In the present study, a series of bioinformatic analysis identified 10 hub genes (IRF7, IFI35, IFIT3, ISG15, OAS1, MX2, OASL, IFI6, IFITM1, and IFIH1) between SLE and HC samples based on the gene expression profiles obtained from the GSE49454 and GSE20864 datasets. The gene discussed is IRF7; the disease is systemic lupus erythematosus.
