Lysine (K)-specific methyltransferase 2D (KMT2D) is a gene that encodes a protein that functions as a histone methyltransferase that methylates the LYS-4 position of histone H3. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as intestine cancer, skin cancer, and stomach cancer.

KMT2D is altered in 8.52% of all cancers with lung adenocarcinoma, colon adenocarcinoma, bladder urothelial carcinoma, breast invasive ductal carcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in KMT2D are KMT2D Mutation (10.28%), KMT2D P2354Lfs*30 (0.14%), KMT2D P647Hfs*283 (0.09%), KMT2D Amplification (0.08%), and KMT2D G1235Vfs*95 (0.08%) [3].
