Expression of DUT correlated with relapse-free survival (RFS) (P = 0.0051) (Supplementary Fig. 10A), however, this did not translate to a significant difference in OS (P = 0.07) (Supplementary Fig. 10B) across all breast cancer patients, similar to the previous data set analysed (Supplementary Fig. 9). The gene discussed is DUT; the disease is breast carcinoma.
