T1805G, a functional TLR1 single nucleotide polymorphism (SNP), has been associated with susceptibility to pulmonary tuberculosis (PTB), but contradictory results among different populations have been reported.
In the present study, we investigated whether variants in the TLR-11805T/G (Ile602Ser), TLR-2 2258G/A (Arg753Gln), TLR-4 896A/G (Asp299Gly), TLR-4 1196C/T (Thr399Ile), TLR-6 745C/T (Ser249Pro), TIRAP 975C/T (Ser180Leu) genes and TLR-9 promoter region polymorphisms at positions -1237C/T and -1486C/T are associated with susceptibility or resistance to pulmonary tuberculosis (PTB).
The aim of this study was to investigate whether the functional genetic variations at position 1805 G/T in TLR1, 2258 A/G in TLR2, -857 C/T, and -863 A/C in tumor necrosis factor-α (TNF-α), as well as -819 C/T in interleukin-10 (IL-10) confer susceptibility to pulmonary tuberculosis (PTB).
