Study of Alkaptonuria

This study aims to better understand alkaptonuria, a rare genetic disease where a pigment called homogentisic acid builds up in the body, causing problems like arthritis, bone fractures, and heart issues. Researchers will collect medical information using modern techniques like cardiac CT, MRI, and echocardiograms. This information will help prepare for future drug trials. You may be able to join if you have alkaptonuria and are at least two years old. The study is ongoing and plans to enroll up to 300 participants. There are no specific interventions or drugs being tested in this observational study.
