#2128 Epigenetic Changes in DAXX and/or ATRX Negative Pancreatic Neuro-Endocrine Tumors

Introduction: The most commonly mutated genes in Pancreatic Neuroendocrine Tumors (PanNETs) are MEN1, DAXX and ATRX, which encode for proteins involved in epigenetic regulation. DAXX/ATRX mutated PanNETs are globally hypomethylated and behave clinically in a more aggressive way. Tumor pathways associated with these changes are still unclear. We hypothesize that DAXX/ATRX and MEN1 mutations mediate PanNET progression via epigenetic dysregulation.
