IFN-γ level was significantly increased in all IIM subgroups (ASyS (1.05 [0.47-2.46] pg/ml), DM (0.90 [0.55-2.09] pg/ml), IMNM (0.96 [0.42-1.29] pg/ml) and IBM (0.93 [0.42-2.09] pg/ml)) compared with HD (0.46 [0.29-0.59] pg/ml), p<0.05) (Figure 1C). The gene discussed is IFNG; the disease is dermatomyositis.
