GeneDx RCV000486271 SCV000565243 uncertain significance not provided 2015-08-25 criteria provided, single submitter clinical testing This variant is denoted MSH6 c.4081T>C at the cDNA level and p.Ter1361GlnextX29 (X1361QextX29) at the protein level. This substitution is located in the stop codon of the MSH6 gene and results in the natural stop codon being changed to a Glutamine (TAG>CAG), resulting in the extension of the protein by 29 amino acids. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. Of note, this variant is in the C-terminal region of MSH6 which is a binding site for MSH2 (Kariola 2002). Based on currently available information, it is unclear whether MSH6 Ter1361GlnextX29 is pathogenic or benign. We consider it to be a variant of uncertain significance.

Invitae RCV000694136 SCV000822567 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2019-12-26 criteria provided, single submitter clinical testing This sequence change disrupts the translational stop signal of the MSH6 mRNA. It is expected to extend the length of the MSH6 protein by 29 additional amino acid residues. This variant is present in population databases (rs765098678, ExAC 0.006%). This variant has not been reported in the literature in individuals with MSH6-related conditions. ClinVar contains an entry for this variant (Variation ID: 418334). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
