Using the online tool KM plotter [11] and making the analyses for those ten genes we observed that, CD300A, CD6, DAPP1, TLR6, CSF2RA and BTN2A2 were associated with improved RFS only, while HLA-C, HLA-F, HLA-G and TIGIT were associated with both improved RFS and OS in basal breast cancer patients (Fig 1B). Here, BTN2A2 is linked to breast cancer.
