TL;DR: In a genome-wide search for CNVs associating with schizophrenia, a population-based sample was used to identify de novo CNVs by analysing 9,878 transmissions from parents to offspring and three deletions significantly associate with schizophrenia and related psychoses in the combined sample.

TL;DR: The authors examined the role of common genetic variation in schizophrenia in a genome-wide association study of substantial size: a stage 1 discovery sample of 21,856 individuals of European ancestry and a stage 2 replication sample of 29,839 independent subjects.

TL;DR: Findings implicating the MHC region are consistent with an immune component to schizophrenia risk, whereas the association with NRGN and TCF4 points to perturbation of pathways involved in brain development, memory and cognition.

TL;DR: Differences in frequency of daily cannabis use and in use of high-potency cannabis contributed to the striking variation in the incidence of psychotic disorder across the 11 studied sites, giving important implications for public health.

TL;DR: It is concluded that NRXN1 deletions affecting exons confer risk of schizophrenia.
