Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000179.3(MSH6):āc.2605T>Cā(p.Cys869Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,834 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C869G) has been classified as Uncertain significance.

Hereditary nonpolyposis colorectal neoplasms Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 18, 2019 | This variant has not been reported in the literature in individuals with MSH6-related conditions. This variant is present in population databases (rs768941857, ExAC 0.006%). This sequence change replaces cysteine with arginine at codon 869 of the MSH6 protein (p.Cys869Arg). The cysteine residue is weakly conserved and there is a large physicochemical difference between cysteine and arginine. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 21, 2021 | The p.C869R variant (also known as c.2605T>C), located in coding exon 4 of the MSH6 gene, results from a T to C substitution at nucleotide position 2605. The cysteine at codon 869 is replaced by arginine, an amino acid with highly dissimilar properties. This amino acid position is not 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. - |
