A total of 8 immune genes (ITGA7, RBM14, DENND4B, LQK1, ZNF709, COL7A1, SP1, NCBP2) were identified as independent prognostic factors of pancreatic cancer, which were used to construct a clinical predictive model (as shown in Table 1). The gene discussed is ZNF709; the disease is familial pancreatic carcinoma.
