The levels of IgG to the four antigens were all significantly higher in the TB-Non-DM and TB-DM groups than in the non-TB, with no statistical difference in the IgG levels between the TB-Non-DM and TB-DM groups (Figure 5B), demonstrating that concurrent DM in TB patients does not affect the detection of Mtb-specific Abs. The gene discussed is DDX41; the disease is diabetes mellitus.
