New genes contributing to autism and schizophrenia discovered;
Ok, I've now seen enough of these that I can't see it being "news" again until much bigger picture stuff comes along.

Artistic tendencies linked to schizophrenia gene
Kéri examined a gene involved in brain development called neuregulin 1, which previous studies have linked to a slightly increased risk of schizophrenia. Moreover, a single DNA letter mutation that affects how much of the neuregulin 1 protein is made in the brain has been linked to psychosis, poor memory and sensitivity to criticism.

People with two copies of the neuregulin 1 mutation – about 12 per cent of the study participants – tended to score notably higher on these measures of creativity, compared with other volunteers with one or no copy of the mutation. Those with one copy were also judged to be more creative, on average, than volunteers without the mutation. All told, the mutation explained between 3 and 8 per cent of the differences in creativity, Kéri says.

Schizophrenia and Bipolar Disorder Share Genetic Roots
A trio of genome-wide studies – collectively the largest to date – has pinpointed a vast array of genetic variation that cumulatively may account for at least one third of the genetic risk for schizophrenia. One of the studies traced schizophrenia and bipolar disorder, in part, to the same chromosomal neighborhoods.

Gene clues to schizophrenia risk
The researchers say that individually many of the genetic variations they have identified play only a tiny role in raising the risk of passing schizophrenia down the generations.

However, Dr Shaun Purcell, from Harvard University, who co-led one of the three teams, said: "Cumulatively, they play a major role, accounting for at least one-third - and probably much more - of disease risk."

Study clears cannabis of schizophrenia rap
In terms of estimated rate ratios, persons who develop cannabis-induced psychosis are as predisposed to schizophrenia spectrum disorder and other psychiatric disorders as those who develop schizophrenia spectrum disorder without a history of cannabis-induced psychosis.
