NCT ID NCT01401998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is creating a central database and tissue bank for rare diseases affecting the kidneys and liver, such as ARPKD and Joubert syndrome. Researchers will collect medical information, genetic samples, and tissues from 200 participants to help doctors and scientists better understand, diagnose, and treat these conditions. The goal is to share this information with families and healthcare providers to speed up research and improve care.
