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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with CFH-related conditions. This variant is present in population databases (rs749232210, ExAC 0.01%). This sequence change replaces threonine with methionine at codon 645 of the CFH protein (p.Thr645Met). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and methionine.
