BACKGROUND: Earlier studies have shown that patients with schizophrenia have abnormalities in DNA methylation. Monoamine oxidase A (MAOA) has been extensively studied due to its biological role in neurological function. However, the relationship between the DNA methylation of the MAOA gene and schizophrenia is unclear. This study aims to elucidate the relationship between the methylation of the MAOA gene promoter and schizophrenia. METHODS: There were 151 individuals with schizophrenia (104 males and 47 females), which were diagnosed according to DSM-V, the DNA of peripheral blood of all samples was extracted and chemically modified with bisulfite. The promoter region of MAOA gene was sequenced by Methylation Target Technical Method (MethylTargetTM), and 247 controls (204 males and 43 females) included in the study. MAOA gene promoter methylation was compared between the case and control groups. Meanwhile, we measured DNA methylation in two regions of MAOA (MAOA-2 and MAOA-3). RESULTS: In the male schizophrenia group (BM) and the male control group (DM), MAOA-2 and MAOA-3 methylation were positively associated with schizophrenia. In the female schizophrenia group (BF) and the female control group (DF), MAOA-2 methylation was associated with schizophrenia. CONCLUSIONS: Although the role of gene methylation in the development of schizophrenia is still unclear, our findings suggest that DNA methylation of MAOA may contribute to the onset of schizophrenia. 2020 Annals of Translational Medicine.
