Given that BATF2 can discriminate between active TB and healthy cases, and that an additional 4 genes can discriminate active TB from a wide range of other infectious diseases presenting with fever, we sought to combine the expression levels of BATF2 with CD177, HP, IGJ, and CLC in a single SVM model to discriminate active TB from postrecovery cases in the AdjuVIT cohort, and from other diseases in the Fever cohort. The gene discussed is CLC; the disease is tuberculosis.
