Despite a considerable interindividual variance, results showed that psychosis-induction was accompanied by a significant upregulation of the genes Slc2a5, Pld4, Olig1, Fgfr1, Gpr17, Cxcl14, Phlda3, Gna12, Abca2, Sox1, RGD1566085 and a down-regulation of Dpm2, Ergic2, Rab2a, Vma21 when AMPH-VEH was compared to the SAL-VEH group (Fig. 7a, b). The gene discussed is RAB2A; the disease is psychotic disorder.
