    • Bipolar disorder is a highly heritable psychiatric disorder. We performed a genome-wide association study (GWAS) including 20,352 cases and 31,358 controls of European descent, with follow-up analysis of 822 variants with P < 1 × 10-4 in an additional 9,412 cases and 137,760 controls. Eight of the 19 variants that were genome-wide significant (P < 5 × 10-8) in the discovery GWAS were not genome-wide significant in the combined analysis, consistent with small effect sizes and limited power but also with genetic heterogeneity. In the combined analysis, 30 loci were genome-wide significant, including 20 newly identified loci. The significant loci contain genes encoding ion channels, neurotransmitter transporters and synaptic components. Pathway analysis revealed nine significantly enriched gene sets, including regulation of insulin secretion and endocannabinoid signaling. Bipolar I disorder is strongly genetically correlated with schizophrenia, driven by psychosis, whereas bipolar II disorder is more strongly correlated with major depressive disorder. These findings address key clinical questions and provide potential biological mechanisms for bipolar disorder.

  • Migration as a risk factor for schizophrenia: a Danish population-based cohort study.

    • Background A growing body of evidence suggests that migration is a risk factor for the development of schizophrenia, although the putative mechanism remains obscure. Aims To examine immigrant background and history of foreign residence as risk factors for schizophrenia. Method Using data from the Danish Civil Registration System, we established a population-based cohort of 2.14 million persons resident in Denmark by their fifteenth birthday. Schizophrenia in cohort members and parental psychiatric disorder were identified by cross-linkage with the Danish Psychiatric Case Register. Results The relative risk of developing schizophrenia was 2.45 (95% Cl 2.25-2.67) and 1.92 (95% Cl 1.74-2.12) among first- and second-generation immigrants respectively, and 1.60 (95% Cl 1.25-2.05) among Danes with a history of foreign residence. Conclusions Migration confers an increased risk for schizophrenia that is not solely attributable to selection factors and may also be independent of foreign birth.
