A gene list was generated based on genes previously found to be associated with schizophrenia from genetic and/or DNA methylation studies.11,12,19,37 This gene lists includes DRD2, NOS1, AKT1, HTR2A, SOX10, FOXP2, DTNBP1, NRG1, PPP3CC, BDNF, ZNF804A, NRGN, DRD4, MGST1, COMTD1 and GABRB2. Genes identified as differentially methylated after adjustment include NOS1, AKT1, DNMT1, SOX10, DTNBP1 and PPP3CC, whose distributions can be seen in Figure 3. The gene discussed is DRD4; the disease is schizophrenia.
