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. This evidence concerns the gene CLC and infectious disease.
