通过对已有研究结果的检索,调查HIV-1感染相关等位基因CCR2-64 I在我国人群中的频率和多态性分布。通过对检索结果的汇总发现,CCR2-64 I在中国29个民族群体中的分布存在种族和地域差异,不存在明显地域上的趋势性变化,多数民族突变频率明显高于美国白人和高加索人,与美国黑人和西班牙人比较接近,但多数明显低于亚洲黄种人水平。部分研究结果可靠性较差。 Through the search of existing research results, investigate the frequency and polymorphism distribution of CCR2-64 I allele associated with HIV-1 infection in our population. Through the comparisons of the search results, we found that the distribution of CCR2-64 I in the 29 ethnic groups in China has racial and geographical differences. There is no obvious regional trend change. The mutation frequencies of the majority of ethnic groups are significantly higher than that of the white and Caucasian Caucasians, Close to African Americans and Hispanics, but most of them are significantly below the Asian yellow. Some of the findings are less reliable.
