However, for TLR4 rs4986791, a significant increased PTB risk was found in Africans, and for TLR9 rs352139 a significant increased PTB risk was found in Asians after subgroup analysis by ethnicity, although the enrolled studies were limited.
Human Toll-like receptor 4 polymorphisms TLR4 Asp299Gly and Thr399Ile influence susceptibility and severity of pulmonary tuberculosis in the Asian Indian population.
In the present study, we investigated whether variants in the TLR-1 1805T/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).
