We extracted 15 genes (ALOX15B, CEL, UBE2L6, ABCD1, HSPH1, PTGDS, NDUFAB1, ALDH3A1, ADH6, ACSL1, PSME1, NUDT19, ACSL5, RDH16, and IL4I1) with prognostic impact on breast cancer patients, and these genes have been studied in the relevant literature. This evidence concerns the gene IL4I1 and breast carcinoma.
