Summary

This study screens up to 2,000 people who have or may have a weak immune system that makes them prone to infections, along with their healthy blood relatives. The goal is to find the causes of these immune problems and improve how they are diagnosed and treated. Participants undergo medical history, physical exams, blood tests, and other evaluations, but this study does not provide treatment—it identifies candidates for future research studies.
