基诺族、布朗族和拉祜族的4种红细胞血型分布

DISTRIBUTION OF FOUR RED CELL BLOOD GROUP SYSTEMS IN JINO,BLANG AND LAHU ETHNIC GROUPS

调查了云南基诺族、布朗族和拉祜族各 1 0 0人的 ABO、Rh、MN和 P血型系统。结果表明 ,ABO血型系统中 p基因频率拉祜族最高 ( 0 .2 4 2 0 ) ,基诺族最低 ( 0 .0 779) ,布朗族居中( 0 .2 1 44 )。 r基因频率是基诺族最高 ( 0 .6971 ) ,拉祜族最低 ( 0 .52 88) ,布朗族居中 ( 0 .5964)。Rh血型系统中 ,基诺族和拉祜族都是以 CCDee和 Cc DE-为常见类型 ,而且都是 CCDee最高 ,Cc DE-次之。拉祜族和基诺族的 CDe频率分别为 0 .7433和 0 .6950 ;c DE频率分别为 0 .1 871和0 .2 51 7;基因频率 d为零。MN血型系统中 ,这 3个民族都是基因频率 m>n。P血型系统中 ,本次调查的 3个民族的 p1基因频率在全国已调查过的汉族和少数民族中均是最高值 (拉祜族0 .50 99,布朗族 0 .4690 ,基诺族 0 .4359)

A survey on the distribution of 4 red cell blood group systems, including ABO,Rh,MN and P, was carried out in 1997 on the Jino,Blang and Lahu ethnic groups in Yunnan Province, China. One hundred students from each of the three ethnic groups (Jino in Jinghong City; Blang in Menghai County; Lahu in Lancang County) were investigated. All students investigated were unrelated, their parents and grandparents were of the same ethnic groups. The results showed that in ABO system, the gene frequency p was 0 2420(Lahu), 0 2144(Blang) and 0 0779(Jino); gene frequency r was 0 6971(Jino),0 5964(Blang)and 0 5288(Lahu). In Rh system, the most common phenotype was CCDee in both Jino and Lahu ethnic groups (56% in Lahu; 47% in Jino), and CcDE was also common (37% in Jino; 27% in Lahu). The phenotype CCDE was not observed in Jino and Blang while the phenotype ccDee was not observed in Blang and Lahu. The gene frequency of CDe was the highest among all haplotypes, 0 7433 for Lahu and 0 6950 for Jino and the gene frequency of cDE was the next, 0 2517 for Jino and 0 1871 for Lahu. No case of Rh negative was observed in all of the three ethnic groups. In MN system, gene frequency m>n was observed in all of the three ethnic groups. In P system, the gene frequency P 1 was 0 5099(Lahu),0 4690(Blang) and 0 4359(Jino),respectively. All these figures are higher than those of any other ethnic groups investigated all over the country.
