Genetics plays an important role in autism, and autism can occur in more than one family member. Its genetics are complex. Recognising similarities does not establish a diagnosis or predict another person’s needs.

A thoughtful family conversation

You can talk about your own experiences without diagnosing relatives. Respect each person’s choice about labels, assessment and disclosure.

Go at a pace that feels comfortable.

Understanding without blame

Autism is not caused by parenting. A genetic contribution is not anyone’s fault. Family similarities can be meaningful, but support should be based on each person’s experiences rather than comparisons.

This resource cannot estimate inheritance chances or interpret genetic tests. If you have personal questions about genetic testing or family planning, a healthcare professional or genetics service can discuss your circumstances.
