Description

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 DOCK2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with valine at codon 72 of the DOCK2 protein (p.Glu72Val). The glutamic acid residue is weakly conserved and there is a moderate physicochemical difference between glutamic acid and valine. 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.
