IgA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA).Antibodies are large proteins produced by the body to fight infections caused by invaders, such as bacteria, viruses, fungi, parasites, and other foreign agents.gA is found in the saliva, mucous membranes, and intestinal secretions, where it may serve as the first line of defense against various sinus, respiratory, and gastrointestinal infections. Consequently, a deficiency of IgA heightens oneâs vulnerability to such infections.
