Out of the 48 genes which were significantly differentially expressed between TB cases and TST+ subjects in this HIV-negative cohort, only 7 genes (CD4, PTPRCv1, TLR3, TNFRSF1A, NLRP12, BLR1 and FCGR1A) were significantly different between HIV-positive TB cases and TST+ individuals in our previous study in the same location [24]. This evidence concerns the gene NLRP12 and tuberculosis.
