Evolving field of (new) primary immunodeficiencies in humans. Developed in 1970 under the auspices of the World Health Organization (WHO) following an initiative of Drs Fudenberg, Good, Hitzig, Kunkel, Roitt, Rosen, Rowe, Seligmann, and Soothill. Now monitored and updated biannually by the International Union of Immunological Societies.


See Table P-5. Primary Immunodeficiencies are classified into combined immunodeficiencies, combined immunodeficiencies with syndromic features, predominantly antibody deficiencies, diseases of immune dysregulation, defects of phagocyte number or function, defects in intrinsic and innate immunity, lists autoinflammatory diseases, complement deficiencies, and phenocopies of inborn errors of immunity.
