Question

Quizplus · Accepted Answer

Multiple myeloma is a cancer of the plasma cells, which secrete abnormal amounts of monoclonal immunoglobulin (or light chains) that can be detected in the urine, leading to a condition called Bence Jones proteinuria. Waldenström's macroglobulinemia is another immunoproliferative disorder that involves excessive production of a different type of immunoglobulin (IgM). Alpha heavy chain disease is a rare immunodeficiency disorder characterized by systemic infections and malabsorption due to a deficiency in the production of alpha-heavy chains. DiGeorge syndrome is a genetic disorder that affects the development of multiple organs and is not related to immunoproliferative disorders.
