Abstract

The genetic subtypes of Burkitt Lymphoma (BL) have been defined, whereas the role of epigenetics remains to be comprehensively characterized. We searched genomic DNA from 218 patients across four continents, for recurrent DNA methylation patterns and their associations with clinical and molecular features. We identified DNA methylation patterns that were not fully explained by EBV status or mutation status, leading to two epitypes, described here as HypoBL and HyperBL. Each is characterized by distinct genomic and clinical features including global methylation, mutation burden, aberrant somatic hypermutation, and survival outcomes. Methylation, gene expression and mutational differences between the epitypes support a model in which each arises from a distinct cell-of-origin. These results, pending validation in external cohorts, point to a refined risk assessment for BL patients who may experience inferior outcomes.
