H1: Individual with bilateral retinoblastoma, trilateral retinoblastoma, and a family history of retinoblastoma, or identification of a germline RB1 pathogenic variant. WebMutations in the RB1 gene are responsible for most cases of retinoblastoma. RB1 is a tumor suppressor gene, which means that it normally regulates cell growth and stops cells from dividing too rapidly or in an uncontrolled way. Most mutations in the RB1 gene prevent it from making any functional protein, so cells are unable to regulate cell division effectively.
