Sickle cell anemia is an autosomal hereditary disorder in which erthrocytes become sickle shaped. The disorder is caused by formation of an abnormal haemoglobin called haemoglobin -S. As found out by Ingram, haemoglobin -S differs from normal haemoglobin-A in only one amino acid -6th amino acid of beta -chain, glutamic acid replaced by valine. During conditions of oxygen deficiency 6- valine forms hydrophobic bonds with complementary sites of other globin molecules. It distorts their configuration. As a result, erythrocytes having haemoglobin -S become sickle shaped and thus they are protected against malaria because of their particular haemoglobin mutation.
