New strategy could uncover genes at the root of psychiatric illnesses
Understanding the basis of psychiatric disorders has been extremely challenging because there are many genetic variants that may increase risk but are insufficient to cause disease. Now investigators describe a strategy that may help reveal how such 'subthreshold' genetic risks interact with other risk factors or environmental exposures to affect the development of the nervous system. Their research pinpoints a genetic variant that may predispose individuals to schizophrenia.
