IL7R and tuberculosis: The expression of FCGR1A and IL7R were the only TB-associated markers that were consistently differentially expressed between TB patients and control groups in our study compared to the previous study in the context of Ethiopia and this may be attributable to the selection criteria for the control groups [30] which consisted of household contacts in Mihret et al. and daily laborers in our study, or may reflects huge genetic heterogeneity amongst the Ethiopian population.
