MEF2B and cancer: This report showed that evaluation of the mutation status of seven cancer-associated genes (i.e. EZH2, ARID1A, MEF2B, EP300, FOXO1, CREBBP, and CARD11) with deep sequencing improved prognostication of follicular lymphoma patients receiving first-line immunochemotherapy when integrated into FILIP1 and ECOG prognostic indexes, which in turn outperformed prognostications performed with FILIPI alone or FILIPI combined with ECOG performance status.
