[Rare hemoglobins in Ivory Coast and West Africa].

Detection of drepanocytosis, which affects 12 p. 100 of the people living in Ivory Coast, is a part of the routine check up performed in hospitals. In 13 years of screening, electrophoresis has been carried out on about 170,000 samples. This work has led the authors to the typing of a certain number of uncommon hemoglobins (277 cases). As the technical methods have been greatly improved over the past few years, it is most likely that new hemoglobin mutants will continue to be discovered. A special interest of their typing consists in the fact these hemoglobins seem to be found either within specific areas or in special ethnic groups.
