Nearly 4% of patients harbored mutations in PDGFRA and MET each and 3% in ZFB1, COL3A1, and COL1A2. Next, we determined CNV in CRGs, and the results revealed the highest number of CNV gains in CTSK, S100A4, and CTHRC1 in patients with BLCA (Figure 1B). This evidence concerns the gene S100A4 and bladder transitional cell carcinoma.
