agammaglobulinemia common variable immunodeficiency Heterogeneous group of immunodeficiency syndromes characterized by hypogammaglobulinemia of most isotypes, variable B-cell defects, and the presence of recurrent bacterial infections.

It results in recurrent bacterial infections. Complications include autoimmune phenomena and cancer development. DOID:12177 COMMON VARIABL IMMUNODEF GeneRIF:15598813 GeneRIF:15817684 Acquired hypogammaglobulinaemia James Malone A hypogammaglobulinemia that is results in insufficient production of antibodies needed to respond to exposure of pathogens and is characterized by low Ig levels with phenotypically normal B cells that can proliferate but do not develop into Ig-producing cells. Patients with common variable immunodeficiency have marked reduction in serum levels of both immunoglobulin G (IgG) and immunoglobulin A (IgA); about half of these patients also have reduced immunoglobulin M (IgM).
