The Rett Syndrome Global Registry

This is a global registry for people with Rett syndrome. It's a way for caregivers to share information about their loved one's condition and care. You can track symptoms and care strategies over time, and store important medical information in one place. This information helps researchers better understand Rett syndrome and develop new treatments. The registry aims to collect data on the types of genetic mutations (changes in genes) and diagnoses, as well as how developmental milestones are reached and the burden of symptoms over five years. Anyone with a diagnosis of Rett syndrome or a specific gene mutation (MECP2) can join, and a parent or caregiver must be able to provide consent.

Study design
This is an observational study, meaning researchers will collect information without giving any specific treatments. It aims to enroll 5000 participants.
What's involved
You would provide caregiver-reported information about your loved one with Rett syndrome. You can also choose to track symptoms and care strategies over time, and consolidate medical records.
Compensation
Not stated in the trial record.
Follow-up
Caregiver reports on developmental milestones and symptom burden will be measured over five years.

  • Frequency of genetic mutation types and clinical diagnoses.1 year

    Measured by data obtained from genetic reports and caregiver-reported clinical diagnoses of enrolled patients.

  • Caregiver report of developmental milestone achievement over time.5 years

    Measured by the percent of individuals who have achieved developmental milestones between 1 and 4 times per year.

  • Caregiver report of symptom burden and development history over time.5 years

    Measured by the percent of individuals who report symptoms and their intervention requirements between 1 and 4 times per year.

  • Caregiver report of composition and frequency of co-morbidities over time.5 years

    Measured by the type and number of non-Rett medical conditions between 1 and 4 times per year.

  • Caregiver report of the composition and frequency of medication and over-the-counter treatments over time.5 years

    Measured by the percent of individuals receiving these care strategies by symptom between 1 and 4 times per year.

  • Caregiver report of the composition and frequency of physician specialty utilization and care received at Rett Clinics over time.5 years

    Measured by the type and number of physician specialties used to manage symptoms and the number of individuals who receive care at a Rett clinic between 1 and 2 times per year.

  • Caregiver report of the composition of the barriers to clinical trial participation over time.5 years

    Measured by the type and number of reasons given for individuals not able or willing to participate in clinical trials between 1 and 2 times per year.
