DOT1-like histone H3K79 methyltransferase (DOT1L) is a gene that encodes a protein that functions as a histone meythltransferase that methylates lysine-79 of histone H3. Missense mutations, nonsense mutations, silent mutations, frameshift insertions, and in-frame deletions are observed in cancers such as intestinal cancer, stomach cancer, and cancers of the urinary tract.

DOT1L is altered in 2.46% of all cancers with lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, breast invasive ductal carcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in DOT1L are DOT1L Mutation (2.02%), DOT1L Loss (0.23%), DOT1L Amplification (0.06%), DOT1L R853C (0.02%), and DOT1L T735M (0.02%) [3].
