) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. p.Ile611fsX2, p.Leu625X and p.Gln643X). The variant was absent in 246264 control chromosomes. To our knowledge, no occurrence of c.1351delA in individuals affected with Lynch Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
