      subgroup of the blood proteins called globulins. In humans and many of the other mammals, antibodies, when they are formed, occur in the gamma globulins. Persons who lack gamma globulin or who have an inadequate supply of it—conditions called, respectively, agammaglobulinemia and hypogammaglobulinemia—have frequently recurring infections because of their inability to develop adequate immunity to infectious diseases.
