To investigate the molecular diagnosis of hemoglobin variants in Z region by Capillary electrophoresis in Central Guangxi, Southern China, and analyze their distribution and phenotypic characteristics, to provide a reference for clinical consultation and prenatal diagnosis for couples. A total of 23,709 subjects were collected for blood routine analysis, hemoglobin analysis, and common α- and β-globin gene loci in Chinese population. The hemoglobin electrophoresis components were divided into Zone 1-Zone 15 (Z1-Z15) by Capillary zone electrophoresis (CE). For samples not clearly detected by the conventional technology, Sanger sequencing, and multiplex ligation-dependent probe amplification (MLPA) were used. Single-molecule real-time (SMRT) sequencing technology was used to analyze rare-type genes in a sample with a structural variation. Ten rare hemoglobin variants distributed in Z region were detected in 23,709 samples, including Hb Cibeles, which was reported for the first time in Asia; Hb J-Broussais, Hb G-Honolulu and J-Wenchang-Wuming, they were first reported in Guangxi; 1 case of Hb Anti-Lepore Liuzhou, which was a newly discovered hemoglobin variant; hemoglobin variants Hb G-Siriraj, Hb Handsworth, Hb Q-Thailand, Hb Ube-2, Hb NewYork were also detected. There are a few studies on rare hemoglobin variants in Z region in Southern China. Ten rare hemoglobin variants were found in this study. The hematological phenotype and component content of hemoglobin variants are related to the occurrence of thalassemia. This study enriched the data of rare hemoglobin variants in Southern China and provided a comprehensive data basis for prenatal diagnosis of hemoglobin variants in this area. [ABSTRACT FROM AUTHOR] |
