Primary Immunodeficiency

📖What is Primary Immunodeficiency?

Primary Immunodeficiency refers to a group of over 400 rare, genetically inherited disorders in which part of the immune system is missing or functions improperly, leaving affected individuals more vulnerable to infections, autoimmune disease, and certain cancers. Unlike secondary immunodeficiencies caused by external factors like HIV or medications, these conditions result from inborn errors in immune system genes present from birth. Severity ranges widely from mild forms that cause occasional infections to severe combined immunodeficiencies that are life-threatening in infancy without treatment. Early diagnosis and specialized care significantly improve outcomes and quality of life.
