NCT ID NCT00950118

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.
