The genetic association of the two problems is unclear. We conducted a bidirectional Mendelian randomization (MR) analysis to explore the potential casual relationships between mood disorder subtypes (bipolar disorder, depression, manic/hyper symptoms) and PE.Methods: Summary statistics for bipolar disorder (7481 cases and 9250 controls), depression (13,559 cases and 435,855 controls), manic/hyper symptoms (3177 cases and 28,140 controls) were derived from IEU open GWAS project. Summary data for PE were obtained from FinnGen consortium (7965 cases and 211,852 controls) and IEU open GWAS project (2355 cases and 264,887 controls). Four methods were applied in our MR analysis, including the inverse variance weighting (IVW), MR-Egger, weighted median and weighted mode. Meta-analysis method was used to assess the combined effect from two independent database. A series of sensitivity analyses were conducted to estimate the robustness of results.Results: The combined effect from two data sources indicated that there were casual associations between bipolar disorder and PE (OR = 1.15, 95% CI: 1.08– 1.22, P < 0.001), depression and PE (OR = 1.07, 95% CI: 1.01– 1.13, P = 0.01). No significant association was observed between manic/hyper symptoms and PE. Reverse MR analysis demonstrated no casual effect of PE on bipolar disorder, depression or manic/hyper symptoms. Sensitivity analysis confirmed the robustness of the bidirectional MR results.Conclusion: Our findings provided evidence that bipolar disorder and depression are causally associated with PE.Keywords: mood disorder, preeclampsia-eclampsia, Mendelian randomization analysis
