Previously, two single-nucleotide polymorphisms of innate-immunity genes – rs5743708 (Arg753Gln) of the TLR2 geneand rs8177374 (Ser180Leu) of the TIRAP gene – have been shown to be associated with both pneumonia and tuberculosis in humans, but the data are contradictory among different ethnic groups. This evidence concerns the gene TLR2 and susceptibility to pneumonia measurement.
