Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. The participants recruitment: from Chinese Angelman Syndrome Patients group (Angelhome : [email protected]) and Children's Hospital of Fudan University.
2. Fistly all participants had clinically and molecularly confirmed as Angelman syndrome . All participants should entry the online questionnaries and carified by telephone or on site . All the information will be recorded in the Angelman syndrome database. Investigators will analyze and summarize the relationship of phenotype and genotype(n=200).
3. Participants who assigned the informed consent and will undergo the brain MRI inspection and Neural-EEG recording in the Children's Hospital of Fudan University. The healthy age- and sex-matched control participants will enrolled in the same hospital. The Investigators will explore the brain morphology and electrophysiological alterations and for Angelman syndrome (AS) children among the different genotypes（n=200）.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Angelman syndrome

Cases were children with the diagnosis meet the all 4 major criteria developmental delay, speech impairment, movement or balance disorder, and behavioral characteristics, as well as the presence of 3 of 6 minor criteria, including postnatal deceleration of head growth, seizures, abnormal EEG, sleep disturbance, attraction to or fascination with water, and drooling (summary by Tan et al., 2011). all patients meet the 4 known genetic mechanisms can cause Angelman syndrome (AS).,including maternal deletions involving chromosome 15q11.2-q13;paternal uniparental disomy of 15q11.2-q13;imprinting defectsand mutations in the gene encoding the ubiquitin-protein ligase E3A gene (UBE3A; 601623)
