This sequence change replaces arginine with threonine at codon 635 of the KIAA2022 protein (p.Arg635Thr). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and threonine. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been reported in the literature in an individuals with the abnormality of nervous system (PMID: 26633542). This variant is present in population databases (rs766086192, ExAC 0.002%). -
