Department of Pathology and Laboratory Medicine, Sinai Health System RCV001358557 SCV001554327 uncertain significance Lynch syndrome no assertion criteria provided clinical testing The PMS2 p.Lys561Arg variant was not identified in the literature nor was it identified in the dbSNP, ClinVar, GeneInsight-COGR, Cosmic, MutDB, Zhejiang University Database, Mismatch Repair Genes Variant Database, or Insight Hereditary Tumors Database, databases. The variant was also not identified in the following control databases: the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The p.Lys561 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 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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.
