Scientists hunt for genes behind kidney disease
NCT ID NCT02194582
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find the genetic causes of kidney diseases like FSGS and nephrotic syndrome. Researchers will collect saliva and urine samples from up to 2,050 participants, including patients and their family members, as well as healthy volunteers. The goal is to understand why these conditions run in families and what genes may be involved.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could identify genes that cause certain kidney diseases, pointing toward future treatments or early detection methods.
- What could go wrong
- This is an observational study for research only, not testing a treatment. It may not directly lead to new therapies, and results may take years to apply.
