Ambry Genetics | RCV002445814 | SCV002611935 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-04-26 | criteria provided, single submitter | clinical testing | The p.K110E variant (also known as c.328A>G), located in coding exon 2 of the MSH2 gene, results from an A to G substitution at nucleotide position 328. The lysine at codon 110 is replaced by glutamic acid, an amino acid with similar properties. In a massively parallel cell-based functional assay testing susceptibility to a DNA damaging agent, 6-thioguanine (6-TG), this variant was reported to be functionally deleterious (Jia X et al. Am J Hum Genet, 2021 01;108:163-175). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
