Retinoblastoma 1 (RB1) is a gene that encodes a protein that is a negative regulator of the cell cycle as well as a tumor suppressor. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as cancers of the fallopian tubes, cancers of the eye, and intestinal cancer.

RB1 is altered in 4.03% of all cancers with lung adenocarcinoma, breast invasive ductal carcinoma, small cell lung carcinoma, bladder urothelial carcinoma, and colon adenocarcinoma having the greatest prevalence of alterations [3].

RB1 GENIE Cases - Top Diseases

The most common alterations in RB1 are RB1 Mutation (4.71%), RB1 Loss (1.22%), RB1 Amplification (0.14%), RB1 R320* (0.08%), and RB1 Deletion (0.08%) [3].
