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-AS1 (HGNC:56684): (DOCK6 antisense RNA 1)

This sequence change creates a premature translational stop signal (p.Gln1188*) 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 (rs372751467, gnomAD 0.006%). 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: 499360). For these reasons, this variant has been classified as Pathogenic. -

Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The DOCK6 c.3562C>T variant is predicted to result in premature protein termination (p.Gln1188*). To our knowledge, this variant has not been reported in a patient with a DOCK6 related disorder. This variant is reported in 0.0057% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-11328056-G-A). Nonsense variants in DOCK6 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
