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 c.1362_1365delAACT (p.T455Sfs*24) alteration, located in exon 12 (coding exon 12) of the DOCK6 gene, consists of a deletion of 4 nucleotides from position 1362 to 1365, causing a translational frameshift with a predicted alternate stop codon after 24 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, this variant has an overall frequency of 0.005% (13/270528) total alleles studied. The highest observed frequency was 0.022% (5/23052) of African/African American alleles. This variant has been identified in conjunction with other DOCK6 variants in individuals with features consistent with Adams-Oliver syndrome (Shaheen, 2011). Based on the available evidence, this alteration is classified as pathogenic. -
