In 1949, the discovery that sickle hemoglobin ({alpha}2 {beta}S2) has an abnormal electrophoretic mobility prompted Linus Pauling and his colleagues to christen sickle cell anemia "a molecular disease."1 The ensuing five decades have produced a wealth of information on the mechanisms by which a single base substitution in the gene encoding the human {beta}-globin subunit, with the resulting replacement of {beta}6 glutamic acid by valine, leads to the protean and devastating clinical manifestations of sickle cell disease. Until recently there was a disappointing lag in the application of this knowledge to the design of safe and effective forms of therapy. . . . [Full Text of this Article]
