Mechanistic target of rapamycin (MTOR) is a gene that encodes a family of phosphatidylinositol kinase-related kinases. Activating MTOR mutations increase the kinase activity of MTOR, leading to hyperactivation of downstream pro-survival signaling pathways. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions are also observed. MTOR mutations are observed in cancers such as breast cancer, lung cancer, ovarian cancer, and skin cancer. 

MTOR is altered in 2.99% of all cancers with lung adenocarcinoma, colon adenocarcinoma, endometrial endometrioid adenocarcinoma, breast invasive ductal carcinoma, and bladder urothelial carcinoma having the greatest prevalence of alterations [3].

MTOR GENIE Cases - Top Diseases

The most common alterations in MTOR are MTOR Mutation (3.49%), MTOR Mutation (somatic) (3.49%), MTOR Loss (0.07%), MTOR E1799K (0.05%), and MTOR Amplification (0.04%) [3].
