# EZH2
2
+## Overview
3
+EZH2 encodes a histone methyltransferase that is a component of the polycomb repressive complex 2 (PRC2). This gene is recurrently mutated in both FL and DLBCL and has a common mutation hot spot (Y646) that affects the SET domain.<sup>1</sup> Mutations of this residue and some of the less common hotspots lead to enhanced methylation by PRC2.<sup>2,3</sup> Pharmacologic inhibitors of this activity such as tazemetostat have shown benefit in FL.<sup>3</sup>
