NCT ID NCT01998750
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find rare genetic changes that lead to severe obesity starting before age 6. Researchers will enroll 500 children and adults who had a very high BMI (above the 99th percentile) at a young age. Participants will answer health questions, have a brief physical exam, and give a blood or saliva sample for genetic testing. Family members may also be invited to join.
