Quizplus · Accepted Answer

Schizophrenia is a complex psychiatric disorder that is believed to be caused by a combination of genetic, environmental, and developmental factors. Research has identified multiple genes that may be involved in the development of schizophrenia, but no single gene has been found to account for all cases. It is likely that schizophrenia is a polygenic disorder, which means that it involves multiple genes that interact with each other and with environmental factors to increase the risk of developing the disorder.
