About this study

Official title: Study on the Brain Network of Angelman Syndrome Based on Multi-modal Brain Image and Neural-EEG Data

The aims of study on Angelman syndrome:

  1. Establish the Angelman syndrome database
  2. Explore the brain Network of Angelman Syndrome Based on Multi-modal Brain Image and Neural-EEG Data
Read the detailed description
  1. The participants recruitment: from Chinese Angelman Syndrome Patients group (Angelhome : angelman225@126.com) 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 groupRoleWhat they receive
Angelman syndromeCases 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)

Questions about this trial

What is this clinical trial studying?

An observational study of Angelman Syndrome, run by Fudan University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Angelman syndrome databas; Brain Network of Angelman syndrome (time frame: 0-18 years old). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03358823, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
