KDM6A and urinary bladder cancer: Beyond KDM6A, other genes involved in epigenetic regulation, including KMT2C (Lysine N-methyltransferase 2C), KMT2D (Lysine N-methyltransferase 2D), and ARID1A (AT-rich interactive domain-containing protein 1A), also display aberrant expression patterns in bladder cancer.
