Additional GWS CpG sites associated with current PTSD include cg06595994 located in the DAZAP2 gene, which encodes for a protein involved in cell signaling, transcription regulation, and spermatogenesis, cg15559076 located in an intergenic region, and cg00770699 which maps to CREBZF involved in MAPK-Erk pathway, which is implicated in the long-term formation of fear-related memories [38]. This evidence concerns the gene CREBZF and post-traumatic stress disorder.
