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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is looking for the genes that cause certain immune system problems. Researchers want to understand why some people get sick and others don't, even in the same family. Up to 5,000 people with immune disorders and their relatives will give blood or cheek cell samples for genetic testing. The goal is to learn more about these conditions and possibly help families understand their risks.

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 help doctors better understand, diagnose, and predict immune disorders, potentially guiding treatment and family planning.
What could go wrong
This is an observational study, not a treatment trial. It may not find clear genetic links for all families, and results may not directly change care.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

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

Who is studied

Probands and their blood relatives, of any age, sex, and ethnicity, who are affected, or suspected of being affected with genetic conditions and immune dysregulations under study are eligible to enroll as patients or family member enrollees. Fetal samples may be studied in selected cases where benefit, such as expedited postnatal treatment, could be realized.
