Hunt for CDH genes launches: 3,000 participants sought
NCT ID NCT00950118
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study aims to identify genes that make a person more likely to develop congenital diaphragmatic hernia (CDH), a birth defect where the diaphragm doesn't form properly. Researchers will collect DNA samples from 3,000 people with CDH or a family history of it, along with their families. By understanding the genetic causes, they hope to pave the way for future prevention or treatment.
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 genetic risk factors for congenital diaphragmatic hernia, pointing toward future prevention or treatment strategies.
- What could go wrong
- This is an observational genetic study, not a treatment trial. It may take years to translate findings into clinical applications, and the genetic causes may be complex and hard to pinpoint.
