Summary
This study aims to learn more about primary immunodeficiency disorders (PIDs), which weaken the immune system and make people more prone to infections. Researchers will compare genetic and health data from people with PIDs, their healthy relatives, and healthy volunteers to find genetic causes and new disease patterns. Up to 2,500 participants aged 0 to 90 will be followed for up to 10 years with annual check-ins and blood draws.
