Furthermore, six pathways related to the functions of the STAT family were found through KEGG analysis; pathways such as hsa05162: measles, hsa05161: hepatitis B, hsa00310: lysine degradation, hsa05340: primary immunodeficiency, hsa05145: toxoplasmosis, and hsa04664: Fc epsilon RI signaling pathway were involved in the tumorigenesis and pathogenesis of pan-cancer (Figure 12C). The gene discussed is SOAT1; the disease is inborn error of immunity.
