Gene increases schizophrenia risk, study says

Scientists have discovered the first “risk gene” for schizophrenia found in the general population. An uncommon variation of a gene called Nogo, when inherited from both parents, increases the risk of developing schizophrenia, says a study to be published in Molecular Brain Research. Previous findings about other risk genes for the disease were restricted to specific ethnic groups. “Finding a risk gene in the general population – the first finding of this type internationally – opens the door to discovering new and related risk genes,” says one of the study’s authors. “Now scientists will know where to look for related genes…. This will help in diagnosis and potentially in the design of new medications for treatment of this terrible disease.”
