Finally, XAV939, an inhibitor of the canonical Wnt/β‐catenin pathway (a stabilizer of Axin in the β‐catenin destruction complex), rescued morphological impairments in iPSC‐derived cerebral organoids with mutations of the disrupted in schizophrenia 1 (DISC1) gene 82, the first gene that was identified as a risk factor for SCZ, BP, and MD. Here, DISC1 is linked to Menkes disease.
