Invitae RCV001362873 SCV001558921 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2023-07-12 criteria provided, single submitter clinical testing 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. 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. ClinVar contains an entry for this variant (Variation ID: 1054381). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 1068 of the MSH6 protein (p.Arg1068Gly).
Ambry Genetics RCV003355435 SCV004055245 uncertain significance Hereditary cancer-predisposing syndrome 2023-06-15 criteria provided, single submitter clinical testing The p.R1068G variant (also known as c.3202C>G), located in coding exon 5 of the MSH6 gene, results from a C to G substitution at nucleotide position 3202. The arginine at codon 1068 is replaced by glycine, an amino acid with dissimilar properties. This amino acid position is conserved. 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.
