Enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) is a gene that encodes the histone-lysine N-methyltransferase EZH2 protein. EZH2 is a member of the polycomb-group family. Members of this family suppress transcription of genes and are involved in embryonic development and cellular differentiation (Gene 2014Genetics Home Reference 2014). EZH2 mutations have been observed in myelodysplastic syndromes, lymphoma, colorectal cancer, and endometrial cancer. In MDS, these mutations often involve deletions or translocations which are believed to be associated with loss of function. Paradoxically, mutations in lymphomas and epithelial neoplasms are thought to involve gain of function.​

EZH2 is altered in 1.19% of all cancers with acute myeloid leukemia, lung adenocarcinoma, cutaneous melanoma, breast invasive ductal carcinoma, and colon adenocarcinoma having the greatest prevalence of alterations [3].

EZH2 GENIE Cases - Top Diseases

The most common alterations in EZH2 are EZH2 Mutation (1.45%), EZH2 c.1864-c.2195 Missense (0.47%), EZH2 Amplification (0.16%), EZH2 Nonsense (0.11%), and EZH2 Frameshift (0.11%) [3].
