New registry aims to unlock secrets of bone disorder
NCT ID NCT02597881
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is creating a database of health information from people with achondroplasia, a common form of dwarfism. Researchers will collect growth measurements and surgery records from up to 1,500 patients across several U.S. hospitals. The goal is to answer future questions about health outcomes and treatments, not to test a new therapy.
