What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this registry could provide researchers with the data needed to design better clinical trials and develop treatments for Rett syndrome.
What could go wrong: This is an observational registry, not a treatment trial. It relies on caregiver reports, which may be incomplete or biased, and results may take years to impact care.
