Overview
Hypergammaglobulinemia is a primary immunodeficiency disease with an elevated concentration of gamma globulins (immunoglobulins or antibodies).[1][2][3] The term "hypergammaglobulinemia" refers to the position of the excess of proteins after serum protein electrophoresis (found in the gammaglobulin region).[1] The majority of hypergammaglobulinemias are due to an excess of immunoglobulin M (IgM) because this is the default immunoglobulin type prior to class switching.[1] Hypergammaglobulinemias may also result from a deficiency in the other major types of immunoglobulins (IgA, IgE, and IgG).[1][4]
Classification
- Hypergammaglobulinemia may be classified into the following:
- Hyper IgM associated hypergammaglobulinemias are further classified into the following five types:[5][6]
