Hundreds of genetic association studies on asthma-related phenotypes have been conducted in different populations. To date, variants in 64 genes have been reported to be associated with asthma or related traits in at least one study. Of these, 33 associations were replicated in a second study, 9 associations were not replicated either in a second study or a second sample in the same study, and 22 associations were reported in just a single published study. These results suggest the potential for a great amount of heterogeneity underlying asthma. However, many of these studies are methodologically limited and their interpretation hampered by small sample sizes.
针对哮喘相关表型,已经在不同人群中开展了数百项基因关联研究。迄今为止,至少在一项研究中,已有报告称64个基因中的变异与哮喘或相关特征有关。其中,33个关联在第二项研究中得到了重复验证,9个关联在第二项研究或同一研究的第二个样本中未得到重复验证,22个关联仅在一项已发表的研究中被报告。这些结果表明哮喘背后可能存在大量的异质性。然而,这些研究中有许多在方法上存在局限性,且由于样本量小而妨碍了对其结果的解读。
