Angelman syndrome is a genetic disorder. It causes developmental disabilities, neurological problems and sometimes, seizures.
People with Angelman syndrome often smile and laugh frequently, and have happy, excitable personalities.
Developmental delays, between about 6 and 12 months of age, are usually the first signs of Angelman syndrome. Seizures often begin between the ages of 2 and 3 years old.
People with Angelman syndrome tend to live a normal life span, but the disease cannot be cured. Treatment focuses on managing medical and developmental issues.
