| 2 | 2 | ## Overview |
| 3 | -CD79B mutations significantly contribute to the pathogenesis of DLBCL by enhancing BCR signaling and promoting tumor survival. These mutations, especially when co-occurring with MYD88 mutations, define a unique molecular subtype.<sup>1</sup> This has clinical and therapeutic implications as it may contribute sensitivity to BTK inhibitors. In an inducible mouse model of MYD88-driven DLBCL, CD79B mutations did not accelerate lymphomagenesis but demonstrated an increased sensitivity to pharmacological BTK inhibition.<sup>2</sup> In a retrospective analysis, younger patients with MCD DLBCL that were treated with ibrutinib had significantly better outcomes.<sup>3</sup> |
