Genes for schizophrenia found.

There is now some solid evidence that there are genes that predispose a person to develop schizophrenia. Michael O'Donovan and colleagues, of Cardiff University, found a gene called ZNF804A which apparently increases the risk of the disorder by about 1%. In another study, David St Clair and colleagues, of the University of Aberdeen, found that when regions on chromosomes 1 and 15 are missing, the risk of schizophrenia can rise 15 times.

Finally, the International Schizophrenia Consortium have found that people who suffer from schizophrenia tend to have more copy number variations--repeated or missing gene fragments--than healthy individuals.
