This project was funded by the Canadian Angelman Syndrome Society (CASS) and the Angelman Syndrome Foundation (ASF), and developed by the ASF.  CASS and ASF welcome any feedback from users regarding your experience in using the series. Contact the ASF at 800-432-6435, or contact CASS at 403-931-2415.

The series is not intended to replace efforts already in progress with doctors and/or therapists; rather, the series provides supplementary information to these efforts to further assist with understanding the complex factors that result in these behaviors.
