Variant summary: PMS2 c.1501G>A (p.Val501Met) results in a conservative amino acid change in the encoded protein sequence. Three of three in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.4e-05 in 364708 control chromosomes, predominantly at a frequency of 7.8e-05 within the Non-Finnish European subpopulation in the gnomAD database (v2.1 exomes- and v3.1 genomes dataset). The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is slightly higher than the estimated maximum allele frequency for a pathogenic variant in PMS2 causing Hereditary Nonpolyposis Colorectal Cancer phenotype (7.1e-05), suggesting that the variant could be a benign polymorphism. However, the variant is located in a region that is highly homologous to a PMS2 pseudogene and the technology utilized for these datasets does not rule out pseudogene interference, therefore these data might not be reliable. The variant, c.1501G>A, has been reported in the literature as a germline variant in an individual affected with a tumor that belongs to the Lynch syndrome tumor spectrum (Li_2020), and in another individual affected with breast cancer, but was also found in several healthy controls (Dorling_2021, through LOVD). In addition, the variant was reported as somatic variant in a Lynch syndrome-associated tumor (Vargas-Parra_2017). These reports do 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. Six other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as VUS (n=5) or likely benign (n=1). Based on the evidence outlined above, the variant was classified as uncertain significance.
