Overview

Common variable immunodeficiency is an immune system disorder that causes you to have low levels of the proteins that help fight infections. If you have this condition, you'll likely have repeated infections in your ears, sinuses, and respiratory system. You'll also have an increased risk of digestive disorders, blood disorders, and cancer. The condition can be inherited, or you can develop it during your lifetime.

Symptoms

Symptoms of common variable immunodeficiency may appear during childhood or adolescence, though many people don't experience them until adulthood. If you have this condition, you'll likely have repeated infections in your ears, sinuses, and respiratory system.
