A patient with "heavy-chain disease" of the mu-chain variety is described. A syndrome of mu-chain disease may have been characterized in this and two previously reported cases as slowly progressive chronic lymphocytic leukemia with prominent hepatosplenomegaly, with pathologic fractures, and with apparent hypogammaglobulinemia, Bence-Jones proteinuria, and an abnormally negatively charged IgM fragment on serum immunoelectrophoresis. Evidence in this case is consistent with in vitro studies that suggest that the biochemical defect in mu-chain disease is a lack of normal coupling of light and heavy chains in the biosynthetic cells, rather than an over-production of heavy chains, as is the case in alpha and gamma heavy-chain diseases.
