摘要
目的 :检测HLA Cw在广东汉族人群的分布频率 ,初步分析该人群中KIR与HLA Cw之间识别方式的特点及意义。方法 :骨髓移植供者 12 2例 ,ACD抗凝血提取DNA ,半量全自动PCR RSSO分型检测Cw。结果 :广东汉族人群HLA Cw基因频率分布由高至低依次为 :Cw 0 3(0 2 371) >Cw 0 7(0 2 15 9) >Cw 0 1(0 175 2 ) >Cw 0 8(0 112 9) >Cw 0 4 (0 0 5 0 5 ) >Cw 14、15(0 0 4 19) >Cw 12 (0 0 376 ) >Cw 0 6 (0 0 333) >Cw 0 5 (0 0 0 82 ) >Cw 16 (0 0 0 4 1)。第一组Cw 0 2 ,0 4 ,0 5 ,0 6识别KIR分子中2DL 2DSI;第二组Cw 0 1,0 3,0 7,0 8识别KIR分子中 2DL2 2DL3;2DS2 2DS3。两组分布频率相比有显著性差异 (P <0 0 1)。结论 :广东汉族人群HLA Cw 0 1,0 3,0 7,0 8出现频率较高 ,其与KIR的识别方式均属第二组。
Objective:To explore the gene frequencies of HLA-Cw and to analyze the recognition characteristic between HLA-Cw and KIR in Guangdong Han population.Methods:An auto semi-quantitative PCR-RSSO method was adopted to detect the HLA-Cw genotypes of a sample of 122 bone marrow donors.Results:The gene frequencies of HLA-CW 03,07,01,08,04,14,15,12,06,05,16 were 0.237 1 , 0.215 9 , 0.175 2 , 0.112 9 , 0.050 5 , 0.041 9 , 0.041 9 , 0.037 6 , 0.033 3 , 0.008 2 , 0.004 1 respectively.HLA-Cw 02,04,05,06 belong to “group 1” recognizing KIR-2DL1/2DS1.HLA-Cw 01,03,07,08 belong to “group 2” recognizing KIR-2DL2/2DL3;2DS2/2DS3.There was a significant difference between the two groups in total HLA-Cw gene frequencies in Guangdong Han population( P<0.01 ).Conclusion:HLA-Cw 03,07,01,08 gene frequencies show higher in Guangdong population.All of them belong to “group 2” in KIR recognition.
