Angelman syndrome is a genetic condition that affects the nervous system. It usually isn’t detected until developmental delays become noticeable, such as speech and balance, mental disability, and seizures.

Delays in maturing, called developmental delays, begin between about 6-12 months of age. The delays often are the first signs of Angelman syndrome. Seizures may begin between the ages of 2-3 years old.

People with Angelman syndrome tend to live close to a typical life span. But the condition can’t be cured. Treatment focuses on managing medical, sleep and developmental issues.
