WebInactivation of the RB1 gene is usually induced by mutations affecting and coding region. Silencing by methylation of who RB1 promoter has been watch in retinoblastoma tumors since a second mutation (M2) and is classified as somatics epimutation. WebInactivation of RB1, and CDKN2A are very common, and p53 inactivation occurs in as many as 76% of MIBCs (Cancer Genome Atlas Research Network, 2014). Similarly loss of the tumor suppressor gene RB1 is common in MIBC and leads to amplification and overexpression of the oncogene E2F3 (Knowles and Hurst, 2015).
