First, we implicate the major histocompatibility complex. Second, we provide molecular genetic evidence for a substantial polygenic component to the risk of schizophrenia involving thousands of common alleles of very small effect.

Genetics of schizophrenia (Review)

Genome-wide association studies have successfully identified several genes associated with increased risk for both disorders. This has allowed researchers to model the aggregate effect of genes associated with disease status and create a polygenic risk score PGRS for each individual. The interest in imaging genetics using PGRS has grown in recent years, with several studies now published. Results indicate that the effect of genetic load for SCZ and BD on brain function affects task-related recruitment, with frontal areas having a more prominent role, independent of task. Additionally, the results suggest that the polygenic architecture of psychotic disorders is not regionally confined but impacts on the task-dependent recruitment of multiple brain regions. Future imaging genetics studies with large samples, especially population studies, would be uniquely informative in mapping the spatial distribution of the genetic risk to psychiatric disorders on brain processes during various cognitive tasks and may lead to the discovery of biological pathways that could be crucial in mediating the link between genetic factors and alterations in brain networks. Psychosis is a serious mental illness characterized by delusions, hallucinations and disorganized thinking or behavior.

Common polygenic variation contributes to risk of schizophrenia and bipolar disorder

This is an open access article distributed under the terms of Creative Commons Attribution License. Schizophrenia is a common yet devastating mental disorder characterized by a series of cognitive, behavioral and emotional dysfunctions, none of which are pathognomonic for the disease. It includes both positive symptoms, mainly represented by hallucinations and delusions and negative ones, such as blunted affect, avolition and social isolation, along with disturbed attention, executive function and working memory 1.

Psychosis has been hypothesised to be a continuously distributed quantitative phenotype and disorders such as schizophrenia and bipolar disorder represent its extreme manifestations. Evidence suggests that common genetic variants play an important role in liability to both schizophrenia and bipolar disorder. Here we tested the hypothesis that these common variants would also influence psychotic experiences measured dimensionally in adolescents in the general population. Our aim was to test whether schizophrenia and bipolar disorder polygenic risk scores PRS , as well as specific single nucleotide polymorphisms SNPs previously identified as risk variants for schizophrenia, were associated with adolescent dimension-specific psychotic experiences. Polygenic risk scores were calculated using estimates of the log of odds ratios from the Psychiatric Genomics Consortium GWAS stage-1 mega-analysis of schizophrenia and bipolar disorder. Future research with PRS derived from larger samples, as well as larger adolescent validation samples, would improve the predictive power to test these hypotheses further.
