Researchers identify new genetic link to schizophrenia

Researchers have found variations in a small number of genes that appear to dramatically increase the likelihood of developing schizophrenia in some people. The interplay of a wide array of other genes is implicated for most people with schizophrenia, a severe brain disorder characterized by hallucinations, delusions and inability to function.

Scientists pinpoint genes that dramatically increase risk of schizophrenia - The Boston Globe

The second study identifies hundreds of common genetic variants that individually contribute only a tiny degree to schizophrenia, but together point to faulty communications between brain cells as a major cause of the disorder.

Landmark study reveals clearest genetic signals yet for schizophrenia risk

In a landmark genetic study of more than 121,000 people, an international consortium called SCHEMA, led by researchers at the Broad Institute of MIT and Harvard, has identified extremely rare protein-disrupting mutations in 10 genes that strongly increase an individual's risk of developing schizophrenia - in one instance, by more than 20-fold.

Genetic analysis finds rare, damaging variants contribute to the risk of schizophrenia

(Medical Xpress)-Via genetic analysis, a large international team of researchers has found rare, damaging gene variants that they believe contribute to the risk of a person developing schizophrenia. In their paper published in the journal Nature Genetics, the researchers describe their study, which involved analyzing data from a wide variety of sources, comparing what they found and describing their findings.

Nature Neuroscience - Volume 19 Issue 4, April 2016

In this Perspective, Murray Sherman discusses connectivity in the thalamocortical system, including the evidence that cortical areas are connected in parallel by direct and transthalamic pathways. Because thalamus receives inputs that form collaterals with subcortical motor regions, the author suggests that it may relay efference copy information.

Rare single gene mutation increases risk of schizophrenia 35-fold, new study suggests

Genetic factors play a major role in schizophrenia but scientists are only now beginning to identify the specific genes involved. A new study published in Nature Neuroscience shows that rare mutations in the SETD1A gene dramatically increase the risk of developing schizophrenia.
