Description

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: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with MYH11-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with arginine at codon 1918 of the MYH11 protein (p.Thr1918Arg). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and arginine.
