What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study

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.

Expected to finish

Oct 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
