Angelman Syndrome Natural History Study

This study is being done to better understand Angelman syndrome (AS). Participants will include both children and adults with a diagnosis of AS. The study will collect data regarding medical, behavioral, and developmental challenges in individuals with AS over time. Participants will be invited to return for yearly clinical evaluations yearly until the study runs out of funding. We hope clinicians will be able to help individuals with AS better if we understand the different pattern of symptoms that appear in individuals with AS over their lifetimes.
