Somatic mutations in KMT2D and TET2 associated with worse prognosis in Epstein-Barr virus-associated T or natural killer-cell lymphoproliferative disorders.

ABSTRACT: Limited studies are available on the molecular pathogenesis of Epstein-Barr virus (EBV)-associated T or natural killer (NK) cell lymphoproliferative disorders (EBV+T/NK-LPD). In this retrospective study, we aim to elucidate the mutation profile of EBV+T/NK-LPD using capture-based targeted sequencing with a panel consisting of 64 lymphoma-related genes to identify driver genes associated with the development of EBV+T/NK-LPD. Targeted sequencing of 169 EBV+T/NK-LPD cases was performed using a panel of 64 lymphoma-related genes. Of the 169 EBV+T/NK-LPD cases, 123 had extra-nodal NK/T-cell lymphoma (ENKTL), 12 had aggressive NK-cell leukemia (ANKL) and 34 had EBV+ T-cell lymphoma of childhood (EBV+TL). The mutation profile revealed that all three subtypes of EBV+T/NK-LPDs had high mutation rat
