A gene-based prognostic model was established to evaluate the survival risk for each patient as follows: Risk score = 0.00710 × expression of PGK1 + 0.00187 × expression of SDC1 + 0.05107 × expression of NUP43 + 0.05599 × expression of NT5E + 0.00587 × expression of IL13RA1 + 0.05692 × expression of GCLC + 0.01385 × expression of CACNA1H + (-0.00535) × expression of P4HA1 + 0.011698 × expression of TSTA3 + 0.026129 × expression of MXI1 + 0.00305 × expression of STC1. We then analyzed the mutational status of these 11 selected genes in TCGA BC samples in the cBioPortal database. This evidence concerns the gene GFUS and breast cancer.
