Quick Summary

Congenital immunodeficiency syndrome refers to defects in the immune system that are present from birth, often due to genetic mutations. These conditions impair the body's ability to fight off infections.12

Key aspects affected can include lymphocytes, leukocytes, antibodies, and the complement system. Examples include:1
* X-linked infantile agammaglobulinemia: Affects males, preventing B lymphocytes from producing all classes of antibodies.2
* DiGeorge syndrome: A T-cell deficiency caused by defective thymus development.2
* Severe combined immunodeficiency (SCID): Disrupts both T and B cell development.12
* Chronic granulomatous disease: Impairs phagocytic cells' ability to destroy pathogens.2

Treatments can involve immunoglobulin injections, bone marrow transplants, or thymus transplantation, depending on the specific condition.12
