Focusing on NUDT1, 2, 5, and 16 we observed that although breast cancer is the patient dataset where the majority of datasets and the most statistically significant effect on outcome is observed, the expression of these NUDT enzymes is also predictive in other cancer types (Figure 2b, Supplementary Figure S1, full details are given in Supplementary Table S1). This evidence concerns the gene NUDT1 and cancer.
