Thirty-one host genes including CD19, NCAM1, CD3E, CD4, CD8A, CCR7, IL7R, PTPRCv1, GATA3, IL5, IL13, CCL4, CTLA4, GNLY, GZMB, PRF1, CASP8, BCL2, TNFRSF1A, CD163, CCL2, CCL5, TLR9, NLRP1, NLRP2, NLRP12, AREG, RAB13, RAB33A, SEC14L1 and BLR1 had significantly lower expression in TB patients compared to TST- subjects; while 8 genes including AIRE, TNF, MRC2, NOD2, TLR5, FCGR1A, RAB24 and TAGAP were significantly more highly expressed in TB cases compared to TST- subjects. The gene discussed is FCGR1A; the disease is tuberculosis.
