Objective:To investigate the molecular epidemiological characteristics of abnormal Hbs in Meizhou area of Guangdong Province.Methods:A total of 15 229 people were included in this hemoglobin electrophoresis screening.Samples of 2 ml EDTA-K2 blood were analyzed by Sysmex XT-1800i blood analyzer;thalassemia genotypes and Hb E variant were identified by gap-PCR and/or reverse dot blot(RDB).The genotypes of Hb variants were detected by PCR and sequencing.Results:The incidence of abnormal Hbs was 0.479%(73/15 229).Totally
10 kinds of abnormal hemoglobin were found including 1 case of Hb J-Broussais
7 cases of Hb J-Bangkok
4 cases of Hb Wenchang-Wuming
12 cases of Hb K-NewYork
13 cases of Hb Q-Thailand
2 cases of Hb Queens
12 cases of Hb G-Chinese
1 case of Hb G-Waimanalo
3 cases of Hb G-Siriraj
and 18 cases of Hb E.Conclusion:The incidence of abnormal Hbs of Meizhou area is higher than the average incidence of China.It shows a genetic characteristic of gene flow confluence of the north and south of China.
