All four of these genes were identified in the 44 gene expression signature for TB/OD, and although GBP6 is induced by the interferon (IFN) cytokine family, its levels were significantly higher in active TB cases when compared to confirmed viral and bacterial infections the GSE73464 (32) and GSE39941 (33) datasets (Supplementary Figure 2). The gene discussed is IFNA1; the disease is tuberculosis.
