Thirty-five selected tag SNPs in IL12B, IL12RB1, IL18R1, IL27, IFNGR1, IFNGR2, STAT1, TNF, LTA, IL10, and CCL2 genes were genotyped in 1,032 TB cases and 1,008 controls of Chinese Han origin, with all genotype distributions in the control group consistent with those expected from the HWE (P values >0.01). Here, TNF is linked to tuberculosis.
