An Overview Of Autism Spectrum Disorder (ASD)

What Are The Genetic Factors And Causes Of ASD?

The causes of ASD do not have enough supporting evidence to determine an exact cause, but two factors contribute to the cause of ASD: genetic and environmental. There is not one gene identified as a direct cause of autism. However, autism is known to run in families, which enforces the idea that it is a genetic disorder. Autism tends to transpire more often among patients diagnosed with medical conditions such as untreated phenylketonuria (PKU), tuberous sclerosis, fragile X syndrome, and congenital rubella syndrome.

Now that you know the genetic factors, continue reading to learn more about the environmental factors contributing to the development of autism.
