Severe Combined Immunodeficiency (SCID) is a group of rare congenital syndromes characterized by little if any immune responses. This results in frequent recurring infections. Cellular immune responses involve specialized white blood cells known as T lymphocytes or "killer cells". These cells assist other white blood cells (B lymphocytes) to respond to infectious, foreign agents that invade the body (i.e., bacteria or viruses). The B lymphocytes maintain immunity by enabling the body to produce and preserve circulating antibodies.
People with Severe Combined Immunodeficiency are unusually susceptible to recurrent infections with bacteria, viruses, fungi, and other infectious agents that can be life-threatening.
There are several types of Severe Combined Immunodeficiencies. These include: Autosomal Recessive Severe Combined Immunodeficiency, X-Linked Recessive Severe Combined Immunodeficiency, Adenosine Deaminase Deficiency (ADA), Bare Lymphocyte Syndrome, Severe Combined Immunodeficiency with Leukopenia (Reticular Dysgenesis), and Swiss-type Agammaglobulinemia. Each type of Severe Combined Immune Deficiency is caused by a different genetic defect, but the primary symptom is reduced or absent immune functions, and all types are hereditary.
