Interestingly, five of these genes were found in more than one bivariate meta-analysis; specifically, (1) TRAF3IP2 and (2) MED19 in the schizophrenia + AD, schizophrenia + CUD, and schizophrenia + ND meta-analyses; along with (3) a BDNF, (4) FUT2 and (5) IZUMO1 for both the schizophrenia + AD and schizophrenia + CUD meta-analysis (Table 1). This evidence concerns the gene TRAF3IP2 and schizophrenia.
