NCT ID NCT00001355
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 5 times
Summary
This study looks at people with unusual or repeated infections and their family members to find the genetic and biochemical causes of immune system problems. Researchers will collect blood, saliva, urine, and other samples over time to better understand these conditions. The goal is to improve diagnosis and treatment for inherited immune defects.
