1 IgG deficiency with hyper-IgM is a disease that results when the B-cell fails to switch from making IgM to IgG. 2  This produces an increase in the amount of IgM antibodies present and a decrease in the amount of IgG antibodies. 3  This disease is the result of a genetic mutation.
Selective IgA Deficiency is defined as a primary immunodeficiency characterized by an undetectable level of immunoglobulin A (IgA) in the blood and secretions but no other immunoglobulin deficiencies. There are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.IgG is present in the largest amount, followed by IgM and IgA. IgD is much lower, and IgE is present in only minute amounts. IgM and IgG mainly protect us from infections inside our body tissues, organs and blood.here are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.
