Genes affected

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. [provided by Alliance of Genome Resources, Apr 2022]

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]
