Scientists say they have identified a gene that may predispose some people to schizophrenia.
A particular variant of the gene showed up in people with the mental illness far more often than one would expect by chance, researchers reported Monday.That variant may predispose some people to schizophrenia, or it may lie very close to some other unknown gene that does so, they concluded.
But they cautioned that the finding could also have nothing to do with schizophrenia and could just be a result of how the study was done.
The work was presented at the annual meeting of the American Psychiatric Association by Alan Sanders and colleagues at the Baylor College of Medicine in Houston.
Schizophrenics show such symptoms as delusions, such as thinking they are somebody else or suspecting others are trying to harm them, and hallucinations and thought disorders, in which they may shift between topics without realizing they are making no sense.
