Variant summary: PMS2 c.1688_1689delinsAG (p.Arg563Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00023 in 276964 control chromosomes. The observed variant frequency is approximately 3 fold of the estimated maximal expected allele frequency for a pathogenic variant in PMS2 causing Hereditary Nonpolyposis Colorectal Cancer phenotype (7.1e-05), strongly suggesting that the variant is benign. c.1688_1689delinsAG has been reported in the literature in one individual affected with Breast Cancer (Chan_2018). This report does not provide unequivocal conclusions about association of the variant with Hereditary Nonpolyposis Colorectal Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (likely benign n=2, VUS n=2). Based on the evidence outlined above, the variant was classified as likely benign.
