Tracking lymph node and immune cell growth in rare immune disorders
Part of Blood & lymphatic, Genetic & congenital, Immune system & allergy clinical trials.
This study follows patients with rare inherited immune disorders who develop enlarged lymph nodes, swollen spleen, or lymphoma over time. Researchers want to understand how these conditions develop and progress to improve care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a confirmed diagnosis of a rare inherited immune disorder (primary immunodeficiency)
- You have or had swollen lymph nodes, enlarged spleen, or lymphoma linked to your immune disorder
- Your lymph node or immune cell growth was diagnosed between January 2014 and December 2025
- You have been followed at one of the study hospitals in France for at least 12 months after diagnosis
- You are not dealing with HIV, recent chemotherapy, or a transplant that weakened your immune system

This research study helps doctors understand ALPS, a rare immune disorder that causes swollen lymph nodes and spleen. Participating means providing blood samples and health information so researchers can learn how the condition develops and how to better care for patients.
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 study screens people who may have an inherited immune system condition (like problems with immune cell growth or death) and their blood relatives. The goal is to understand the condition better by collecting blood samples for testing.
This trial tests a tool (a way of collecting health information) to help doctors make better diagnosis, prognosis, and treatment decisions for children with certain immune problems. It also includes healthy children (like relatives) as comparison groups, to see how well the tool works.
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.
This study collects information from patients with lymphoproliferative disorders—conditions affecting blood and lymph cells—to help doctors better understand these diseases and improve care. Your medical records and information may be used to support research that could benefit future patients.
