Summary

This study looks for the genetic causes of inherited immune system problems that affect white blood cell balance. It involves up to 5,000 people with suspected immune disorders and their relatives. Researchers will review medical records and collect blood samples to identify disease-related genes. The goal is to better understand these conditions, not to provide direct treatment.
