One hundred healthy infants enrolled as controls in a tuberculosis vaccine study in Nyanza Province, Kenya provided anonymized samples for DNA sequence-based typing at the HLA-A, -B, -C, -DPB1, -DQA1, -DQB1, -DRB1, and -DRB3/4/5 loci. The purpose of the study was to characterize allele frequencies in the local population, to support studies of T cell immunity against pathogens, including Mycobacterium tuberculosis. There are no detectable deviations from Hardy Weinberg proportions for the HLA-B, -C, -DRB1, -DPB1, -DQA1 and -DQB1 loci. A minor deviation was detected at the HLA-A locus due to an excess of HLA-A*02:02, 29:02, 30:02, and 68:02 homozygotes. The genotype data are available in the Allele Frequencies Net Database under identifier 3393.
在肯尼亚尼扬扎省一项结核病疫苗研究中,100名健康婴儿作为对照参与研究,他们提供了匿名样本,用于对HLA - A、- B、- C、- DPB1、- DQA1、- DQB1、- DRB1和 - DRB3/4/5位点进行基于DNA序列的分型。该研究的目的是确定当地人群的等位基因频率,以支持对包括结核分枝杆菌在内的病原体的T细胞免疫研究。HLA - B、- C、- DRB1、- DPB1、- DQA1和 - DQB1位点未检测到偏离哈迪 - 温伯格比例的情况。在HLA - A位点检测到轻微偏差,原因是HLA - A*02:02、29:02、30:02和68:02纯合子过多。基因型数据可在等位基因频率网络数据库中通过标识符3393获取。
