Here, we discuss the emerging data on the causes and consequences of neutropenia and discuss the relevance of these data for African populations, in which the prevalence of neutropenia is high. ⋯ Neutropenia among Africans, linked to the Duffy-null trait or otherwise, may have significant health consequences that remain largely undetermined and could have a significant impact on the pathogenesis of diseases.
