Ambry Genetics RCV000563428 SCV000669981 uncertain significance Hereditary cancer-predisposing syndrome 2022-10-21 criteria provided, single submitter clinical testing The p.T914K variant (also known as c.2741C>A), located in coding exon 4 of the MSH6 gene, results from a C to A substitution at nucleotide position 2741. The threonine at codon 914 is replaced by lysine, an amino acid with similar properties. This amino acid position is well 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.
Invitae RCV001349194 SCV001543525 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2024-01-11 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with lysine, which is basic and polar, at codon 914 of the MSH6 protein (p.Thr914Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. ClinVar contains an entry for this variant (Variation ID: 483801). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MSH6 protein function with a negative predictive value of 95%. 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.
