Comparison of mutational frequencies between DLBCL, PMBCL, and cHL. (A) Comparison of mutation frequencies for putative PMBCL driver genes identified in Mottok et al³⁴ and compared with DLBCL (Reddy et al⁴² and Chapuy et al⁴³). EZH2(*) is the only gene with no significant difference in mutational frequency. (B) Mutational frequencies of PMBCL compared with cHL (Tiacci et al⁴⁴). Mutational frequencies are comparable for most genes. Statistically different mutation frequencies are identified by an asterisk.
