The valine residue is highly conserved and there is a small physicochemical difference between valine and methionine. This variant is present in population databases (rs781198538, ExAC 0.02%). This variant has not been reported in the literature in individuals with B3GALNT2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
