Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000179.3(MSH6):c.2491C>T(p.Pro831Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,182 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P831A) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 03, 2020 | 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. This variant has not been reported in the literature in individuals with MSH6-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with serine at codon 831 of the MSH6 protein (p.Pro831Ser). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and serine. - |
