Study summary

Dr. Elliott Sherr and his collaborators at University of California, San Francisco (UCSF) are studying the genetic causes of disorders of cognition and epilepsy, in particular disorders of brain development that affect the corpus callosum, such as Aicardi syndrome, as well as two additional brain malformations, polymicrogyria and Dandy-Walker malformation. The goal of the investigators' research is to use a better understanding of the underlying genetic causes as a foundation to develop better treatments for these groups of patients.

Read the detailed description

We are studying both the genetics and clinical features of these disorders. We hope to understand the problems faced by individuals with these disorders as well as their causes. In the future, we hope to develop therapies that are geared specifically for individuals based on the underlying biology. To participate in the study, you will be asked to provide a copy of the magnetic resonance imaging (MRI) documenting Agenesis Corpus Callosum (ACC), Polymicrogyria (PMG), or Dandy-Walker malformation (DWM), clinical information, and saliva or blood samples from the affected individual and from the parents. Please see contact information and our webpage below.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2003 (actual). Primary completion is estimated for Jan 2027, 281 months after the start.

Of 78 non-industry observational studies under Brain Diseases, half reached primary completion within 62 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 193. This study's planned 281 months is above that.

Counting every sponsor, half of 87 studies reached it within 62 months; a quarter within 22 and three quarters within 193.

How these figures are worked out, and which studies are left out of them.

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 Aug 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
