Among these, 17 were identified as differentially expressed SLE associated genes (DEAGs), including AGPAT4, BCAR3, CD4, DDR2, F11R, FARP1, FCGR2A, FRMPD1, HECW2, ITGA11, MCTP2, NUDCD3, PPIF, RASA3, SUMF1, TMEM181, and USP8 (Table S6). This evidence concerns the gene DDR2 and systemic lupus erythematosus.
