Supplementary figure 6, Supplementary Material online, shows the detailed genetic map of these genes. We also found that the proteins encoded by MAK16, FUT10, and TTI2 are expressed in several cancer types, including urothelial cancer. Indeed, these proteins showed high/medium expression in 25%, 80%, and 100% of urothelial cancer patients tested, respectively (supplementary fig. 7, Supplementary Material online); data obtained from the Human Protein Atlas (Uhlén et al. 2015). This evidence concerns the gene TTI2 and cancer.
