摘要：The gene family of the T cell immunoglobulin and mucin domain (TIM) proteins encodes cell surface receptors that are involved in the regulation of Th1- and Th2-cell-mediated immunity. TIM-1 gene has been found to be associated with asthma in several populations. TIM-4, the natural ligand for TIM-1, may influence the susceptility to asthma.To investigate the association of the TIM-4 gene polymorphisms with asthma in a Chinese Han population. Three single nucleotide polymorphisms (SNPs) in TIM-4 gene, rs6882076, rs12658558 and rs4702747, were genotyped in 551 unrelated asthma patients and 549 healthy controls. We found that two SNPs of the TIM-4 gene, rs6882076 and rs4702747, were associated with asthma susceptibility in our study population (with P-values = 0.009 and 0.005 respectively). No association was observed between asthma and rs12658558. Our results suggest that TIM-4 gene polymorphisms are associated with asthma in a Chinese Han population.
