A recent genome-wide association study (GWAS) involving patients with hemophilia A who were exposed to but uninfected with human immunodeficiency virus type 1 (HIV-1) did not reveal genetic variants associated with resistance to HIV-1 infection, beyond homozygosity for CCR5-Δ32. Since variation in HLA class I and KIR genes is not well interrogated by standard GWAS techniques, we tested whether these 2 loci were involved in protection from HIV-1 infection in the same hemophilia cohort, using controls from the general population. Our data indicate that HLA class I alleles, presence or absence of KIR genes, and functionally relevant combinations of the HLA/KIR genotypes are not involved in resistance to parenterally transmitted HIV-1 infection.
最近一项全基因组关联研究（GWAS）纳入了暴露于1型人类免疫缺陷病毒（HIV-1）但未感染的甲型血友病患者，研究结果显示，除CCR5-Δ32纯合子外，未发现与HIV-1感染抗性相关的基因变异。由于标准GWAS技术对HLA I类和KIR基因变异的研究不够深入，我们利用来自普通人群的对照，在同一血友病队列中测试了这两个基因座是否参与了对HIV-1感染的保护作用。我们的数据表明，HLA I类等位基因、KIR基因的有无以及HLA/KIR基因型的功能相关组合均不参与对经肠道外传播的HIV-1感染的抗性。
