Hemoglobinopathies Due to Abnormal Functional Properties of Hemoglobin Molecule Part III. Stable and Unstable Abnormal Hemoglobins with Altered Oxygen Affinity

Stable abnormal hemoglobins of high oxygen affinity causing erythrocytosis and those unassociated with erythrocytosis were dealt with in the first and the second parts of this review article. In the present paper, which forms the third and the last part, hemoglobin variants with altered oxygen affinity which cause either cyanosis or not, and unstable hemoglobins with altered oxygen affinity are described
