The following genes were associated at P < 0.05 and also in the top 5th percentile within at least one of the GWAS discovery or replication datasets (Additional file 7: Table S6): SEPT1 (psychosis—in UK Biobank schizophrenia 20002_1289 P = 0.03), AIFM3 (mood disorders—in UK Biobank bipolar F31 P = 0.04), SCARF2 (mood disorders—in UK Biobank bipolar F31 P = 0.003), HIC2 (mood disorders—in UK Biobank bipolar 20002_1991, P = 0.004), ZNF48 (bariatric surgery—in UK Biobank BMI 3.7 × 10−6). This evidence concerns the gene HIC2 and psychotic disorder.
