Studying Immune System Disorders and Family Genetics
Part of Blood & lymphatic, Immune system & allergy clinical trials.
This research study examines how the immune system malfunctions in patients with common variable immunodeficiency (CVID)—a condition where the body doesn't make enough antibodies to fight infections. Researchers want to understand the genetics and immune patterns to help develop better treatments. Family members may also be asked to participate to help identify genetic causes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a confirmed diagnosis of CVID or a related immune disorder (such as selective IgA deficiency, agammaglobulinemia, or certain genetic immune conditions)
- You are at least 2 years old
- You have a history of repeated infections that suggest an immune problem
- Your primary doctor or specialist has referred you to this study
- You are willing to have your blood or tissue samples stored for future research
- You are not currently pregnant at the time you enroll (though you can stay in the study if you become pregnant while participating)

This study looks at how the immune system works in people who have abnormal immune function, often shown by unusual or repeated infections or long-lasting inflammation. It may involve tests using blood samples and storage of blood for future research.
This study aims to better understand primary immune disorders by collecting genetic and blood (and related) information. It may help researchers identify what causes these conditions and improve future testing and care.
This research study investigates problems with immune system cells called phagocytes that help fight infections. Researchers will study patients with suspected immune defects and their blood relatives to better understand these conditions and develop better care.
This study looks for genetic causes of immune problems, such as unusually frequent infections, abnormal allergies, or autoimmune or inflammation conditions. It may help by improving how doctors understand these disorders and by matching families with possible genetic diagnoses.
This research study investigates why some people have weak or poorly functioning immune systems. By studying you and your relatives, researchers hope to identify genetic factors that cause these conditions and eventually develop better treatments.
This study collects blood (and sometimes related samples) to learn how genes and the immune system work in people with primary immunodeficiency (PID) or in family members who may not have it. The goal is to improve understanding of rare immune conditions and help guide future care.
