Natural history study for severe combined immune deficiency (SCID)
Part of Genetic & congenital, Hormones & metabolism, Immune system & allergy clinical trials.
This study follows children and adults with SCID and related immune disorders to understand how the illness behaves over time. It also helps researchers learn which testing results and genetic types of SCID match different treatment plans.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You (or your child) have SCID or a related condition that doctors classify as one of the SCID “types” the study studies
- Blood testing shows the T-cell immune part is missing or severely weak (the exact lab cutoffs depend on the SCID type)
- Your doctor plans a specific SCID treatment path (for example, transplant, PEG-ADA replacement medicine, or gene therapy)
- If this is “typical” SCID: either T cells are very low, T-cell function is very low, or T cells came from the mother
- If this is Omenn syndrome or “leaky” SCID: specific lab and symptoms (like rash for Omenn) and maternal cell testing must fit the study’s rules

This study tests a gene therapy to treat X-linked severe combined immunodeficiency (X-SCID) without a stem cell transplant from a matched sibling. It aims to improve immune function and reduce infections using your own stem cells modified to carry the correct gene.
This trial tests a stem cell transplant to treat common variable immunodeficiency (CVID) and other immune problems. It aims to replace a faulty immune system with a healthy one from a donor.
This early-phase study tests a step-by-step transplant approach: first replacing the lungs, then doing a bone marrow (stem cell) transplant to treat certain immune deficiency diseases. It may help people whose immune problem has led to severe, end-stage lung disease.
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 follows babies who had a positive newborn screening test for severe combined immunodeficiency (SCID), a rare condition affecting the immune system. The goal is to monitor their health over time to better understand and manage the condition.
This trial tests a one-time gene therapy approach to help children with X-linked SCID (a serious inherited immune disorder) make better immune cells. It’s for people who don’t have a fully matched sibling donor and need long-term follow-up after treatment.
