Haplotypes covering the TNFSF10 gene are associated with bronchial asthma.
Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is elevated in the airways of subjects with asthma and has been linked to the development of allergic airway disease by promoting STAT6-dependent T helper 2 cell (T(H) 2) effector functions. To determine whether single nucleotide polymorphisms (SNPs) in the TNFSF10 gene are associated with bronchial asthma we genotyped 498 Caucasian subjects living in Southern Germany for eight SNPs in the TNFSF10 by restriction fragment length polymorphism analysis. In contrast to single SNPs, haplotypes constructed from eight SNPs were robustly associated with asthma (p=0.00012). A small haplotype approach returned four alleles consisting of two (rs3136586/ rs3136598), three (rs12488654/rs3136586/rs3136598 and rs3136586/rs3136598/rs3136604), and four SNPs (rs12488654/ rs3136586/ rs3136598/ rs3136604) that were highly associated with asthma (p=0.00005, p=0.00008, p=0.00017 and p=0.00038). Combinations of SNPs in the TNFSF10 allele were strongly associated with asthma supporting the concept that TRAIL is important in the development of hallmark features of this disease.
