Article Excerpts about Angelman syndrome

Angelman syndrome is a neurological disorder characterized by severe congenital mental retardation, unusual facial appearance, and muscular abnormalities. (Source: excerpt from NINDS Angelman Syndrome Information Page: NINDS)

Definitions of Angelman syndrome:

A condition in which children laugh frequently for almost any reason and whose jerky movements and flapping of the hands are similar to those of a marionette, or puppet-- hence the synonym "happy puppet syndrome." Other disorders include a peculiar facial expression, mental retardation, movement disorders, microbrachycephaly, and various neurological disorders. - (Source - Diseases Database)

Angelman syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Angelman syndrome, or a subtype of Angelman syndrome, affects less than 200,000 people in the US population.
Source - National Institutes of Health (NIH)

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Angelman syndrome as a "rare disease".
