目的检测并分析延边地区朝鲜族和汉族人群ABO血型分布特征和基因频率。方法有效调查延边地区人群1416人,朝鲜族724人(男288人;女436人),汉族691人(男338人;女353人),指端或耳垂采血,抗A抗B标准血清玻片凝集法检测受检者的ABO血型。结果延边地区朝鲜族和汉族人群ABO血型分布表现型频率结果均为B>O>A>AB,基因频率结果均为r>q>p,民族指数分别为0.6517和0.8600。结论延边地区朝鲜族和汉族人群ABO血型分布特点为均具有较高的B型血频率,民族指数均小于1,具有相似的ABO血型分布特征及典型的北方人群结构特征。
Objective To detect and analyze the distribution and gene frequency of ABO blood group in Korean and Han nationality in Yanbian area. Methods A total of 1416 people in Yanbian area were surveyed, including 724 people (288 men and 436 women), 691 Han people (338 men and 353 women) in Yanbian, blood samples collected from fingertip or ear lobe, anti-A anti-B standard serum slides Agglutination test subjects ABO blood group. Results The frequency of ABO blood group phenotypes in Korean and Han nationality in Yanbian area were all B> O> A> AB. The frequency of gene frequency was r> q> p, and the nationality index was 0.6517 and 0.8600 respectively. Conclusion The distribution of ABO blood group in both Koreans and Han nationality in Yanbian area is characterized by high frequency of type B blood and ethnic index less than 1, with similar ABO blood group distribution and typical northern population structure.
