DNA is what makes you, you! Well, at least partly. Most scientists agree that our DNA can impact our development, but that our environment also plays a role. Our DNA codes for genes, which provide instructions for how we look, think, and behave.

Everyone is born with a unique set of DNA (except for identical twins, who actually share the same DNA!). Our DNA, or genetic code, comes from our parents.

Our bodies are made up of cells, and each of our cells contain a copy of our DNA. Therefore, you can get small amounts of DNA from almost anywhere- even from a piece of your hair! But large amounts of DNA are needed for research studies. One of the best ways to do this is by obtaining a sample of someone's blood. For our study, highly-skilled nurses draw blood from the preferred arm of each family member.

Most scientists agree that some combination of genetic and environmental factors contribute to the development of Autism Spectrum Disorder, but direct causes are still unknown. By conducting large-scale genetic studies, we can better understand the role that DNA plays in Autism.

It is also critical that Autism research reflects the diversity in our population, so we can be sure our findings are applicable to everyone. Because individuals with Black African ancestry have been historically underrepresented in Autism research, the goal of this project is to make sure these individuals are included.
