HB D Los Angeles in a Brazilian family

Hb D Los Angeles em família brasileira

Inherited disorders of hemoglobin, the most common monogenic disease, are now well understood at the molecular level, knowledge, which has led to considerable improvements in their control and management. The Brazilian population is multiethnic, and the correct characterization of the Hb D is important, mainly because the method available for detection of abnormal hemoglobins, present a migration in the same zone at alkaline pH, for Hb S, D, and G for example. In this paper we studied a family with an abnormal hemoglobin like S in alkaline electrophoresis, by appropriated methods including HPLC and molecular analysis, characterized as hemoglobin D Los Angeles.
