The IFN-α2 levels in ARN (271.5 ± 476.3 pg/ml, 77% detection) were respectively about 710-fold, 1000-fold, 800-fold, and 240-fold higher than those in the ERM (0.38 ± 0.98 pg/ml, 20%), IOL (0.26 ± 0.36 pg/ml, 46%), sarcoidosis (0.34 ± 1.29 pg/ml, 7%), and BE (1.13 ± 3.71 pg/ml, 19%) groups (Table 3). The gene discussed is IFNA2; the disease is sarcoidosis.
