Analysis of the qRT-PCR data showed that S100P (p = 0.004), GLDC (p = 0.016) and HBD (p = 0.027) significantly discriminated TB from LTBI while PIGC (p = 0.007), SNX17 (p = 0.019), TAS2R46 (p = 0.017) and HBD (p = 0.007) significantly discriminated TB cases from HC. This evidence concerns the gene GLDC and tuberculosis.
