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 9.96% 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].

KMT2D GENIE Cases - Top Diseases

The most common alterations in KMT2D are KMT2D Mutation (8.24%), KMT2D Amplification (0.10%), KMT2D Loss (0.07%), KMT2D Fusion (0.20%), and KMT2D-GPS2 Fusion (0.20%) [3].
