Abstract

Historical accounts of sickle cell disease tend to emphasize either its theoretical role in catalyzing the field of medical genetics or its clinical and social significance in representing the health-care disparities experienced by African Americans. This essay bridges these narratives by focusing on the discovery of sickle cells in marginalized Arabic-speaking communities of Yemen and Turkey in the 1950s. As in North America, sickle cell research in the Middle East unfolded along the social fractures of race. The essay analyzes how British, Turkish, and Arab geneticists attempted to create evolutionary hypotheses that reconciled historical and sociological boundaries between white and African, Arab and Turk. As the parameters of Turkish and Arab nationalism shifted in the Cold War–era Middle East, so did the favored explanatory narratives for the presence of sickle cells in different communities, which assigned different degrees of importance to African ancestry, socially enforced endogamy, and evolutionary adaptations to malaria.
