Abstract: Hemoglobin D-Punjab has been observed in several ethnic groups, either in heterozygosis or in association with Hb S or β-thalassemia. In this report, we describe the case of a 10 year-old Black Brazilian girl who presented the classical, clinical and hematological features of sickle cell disease, but whose hemoglobin electrophoretic profile suggested the association Hb S/Hb D. The Hb D mutation was confirmed by EcoRI digestion of the PCR amplified β globin gene and by sequencing of the resulting fragment. The mutation involves a simple base change at codon 121 which eliminates a normal EcoRI site. The abnormal gene can be detected by agarose gel electrophoresis. This finding represents the second proven case of Hb S/Hb D association in Brazil. We suggest that Hb D should be investigated by PCR techniques in sickle cell disease patients presenting an anomalous hemoglobin electrophoretic profile.
