Summary
This study screens up to 2,000 people who have or may have immune disorders that make them prone to infections, along with their healthy relatives. Researchers will use medical history, physical exams, blood tests, and genetic testing to better understand these conditions. The goal is to improve diagnosis and guide future research, not to provide treatment directly.
