Study summary

The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.

Read the detailed description

Patients would be evaluated by a multidisciplinary team at specific time points every 3 months the first year, every 6 months the second year and once a year thereafter.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 9, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
