Understanding Autism: Exploring Genetic, Environmental, and Biological Factors in Siblings

What's the study about?

The GEMMA (Genome, Environment, Microbiome, and Metabolome in Autism) project aims to understand the many factors that contribute to the development of autism in children who have an autistic sibling.

Who can participate?

  • 0-6 months old
  • Has an autistic full sibling

What will participants be doing?

  1. Online surveys about food, health, and behavior every month
  2. Behavioral assessments (on Zoom) every 6 months from ages 1 to 3
  3. Periodic saliva, urine, stool, and blood samples (done at home/locally) until age 3
  4. One time samples from at least 1 biological parent and the sibling with ASD

All infant participants will receive early developmental assessments from study psychologists.

Why is this important?

Your family will be contributing to research that aims to help improve the early diagnosis of autism, as well as understand the GI symptoms associated with autism.
