The PMS2 p.Met600Val variant was identified in 1 of 1144 proband chromosomes (frequency: 0.0009) from individuals or families with atherosclerosis (Johnston 2012,). The variant was identified in dbSNP (rs1304634005) as “NA” and ClinVar (classified as uncertain significance by Color and Counsyl). The variant was identified in control databases in 2 of 251,454 chromosomes at a frequency of 0.000008 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 1 of 10,078 chromosomes (freq: 0.0001) and East Asian in 1 of 18,394 chromosomes (freq: 0.00005), while it was not observed in the African, Latino, Finnish, European, Other or South Asian populations. The p.Met600 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
