The aim of this study was to evaluate the association between previously reported SNPs IL2-330 T>G (rs2069762); IL4-590 C>T (rs2243250); IL6-174 G>C (rs1800795); IL10-592 A>C (rs1800872); IL10-1082 G>A (rs1800896); IL17A -692 C>T (rs8193036); IL17A -197 G>A (rs2275913); TNF -238 G>A (rs361525); TNF -308 G>A (rs1800629) and IFNG +874 T>A (rs2430561) and pulmonary TB (PTB) susceptibility.
The <i>TNF-α</i> -238 A allele appeared a protective effect against STB, whereas the <i>SP110</i> SNPs (rs722555 and rs1135791) and <i>TNF-α</i> -308G>A (rs1800629) showed no association with susceptibility to PTB and STB patients in southern China.
Based upon the functional role of the TNF-α [-308 G(low) → A(high) (rs1800629)] and IL-10 [-1082 A(low) → G(high) (rs1800870), -819 T(low) → C(high) (rs1800871) and -592 A(low) → C(high) (rs1800872)] single nucleotide polymorphisms (SNPs) on production levels, we genotyped 76 patients with pulmonary tuberculosis (TB) (pTB), 55 patients with extrapulmonary TB (epTB) and 95 healthy blood donors by polymerase chain reaction fragment length polymorphism (PCR-RFLP).
The aim of this study was to evaluate the association between previously reported SNPs IL2-330 T>G (rs2069762); IL4-590 C>T (rs2243250); IL6-174 G>C (rs1800795); IL10-592 A>C (rs1800872); IL10-1082 G>A (rs1800896); IL17A -692 C>T (rs8193036); IL17A -197 G>A (rs2275913); TNF -238 G>A (rs361525); TNF -308 G>A (rs1800629) and IFNG +874 T>A (rs2430561) and pulmonary TB (PTB) susceptibility.
