Ras-like without CAAX 1 (RIT1) is a gene that encodes a protein that belongs to the Ras-related GTPases subfamily. The protein regulates p38 MAPK-dependent signaling cascades that are related to cellular stress. Missense mutations, nonsense mutations, silent mutations, and in-frame deletions are observed in cancers such as intestinal cancer, lung cancer, and salivary gland cancer.

RIT1 is altered in 1.01% of all cancers with lung adenocarcinoma, breast invasive ductal carcinoma, endometrial endometrioid adenocarcinoma, colon adenocarcinoma, and bladder urothelial carcinoma having the greatest prevalence of alterations [3].

The most common alterations in RIT1 are RIT1 Amplification (0.52%), RIT1 Mutation (0.34%), RIT1 M90I (0.04%), RIT1 M90V (0.01%), and RIT1 A77T (0.01%) [3].
