Severe combined immunodeficiency (SCID) (also known as Alymphocytosis Glanzmann–Riniker syndrome Severe mixed immunodeficiency syndrome and Thymic alymphoplasia) is a genetic disorder characterized by the absence of functional T-lymphocytes which results in a defective antibody response due to either direct involvement with B lymphocytes or through improper B lymphocyte activation due to non-functional T-helper cells.
