Figure 9A, B revealed simple nucleotide variation of risk score groups in BLCA cases, suggesting that the 20 genes with the highest mutation rate in BLCA were TP53, TTN, KMT2D, MUC16, ARID1A, KDM6A, PIK3CA, SYNE1, RB1, FGFR3, HMCN1, KMT2C, RYR2, MACF1, EP300, FLG, FAT4, STAG2, ATM and OBSCN. Here, HMCN1 is linked to bladder transitional cell carcinoma.
