Natural History Study Overview

Participation in this study will help better our understanding of how development, behavior and communication change in individuals with AS over the course of their lives.

We may know a lot about AS, but there are certain ages and issues that have never been studied. The AS Natural History Study will find out what life with AS is really like throughout the lifetime.  

This study is being conducted at Boston Children’s Hospital and the ASF AS Clinic at Rady Children’s Hospital in San Diego. 


Participant Requirements

  • Individuals with Angelman Syndrome of any age are welcome. 
  • Participants will visit a study location once a year.  At each visit, participants will have a physical exam as well as answer questions and complete surveys.
