The MSH2 p.Thr934Lys variant was not identified in the literature, nor has it been previous identified by our laboratory. The variant was identified in UMD (1X as an unclassified variant). The p.Thr934 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; in addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. However, this information is not predictive enough to rule out pathogenicity. This substitution occurs in the last codon before the translational stop codon. 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 unknown significance.
