Variant summary: Variant affects a non-conserved nucleotide and results in a nonsense mutation predicted to cause a loss of normal protein function due to production of a truncated protein or by the absence of the protein product due to nonsense-mediated mRNA decay. It is absent from the large and broad cohorts of the ExAC project and to our knowledge, it was not reported in affected individuals either. Loss of function of PMS2 is a known mechanism of Lynch syndrome (GeneReviews), therefore, this nonsense variant was classified as Likely Pathogenic.
