Canadian Angelman Syndrome Society

The Canadian Angelman Syndrome Society (CASS) was incorporated in 1993 as a nonprofit charity and established to educate concerned families, the medical and educational communities, and the general public on the diagnosis, treatment, and prevention of Angelman syndrome. Angelman syndrome is a rare genetic disorder characterized by mental and motor retardation, absence of speech, muscular abnormalities, unprovoked laughter, and characteristic facial abnormalities. CASS consists of approximately 150 members who are dedicated to educating parents and professionals about Angelman syndrome and disseminating information on this disorder. CASS provides a regular newsletter, offers networking services for affected parents, and conducts a yearly conference.
