About The Study

COUNT is a multiphase study that aims to advance the understanding of autism spectrum disorder (ASD) symptoms, comorbidities, and the biology of ASD. Researchers will explore these questions through “multi-omic” profiling and analyzing data about your environment, symptoms, and biology. “Multi-omics” means we’ll be looking at many types of molecules from your samples.

Phase 1 is the first part of COUNT and will help researchers understand important information about feasibility, participant experience, and initial research findings. This will help shape future phases of the study.

This study involves 90 days of participation and there is no cost to participate.
