Primary immunodeficiencies (PIDs), also known as inborn errors of immunity (IEI) are a group of more than 400 potentially serious disorders that can lead to frequent or severe infections, swellings and autoimmune problems. PID/IEI discorders can be caused by defects in genes that control the immune system, and may be inherited.
