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.

affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners,
currently defines a condition rare when it affects 1 person per 2,000.
