Moreover, this gene set was enriched among gene sets from other cancers: EGFR-KRAS-ALK–negative lung adenocarcinoma in never-smokers (CFTR, CTNNB1, EGFR, ERBB4, MXRA5, TGFBR2) (42), bladder cancer (EGFR, ERBB4, FLCN, PIK3R1, TSC2) (43), and metastatic renal cell carcinoma (DEPDC5, EGFR, FLCN, PIK3R1, TSC2) (44), suggesting they could have a broader role in cancer. The gene discussed is PIK3R1; the disease is urinary bladder carcinoma.
