TLR7 and TLR8 were only studied in two studies and TLR1, TLR3, and TLR5 in one study: For TLR7, associations with asthma phenotypes for rs179008 separately, and rs179008, rs5743781, rs864058 haplotypes were observed in one study, however, rs179008 showed no association in another study (Table 3) [27,28]. Here, TLR8 is linked to asthma.
