In the KEGG pathway enrichment, the antigen processing and presentation (chx04612), systemic lupus erythematosus (chx05322), epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor resistance (chx01521), fatty acid elongation (chx00062), asthma (chx05310), inflammatory bowel disease (chx05321), leishmaniasis (chx05140), selenocompound metabolism (chx00450), transforming growth factor beta (TGF)-beta signaling pathway (chx04350), and FoxO signaling pathway (chx04068) were considered significantly enriched pathways (Table 1). The gene discussed is EGFR; the disease is systemic lupus erythematosus.
