Genes expression of POU2F1, AR, PDK2, GSTZ1, GZMM, ACADS, ENOPH1, HCK, NDST1, and VAV2 are significantly related to the OS of breast cancer patients younger than 35 years (Fig. 10a), and POU2F1, AR, PDK2, GRHPR, SCO2, ACADS, ENOPH1, PPP2R1A, NUDC, and VAV2 are significantly associated with the RFS (Fig. 10b). This evidence concerns the gene PDK2 and breast carcinoma.
