Fig. 1. Analysis workflow to investigate shared gene-based common variant associations between schizophrenia and other psychiatric phenotypes.

Fig. 1

a Gene-based aggregation of variant-wise common variant associations was performed using the MAGMA approach for schizophrenia (SZ), along with seven additional psychiatric disorders: bipolar disorder (BIP), attention-deficit/hyperactivity disorder (ADHD), eating disorder (ED), Tourette’s syndrome (TS), obsessive compulsive disorder (OCD), autism-spectrum disorder (ASD) and major depressive disorder (MDD). Genes were firstly selected which survived Bonferroni correction in the schizophrenia dataset along with at least one of the other disorders. Secondly, we identified a subset of genes associated with schizophrenia which did not display uncorrected nominal significance (P > 0.05) with any of the other seven phenotypes. Transcriptomic imputation (TWAS) was leveraged to investigate the correlation between imputed models of genetically regulated expression to explore the functional significance of variation affecting the (i) shared genes and (ii) genes only associated with schizophrenia. b A pairwise gene-based meta-analysis was performed between SZ and each disorder separately to identify significant genes which were not uncovered by analysing the respective phenotypes individually.
