利用白细胞抗原(HLA)的高度多态性,研究我国各少数民族与汉族之间及少数民族相互之间的关系可以看出HLA基因流动的方向。通过有计划的调查,有可能绘出我国各民族HLA频率分布地图,这不仅对医学而且对多种学科均有重要意义。过去从未有过我国不同地区、不同民族人群的HLA分布的资料。我们在测得北京地区汉族人群HLA分布的基础上,进入少数民族腹地,对我国广
Using the high degree of polymorphism of leukocyte antigen (HLA), we can find out the direction of HLA gene flow by studying the relationship among ethnic minorities in our country, Han nationality and ethnic minorities. Through a planned survey, it is possible to map the HLA frequency distribution maps of all ethnic groups in our country, which is of great significance not only for medicine but also for many disciplines. In the past, there have never been any HLA distributions in different ethnic groups across China. Based on the measurement of HLA distribution in the Han nationality in Beijing area, we entered the hinterland of minority nationalities,
