Abstract
Hb Korle Bu (β73 Asp → Asn) is believed to have had its origin in West Africa (1,2). This mutant has also been identified among the black population of the United States (3), as well as in the West Indies (4,5) and South America (6). In this communication we report the identification of Hb Korle Bu in a Mexican Indian family from Durango, and in addition we describe an easy and specific method for confirming the presence of this variant.
