- -
- -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
- -
- -
Hereditary cancer-predisposing syndrome Benign:4
This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

PMS2, Exon 14, c.2340C>T, p.Pro780Pro, Benign (ACMG 5)rnThe c.2340C>T variant was not identified in the literature. The variant was also identified in dbSNP (ID: rs142230276 )“With untested allele”, with a minor allele frequency of 0.0012 (1000 Genomes Project), HGMD, COSMIC, MutDB, “Mismatch Repair Genes Variant Database”, “MMR Gene Unclassified Variants Database”, “InSiGHT Colon Cancer Database”, “Zhejiang Colon Cancer Database”, and in the ClinVar database with 3 separate submitters as a benign/likely benign variant. The variant was classified as “unclassified” by a clinical laboratory within the Canadian Open Genetics Repository (http://opengenetics.ca/). The variant was identified by the Exome Variant Server project in 23 of 4392 African American alleles (frequency: 0.005), although this low number of observations and low frequency is not substantive enough to determine the prevalence of the variant in the general population and its relationship to disease. The p.Pro780Pro 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.rnrnrnrnrnrnrnIn 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 unknown significance. -
