There was a cluster of genes that was also shared only between ASD, PTSD, and SCZ, e.g., AC005829.1, KANSL1-AS1, LRRC37A2, MAPK8IP1P1, and MAPK8IP1P2. BIP and SCZ also shared a number of signals (AC006252.1, GLYCTK, GNL3, GOLGA2P7, NMB, and NEK4). This evidence concerns the gene NEK4 and post-traumatic stress disorder.
