Hemoglobin H is of particular interest since it consists only of j3 chains (1). This abnormal hemoglobin, therefore, presents a unique opportunity for investigating the imluence of a-j3 chain interactions on some of the structural and functional properties of hemoglobin. The hemoglobin H used for these studies was obtained from two patients. The first patient, L. G., was a 25-year-old woman of ...

Hemoglobin E is very common in parts of Southeast Asia. The possible malaria protective effects of this and other inherited hemoglobin abnormalities prevalent in Thailand were assessed in a mixed erythrocyte invasion assay. In vitro, starting at 1% parasitemia, Plasmodium falciparum preferentially invaded normal (HbAA) compared to abnormal hemoglobin (HbH, AE, EE, HCS, beta-thalassemia E) red c...

A Chinese family with hemoglobin H in the propositus has been reinvestigated. Although the original propositus is now deceased, a sister has the same hematological manifestations. Her hemoglobin, like that of the deceased sister, contains hemoglobins A, H, and Bart's. In addition, however, two minor components have been detected. These minor components appear to have abnormal alpha-chains and a...
