We constructed a prognostic model based on Necroptosis subtype-related prognosis DEGS by lasso algorithm and multivariate COX analysis, which consists of 6 predictors (CERCAM POLR1H, KCNJ15, GSDMB, EHBP1, TRIM38), among which CERCAM is closely related to bladder cancer. The gene discussed is POLR1H; the disease is urinary bladder carcinoma.
