Abstract
In this study we report three cases of Hb Ube-1, one case of Hb Ube-2 and one case of Hb Ube-4 in mainland China. One case of Hb Ube-1 had the clinical manifestation of hemolytic anemia. Hb Ube-2 and Hb Ube-4 did not appear to be associated with clinical or hematological abnormalities. The variants were detected by Hb electrophoresis during a thalassemia screening. Genomic DNA was extracted from the peripheral blood leukocytes of Hb specimens. α1, α2 and β-globin genes were amplified by polymerase chain reaction (PCR). All variants were confirmed by DNA sequence analy-sis and the PCR-restriction fragment length polymorphism assay.
