Genes affected

DOCK7 (HGNC:19190): (dedicator of cytokinesis 7) The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) that plays a role in axon formation and neuronal polarization. The encoded protein displays GEF activity toward RAC1 and RAC3 Rho small GTPases but not toward CDC42. Several transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces arginine with serine at codon 1547 of the DOCK7 protein (p.Arg1547Ser). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and serine. This variant is present in population databases (rs115353638, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with DOCK7-related conditions. 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: "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. -
