As for pneumonia, carriage ofthe rs5743708 A allele (the TLR2 gene) predisposes to severeCAP; the heterozygous genotype of rs8177374 (the TIRAPgene) in combination with the GG genotype of rs5743708 (theTLR2 gene) has a protective effect against it. Here, TLR2 is linked to susceptibility to pneumonia measurement.
