We present a new abnormality of the red cell membrane observed in the course of a study on beta-thalassemia. In a child suffering from a beta 0-thalassemia major, the neutral membrane bound phosphatase, instead of having Michaelis-Menten kinetics, displayed a biphasic kinetics consistent with inhibition by substrate excess. This abnormality is discussed along with other erythrocyte membrane alterations that are known to occur in beta-thalassemia.
