These multilayer processes in SLE pathogenesis involve genes participating in apoptosis (TNFRSF21, IKBKG, IKBKB, BCL2L11, BAK1, TRAF3, IRF1, IRF3, IRF4, IRF5, IRF7, CCND2, PYCARD), regulation of ribonuclease activity (OAS1, OAS2, OAS3, OASL), complement activation (C1QB, C2, C3, C4B, CFB, ITGAM, ITGAX), and Fcγ receptor-mediated phagocytosis (FCGR2A, FCGR3A, FCGR3B, PTPRC, LYN, NCF1). The gene discussed is BCL2L11; the disease is systemic lupus erythematosus.
