| Definition: |
A diffuse large B-cell lymphoma that is categorized as EZB with high probability by the LymphGen algorithm. This is based on a combination of genetic features and EZB DLBCLs often, but do not always, have hot spot mutations in EZH2 and/or a BCL2 translocation. This class can be further subdivided into two sub-classes EZB-MYC+ and EZB-MYC- using the double hit gene expression signature (DHITsig). This subgroup also commonly has mutations due to aberrant somatic hypermutation affecting IRF8, which can be coding or non-coding. |
