Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_000179.3(MSH6):c.1993G>A(p.Glu665Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,878 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. E665D) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 15, 2020 | The p.E665K variant (also known as c.1993G>A), located in coding exon 4 of the MSH6 gene, results from a G to A substitution at nucleotide position 1993. The glutamic acid at codon 665 is replaced by lysine, an amino acid with similar properties. This amino acid position is 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. - |
