Labcorp Genetics (formerly Invitae), Labcorp RCV001932403 SCV002135141 uncertain significance DOCK2 deficiency 2021-08-25 criteria provided, single submitter clinical testing This sequence change replaces serine with arginine at codon 1659 of the DOCK2 protein (p.Ser1659Arg). The serine residue is weakly conserved and there is a moderate physicochemical difference between serine and arginine. This variant is present in population databases (rs779372773, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with DOCK2-related conditions. 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 tolerated. 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.
