20,000 volunteers needed to decode immune disease genetics
NCT ID NCT03206099
First seen Jun 24, 2026 · Last updated Sep 17, 2026 · Updated 28 times
Summary
This study will analyze DNA from up to 20,000 people, including those with immune disorders and their relatives, to find genetic variants linked to conditions like atopy, autoimmunity, and primary immunodeficiency. Researchers will also study how best to return genetic results to participants. The goal is to better understand the genetics of these diseases and improve clinical genetic services.
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 could help identify new genetic causes of immune disorders and improve how genetic results are shared with patients.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly benefit participants, and some genetic findings may be uncertain or not actionable.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
* PARTICIPANT INCLUSION CRITERIA: * Must fulfill one of the following criteria: * Proband participants: must be individuals under investigation by another NIH protocol on which they are co-enrolled, or are referred from the GDMCC protocol "Defining the Genetic Etiology of Suppurative Lung Disease in Children and Adults" (NCT04702243). Probands may have a disease under investigation or be healthy volunteers * Biological relatives: biologically related to a proband participant. * Aged 0-99 years. * Participants must be willing to undergo genetic testing. * Participants must be willing to allow samples to be stored for future research. * Participants must be willing to have their de-identified genomic data shared, for example in a controlled access databases like the Database of Genotypes and Phenotypes (dbGaP). * To complete surveys and interviews: * Proficient with the English language. * Able to provide informed consent. * Adult healthy volunteers must be able to provide informed consent. PARTICIPANT EXCLUSION CRITERIA: Any condition that, in the opinion of the investigator, contraindicates participation in this study is a reason for exclusion.
