Genetic research has shown that there is no one gene that causes autism. These three studies show that several genetic mutations may increase the risk of getting autism and that different mutations may affect people in different ways. Although much more research is needed, identifying more genetic mutations could help researchers identify targets to focus on in order to find methods to counteract the developmental disabilities they can cause. Additionally, this research could lead to diagnostic tests that could identify children who are at risk for autism so that they can get behavioral intervention as early as possible.
