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]
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.

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 06, 2022Algorithms 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. This variant has not been reported in the literature in individuals affected with DOCK6-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 663 of the DOCK6 protein (p.Gln663Arg). -
