In addition to HLA-B27, other genetic factors are thought to be involved in the pathogenesis of ankylosing spondylitis (AS). Because of the localization, in the proximity of the HLA-B locus, and the biological activities of TNF-alpha, we investigated the association between AS and a single base polymorphism located at position -308 of the TNF-alpha gene. An allele-specific polymerase chain reaction was developed to monitor this polymorphism. The frequency of the TNF-alpha alleles was determined in 66 AS patients and 37 healthy controls. The TNF-alpha allele frequency was not significantly different between AS patients and controls.
除HLA - B27外,其他遗传因素也被认为与强直性脊柱炎(AS)的发病机制有关。由于肿瘤坏死因子-α(TNF-α)的定位靠近HLA - B基因座且具有生物学活性,我们研究了AS与位于TNF-α基因-308位的单碱基多态性之间的关联。我们开发了一种等位基因特异性聚合酶链反应来监测这种多态性。在66例AS患者和37例健康对照中测定了TNF-α等位基因的频率。AS患者和对照组之间的TNF-α等位基因频率无显著差异。
