What is the most common genetic cause of autism?

Known single-gene and chromosomal disorders associated with autism include Angelman syndrome, chromosome 15 duplication syndrome, tuberous sclerosis, and—the most common known single-gene cause of autism—Fragile X syndrome (FXS).

Does autism run in families?

ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.

How do kids get autism?

Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism.

Why would a doctor order genetic testing?

Clinical genetic tests are ordered by your doctor for a specific medical reason. DTC tests are usually purchased by healthy individuals who are interested in learning more about traits like ancestry, responses to medications, or risk for developing certain complex conditions.
