One of the schizoaffective disorder-related genes, disrupted in schizophrenia 1 (DISC1), and its regulator DIX domain containing 1 (DIXDC1) have been shown to positively regulate Wnt/β‐catenin signaling in human NPC and FoxG1+/Tbr2+-positive neurons. Here, DIXDC1 is linked to schizoaffective disorder.
