[目的]了解山东临沂汉族人群HLA-A、B、DRB1等位基因分布特征。[方法]采用聚合酶链反应-序列特异性寡核酸探针方法(PCR-SSOP)对4035份山东临沂地区汉族人进行HLA分型。计算HLA等位基因频率,并与辽宁省、山东省、重庆市、海南省汉族人群HLA等位基因频率进行比较。[结果]共检出HLA-A、B、DRB1位点等位基因63种,其中基因频率高于10%的分别是:A*02(27.3978%)、A*24(14.6240%)、A*11(14.2131%)、A*30(11.5861%)、A*33(11.5613%)、B*13(15.8736%)、B*15(12.9864%)、B*40(11.5118%)、DRB1*15(18.3271%)、DRB1*07(15.3160%)、DRB1*04(10.7683%),其中A*02、A*11、A*24、A*30、A*33、B*07、B*13、B*15、B*40、B*44、B*46、DRB1*07、DRB1*09、DRB1*12、DRB1*13、DRB1*14等位基因频率与中国其他地区汉族人群比较差异有显著性意义(P<0.005)。[结论]山东汉族临沂地区汉族人群HLA-A、B、DRB1等位基因分布具有高度多态性并且具有自身的分布特点。 |

Abstract: |
[Objective]To study the distribution of HLA-A,B,DRB1 alleles in Shandong Linyi Han population.[Methods]All the donors’ HLA typing,in Shandong Linyi,were done with PCR-SSOP.Then the alleles frequency was analyzed and compared with other populations.[Results]The alleles of 63 cases were observed at HLA-A,B,DRB1 loci.The dominant alleles which alleles frequency beyond 10% were A*02(27.3978%), A*24(14.6240%), A*11(14.2131%), A*30(11.5861%), A*33(11.5613%), B*13(15.8736%), B*15(12.9864%), B*40(11.5118%), DRB1*15(18.3271%), DRB1*07(15.3160%) and DRB1*04(10.7683%).The alleles’ distributions in A*02,A*11,A*24,A*30,A*33,B*07,B*13,B*15,B*40,B*44,B*46,DRB1*07,DRB1*09,DRB1*12,DRB1*13 and DRB1*14 differ from those in other districts China(P<0.005).[Conclusion]The distributive characteristics of HLA-A,B,DRB1 alleles in Shandong Linyi Han population were found. |
