Genes affected

DOCK6 (HGNC:19189): (dedicator of cytokinesis 6) This gene encodes a member of the dedicator of cytokinesis (DOCK) family of atypical guanine nucleotide exchange factors. Guanine nucleotide exchange factors interact with small GTPases and are components of intracellular signaling networks. The encoded protein is a group C DOCK protein and plays a role in actin cytoskeletal reorganization by activating the Rho GTPases Cdc42 and Rac1. Mutations in this gene are associated with Adams-Oliver syndrome 2. [provided by RefSeq, Dec 2011]

DOCK6 links:

ANGPTL8 (HGNC:24933): (angiopoietin like 8) Predicted to enable hormone activity. Involved in regulation of lipid metabolic process and triglyceride homeostasis. Acts upstream of or within positive regulation of protein processing and regulation of lipoprotein metabolic process. Located in extracellular region.

This variant has not been reported in the literature in individuals affected with DOCK6-related conditions. 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 tolerated. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 645 of the DOCK6 protein (p.Arg645Gln). -
