对４４名西双版纳傣族和９名上海地区汉族ＤＫ２阳性个体进行了与其相关的ＤＲ／ＤＱ单倍型组合的分析。傣族群体中ＤＲＢＩ－ＤＲ２亚型分布以＊１６０２与＊１５０２为最常见，其等位基因频率分别为４３．６％与，４０．０％和汉族群体中以＊１５０１为主明显不同。傣族群体中共检出１０种与ＤＲ２相关联的ＤＲ／ＤＱ单倍型；最常见的是ＤＲＢ１＊１６０２、ＤＲＢ５＊０１０１、ＤＱＡ１＊０１０２、ＤＱＢ１＊０５０２（３４．５％）与汉族及其他群体明显不同，本研究表明傣族不仅具有高频率的ＤＲ２，而且与ＤＲ２相关联的ＤＲＢ１、ＤＲＢ５、ＤＱＡ１、ＤＱＢ１单倍型组合有其独特性。
The association of DR / DQ haplotypes was analyzed in 44 Xikangbanna Dai nationality and 9 Shanghai Han DK2 positive individuals. The distribution of DRBI-DR2 subtypes in Dai population was the most common with * 162 and * 1502 alleles, and the allele frequencies were 43.6% and 40.0%, respectively, and were significantly different from those in the Han population . There were 10 DR / DQ haplotypes associated with DR2 detected in the Dai population. The most common were DRB1 * 1602, DRB5 * 0101, DQA1 * 0102, DQB1 * 0502 (34.5%) and Han This study shows that Dai people not only have high frequency of DR2, but also have the uniqueness of DRB1, DRB5, DQA1 and DQB1 haplotype combinations associated with DR2.
