NCT ID NCT00024804
First seen Jun 27, 2026 · Last updated Sep 17, 2026 · Updated 14 times
Summary
This study aims to collect information and bone samples from up to 1,000 people with bone or mineral disorders, such as tumor-induced osteomalacia or familial tumoral calcinosis. Participants receive standard medical evaluations and may provide bone tissue from surgery or a biopsy. No experimental treatments are given; the goal is to better understand these conditions and inspire future research.
