Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_000179.3(MSH6):c.371G>A(p.Gly124Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,614,070 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. G124R) has been classified as Uncertain significance.

Hereditary nonpolyposis colorectal neoplasms Uncertain:1
This variant is not present in population databases (gnomAD no frequency). 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"). ClinVar contains an entry for this variant (Variation ID: 485858). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 124 of the MSH6 protein (p.Gly124Glu). 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
The p.G124E variant (also known as c.371G>A), located in coding exon 2 of the MSH6 gene, results from a G to A substitution at nucleotide position 371. The glycine at codon 124 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
