Rare disease study aims to uncover secrets of harmful calcium buildup
NCT ID NCT07285421
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at people with Enamel Renal Syndrome, a rare genetic condition that causes calcium deposits in the body, leading to kidney and blood vessel problems. Researchers will measure kidney function and test how the body handles calcium, phosphate, water, and acid. The goal is to better understand what causes these calcium deposits. The study involves 30 patients and some healthy volunteers for comparison.
