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]

The p.Arg1526X variant in DOCK6 has not been reported in individuals with Adams- Oliver syndrome. It is a nonsense variant that leads to a premature termination codon at position 1526, which is predicted to lead to a truncated or absent prot ein. This variant has been identified in 3/98220 of chromosomes by the Exome Agg regation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs374530179) th ough its frequency is low enough to be consistent with a recessive carrier frequ ency. In summary, although additional studies are required to fully establish it s clinical significance, the p.Arg1526X variant is likely pathogenic for Adams-O liver syndrome in a recessive manner based upon predicted loss of function of th e protein. -

This sequence change creates a premature translational stop signal (p.Arg1526*) 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 (rs374530179, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DOCK6-related conditions. ClinVar contains an entry for this variant (Variation ID: 504926). For these reasons, this variant has been classified as Pathogenic. -
