The result of CNVplex assay (see Table 1) indicated that the deletion of PLA2G3[odds ratio(OR) = 6.905, 95% confidence interval (95% CI) = 1.496–31.873; p = 0.013], PLA2G4A (OR = 8.357, 95% CI = 1.018–68.604; p = 0.048), PLA2G4F (OR = 6.261, 95% CI = 1.339–29.277; p = 0.020) and PLA2G12A (OR = 5.175, 95% CI = 1.094–24.481; p = 0.038), as well as the duplication of PLA2G6 (OR = 11.580, 95% CI = 3.352–40.006; p < 0.001) was significantly associated with increased risk of schizophrenia. This evidence concerns the gene PLA2G4A and schizophrenia.
