Types of SCID are classified by which immune cells, T, B, and/or NK cells, are defective.

Patients with SCID have a genetic defect that affects T cells and at least one other type of immune cell (hence “combined immunodeficiency”). Natural killer (NK) cells are specialized to help fight viruses as well. B lymphocytes (B cells) produce antibodies that attach to invaders and mark them to be destroyed, but they need T cells to work effectively. These white blood cells include T lymphocytes (T cells) that are central mediators of the immune response and also directly attack viruses. The immune system includes specialized white blood cells that work together to fight off bacteria, fungi, and viruses. Infections that are minor in most people can be life‑threatening in people with SCID. This results in frequent recurring infections with bacteria, fungi, and viruses. Severe combined immunodeficiency (SCID) is a group of rare congenital syndromes with little or no immune responses.
