Summary

This study aims to collect blood, saliva, urine, stool, or other samples from up to 3000 people with primary immunodeficiency (PID) or their relatives. Researchers will analyze the samples to find genetic and immune system abnormalities that cause PIDs. No treatment is given; the goal is to better understand these inherited conditions and potentially identify participants for future studies.
