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]

This sequence change creates a premature translational stop signal (p.Glu1494*) in the DOCK6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DOCK6 are known to be pathogenic (PMID: 21820096, 25824905). This variant is present in population databases (rs568049240, gnomAD 0.03%). This premature translational stop signal has been observed in individual(s) with Adams-Olive syndrome (PMID: 25091416, 28884918). ClinVar contains an entry for this variant (Variation ID: 522048). For these reasons, this variant has been classified as Pathogenic. -
