Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 30, 2019 | 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with MSH6-related conditions. This variant is present in population databases (rs766557450, ExAC no frequency). This sequence change replaces lysine with threonine at codon 1233 of the MSH6 protein (p.Lys1233Thr). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and threonine. - |
