BATF2 expression increased significantly with increasing disease: 1.4 log2 fold change, P value 0.0011 in incipient TB; 2.9 log2 fold change, P value 7.6 × 10−12 in subclinical TB; and 3.48 log2 fold change, P value 6.07 × 10−24 in clinical TB. This evidence concerns the gene BATF2 and tuberculosis.
