COL7A1 and adrenal cortex carcinoma: COL7A1 suggested poor prognosis in a variety of TCGA tumors: kidney cancer (KIRC: HR = 1.36; KIRP: HR = 1.23; KICH: HR = 1.45), mesothelioma (MESO: HR = 1.36), adrenocortical carcinoma (ACC: HR = 1.37), lung adenocarcinoma (LUAD: HR = 1.11), pancreatic adenocarcinoma (PAAD: HR = 1.17), and cholangiocarcinoma (CHOL: HR = 1.40) (Supplementary Figure S2).
