Study to Explore Early Development (SEED)
10/2006 - 09/2015

The Study to Explore Early Development (SEED) is a ground-breaking study. It may help identify genetic and environmental links to Autism Spectrum Disorders (ASDs) and developmental disabilities. In the fall of 2007, California researchers began the first phase of SEED, recruiting 450 children between the ages of 2 and 5 and their families to take part. Funding was approved for a second phase, and recruitment began in the Summer of 2012. The study is being conducted in Alameda and Santa Clara Counties.


SEED is the largest study of its kind to date. Across the country about 2,700 children and their parents have already taken part. This includes families from many different backgrounds and six different regions of the United States: California, Colorado, Georgia, Maryland, North Carolina, and Pennsylvania.


SEED is funded by the Centers for Disease Control and Prevention (CDC).


In California, SEED is being carried out by Kaiser Permanente Northern California and the California Department of Public Health. Families do not have to be Kaiser members to participate.
