Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000586604 SCV000697381 likely pathogenic Lynch syndrome 2016-11-21 criteria provided, single submitter clinical testing Variant summary: The PMS2 c.733_741delinsGCTGTGCTGTGAAG (p.Leu245Alafs) variant results in a premature termination codon, predicted to cause a truncated or absent PMS2 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.Arg341fs). One in silico tool predicts a damaging outcome for this variant. This variant is absent in 120358 control chromosomes. No homology was found in this region between PMS2 and its pseudogenes. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as likely pathogenic.
