Angelman Syndrome is a rare genetic disorder that affects the nervous system. People with this syndrome may have trouble with movement and speech, and often have a happy demeanor. This study aims to learn more about how Angelman Syndrome affects children and adults over time. Researchers will gather information from both doctors and parents to help understand the condition better and improve future care.

To join this study, participants must have a confirmed diagnosis of Angelman Syndrome. If someone has another condition that affects their brain development, they cannot join. The study will follow participants over a long period to see how the condition changes and to set standards for future research.

• Duration: This study is long-term, meaning it will take place over several years.
• Visits: Participants will need to come in for regular check-ups.
• Benefits: While there may be no direct benefits to participants, the information gathered will help improve future treatments and care for Angelman Syndrome.
