A Natural History Study of Angelman Syndrome
The goal of this observational study is to learn about the natural progression of Angelman syndrome (AS) in children and adults with a confirmed genetic diagnosis of AS. The main questions it aims to answer are:
* How do developmental skills, such as communication, motor abilities, and adaptive behaviors, change over a 1-year period in people with AS?
* Are there specific patterns in brain activity or sleep that are associated with changes in AS symptoms over time?
Participants will:
* Visit the study site 5 times over 1 year (approximately every 3 months) for assessments.
* Complete tests and questionnaires about development, behaviors, and sleep with the help of their caregivers.
* Undergo electroencephalograms (EEGs) to measure brain activity and wear a sleep-monitoring device at home (to collect actigraphy data).
