Background: Inherited disorders of hemoglobin are the most common gene disorders worldwide. The objective of this study is to determine the frequency distribution of hemoglobin variants among the Yorubas residing in Ibadan. Materials and Methods: Five hundred and thirty one subjects comprising 184 males and 347 females, of age 1-70 years, were enrolled in the study. Ethical approval was obtained from the Ethical Committee of the University College Hospital and a duly signed informed consent was obtained from each subject. Two milliliters of venous blood was aseptically collected from each participant for the determination of hemoglobin genotype, using the standard hematology method. Results: Hemoglobin HbAA recorded the highest frequency distribution (65.3%). This was followed by hemoglobin variant HbAS (24.1%), abnormal hemoglobin variant HbSS (5.5%), HbAC (4%), and HbSC (1.1%), (P > 0.05). The female subjects revealed higher frequency distributions of AA, AS, SS, and SC, while the male demonstrated higher frequencies in AC and SC only. Conclusion: It can be concluded that the Yoruba indigenes residing in Ibadan have a high frequency distribution of HbAA and a future reduction in the HbSS disease in the populace is possible. |
