The 3D Genome: EZH2 Comes into the Fold

EZH2 is an oncogene in non-Hodgkin lymphoma. Understanding the underlying pathogenic mechanisms will be essential to improve treatments for patients with EZH2 mutant lymphomas. Recently Donaldson-Collier and colleagues ( Nat. Genet. 2019; published online January 28, https://doi.org/10.1038/s41588-018-0338-y) examined the effects of mutant EZH2 on the 3D architecture of the lymphoma genome, highlighting the potential relevance of chromatin folding dynamics
