Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1PM2BP4
The NM_000179.3(MSH6):c.3988C>A(p.Leu1330Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts 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. L1330R) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 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. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 leucine with isoleucine at codon 1330 of the MSH6 protein (p.Leu1330Ile). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and isoleucine. - |
