Hypogammaglobulinemia is a type of immune disorder characterized by a reduction in all types of gamma globulins.[1]
Hypogammaglobulinemia is a characteristic of common variable immunodeficiency.[2]

"Hypogammaglobulinemia" is distinguished from dysgammaglobulinemia, which is a reduction in some types of gamma globulins, but not others.[3][4]
"Hypogammaglobulinemia" is largely synonymous with "agammaglobulinemia". When this term is used (as in "X-linked agammaglobulinemia") it implies that gamma globulins are not merely reduced, but completely absent. Modern assays have allowed most agammaglobulinemias to be more precisely defined as hypogammaglobulinemias,[5] but the distinction is not usually clinically relevant.
