Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 6P and 1B. PM1PM2PP3_ModerateBP6
The ENST00000234420.11(MSH6):c.3467T>A(p.Met1156Lys) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,816 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M1156T) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 13, 2022 | The p.M1156K variant (also known as c.3467T>A), located in coding exon 6 of the MSH6 gene, results from a T to A substitution at nucleotide position 3467. The methionine at codon 1156 is replaced by lysine, an amino acid with similar properties. This amino acid position is not well 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. - |
