200-Patient study aims to unlock secrets of rare bone disease
NCT ID NCT07569731
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks back at the medical records of over 200 people with fibrous dysplasia, a rare bone condition that causes abnormal growths. Researchers want to learn more about the disease's features, treatments, and genetic causes. No new treatments are being tested; the goal is simply to gather information to better understand the condition.
