The MR data was downloaded from Wang et al. In this study, the authors performed Mendelian randomization (MR) analyses using eQTL from BrainMeta (N = 2865) and GWAS from PGC3 to identified causal risk genes for schizophrenia, using genes as exposure and schizophrenia as outcome, identified a total of 123 causal risk genes for schizophrenia.
