Angelman Syndrome

What is Angelman syndrome?
Angelman syndrome (AS) is an inherited neurological disorder resulting in severe learning difficulties, developmental delay, and typical facial appearance and behavior. The most common age of diagnosis with Angelman syndrome is between three and seven years when the signs become most evident. AS affects about 1 in 12,000 to 20,000 people.

To learn more about genetics and to better understand how genes cause syndromes, see Your Child:  Genetic Syndromes.
