Schizophrenia -- a chronic mental illness that affects a person's thoughts, feelings and behavior -- is determined in part by genetic makeup. The DISC1 gene is associated with developing schizophrenia. DISC1 is involved in the growth of nerve cells, proper nerve signaling and the ability of the brain to grow and adjust (neuroplasticity) throughout a person's lifetime. Loss of DISC1 function can interrupt the normal signaling pattern, which may lead to schizophrenia-like symptoms, such as movement disorders, memory problems and reduced expression of emotions.
