How Can Genetics Help Us Understand Autism?

Autism affects how people communicate, interact, and respond to things around them. People on the autism spectrum often have very strong interests, do some things repeatedly, and may feel most comfortable keeping their routines the same. Genetic tests can identify a cause for autism in up to one in three people. While these tests cannot diagnose autism, after a diagnosis is made, genetic testing can give doctors helpful clues to help families and find the right support. In this article, we explain key information about genetics, how genetic testing works, and how it can be used in autism. Taking a genetic test is a personal choice, and it is important to talk with doctors or other healthcare professionals before making that decision. However, by helping people understand these topics, we hope to make it easier for families to ask questions, make choices, and get the support that fits them best.
