Immunoglobulin deficiency is characterized by normal total antibodies levels, but a certain antibody class is deficient. Immunoglobulin A (IGA) is the most common deficiency. Selective immunoglobulin is in some cases familial, but more frequently happens without an apparent cause.

Selective immunoglobulin A deficiency may also be caused by using antiseizure drug called Phenytoin. Most individuals with selective immunoglobulin A (IGA) deficiency have no or little noticeable problems, but other people may develop allergy and chronic respiratory infections.

Some individuals with this disorder produce anti-immunoglobulin A (IGA) antibodies if they are given LGA, containing blood transfusion, immune globulin, and plasma, which can cause severe allergic reactions the next time they are receiving immunr globulin or plasma dose.

Wearing a Medic Alert Bracelets may alert the doctor to take precaution against reaction. Generally, no treatment for Immunoglobulin A (IGA) deficiency required. Antibiotics may be prescribed to individuals with repeated infections.
