Genes affected
PMS2 (HGNC:9122): (PMS1 homolog 2, mismatch repair system component) The protein encoded by this gene is a key component of the mismatch repair system that functions to correct DNA mismatches and small insertions and deletions that can occur during DNA replication and homologous recombination. This protein forms heterodimers with the gene product of the mutL homolog 1 (MLH1) gene to form the MutL-alpha heterodimer. The MutL-alpha heterodimer possesses an endonucleolytic activity that is activated following recognition of mismatches and insertion/deletion loops by the MutS-alpha and MutS-beta heterodimers, and is necessary for removal of the mismatched DNA. There is a DQHA(X)2E(X)4E motif found at the C-terminus of the protein encoded by this gene that forms part of the active site of the nuclease. Mutations in this gene have been associated with hereditary nonpolyposis colorectal cancer (HNPCC; also known as Lynch syndrome) and Turcot syndrome. [provided by RefSeq, Apr 2016]

Likely benign, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The PMS2 p.Val159= variant was not identified in the literature nor was it identified in the following databases: COGR, Clinvitae, Cosmic, Insight Colon Cancer Gene Variant Database, Zhejiang Colon Cancer Database, Mismatch Repair Genes Variant Database, or the Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs147701251) “With Likely benign allele”, ClinVar (classified as benign by GeneDx and likely benign by Ambry Genetics, Invitae, Counsyl and Color Genomics Inc), and in control databases in 21 of 276590 chromosomes at a frequency of 0.00008 increasing the likelihood this could be a low frequency variant (Genome Aggregation Consortium Feb 27, 2017). The observations by population include Latino in 3 of 34398 chromosomes (freq: 0.00009), European Non-Finnish in 14 of 126292 chromosomes (freq: 0.0001), and South Asian in 4 of 30766 chromosomes (freq:0.0001); the variant was not observed in African, Ashkenazi Jewish, East Asian, and European Finnish populations. The p.Val159= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
