Hereditary Hemolytic Anemia with Triosephosphate Isomerase Deficiency

Abstract

THE demonstration of the association of inherited deficiencies of erythrocyte enzymes with certain congenital hemolytic anemias has aided a greater understanding of the genetic and pathological manifestations of these disorders, and has resulted in a more definitive classification of these heterogeneous conditions. In 1954 Selwyn and Dacie¹ separated the congenital nonspherocytic hemolytic anemias into two classes, Types 1 and 2, on the basis of differences in the spontaneous autohemolysis of sterile defibrinated blood. Valentine, Tanaka and Miwa,^{2 , 3} in 1961, described the occurrence of a marked deficiency of erythrocyte pyruvate kinase in association with hemolytic disease classifiable as Type 2 on . . .
