The EP300:BCOR fusion extends the genetic alteration spectrum defining the new tumoral entity of “CNS tumors with BCOR internal tandem duplication”
Résumé
High-grade neuroepithelial tumors with the BCOR alteration (HGNET-BCOR) were isolated by a distinct methylation profile from a series of central nervous system (CNS) primitive neuroectodermal tumors (PNET). These tumors are mainly (94%, 45/48 with available molecular data) characterized by a recurrent internal tandem duplication (ITD) of the BCOR (BCL6 Corepressor) gene. In rare cases, HGNET-BCOR presented a deletion of BCOR (3%, 1/48) or a mutation of the BCOR gene (3%,1/48). In one case, molecular analyses failed to reveal any alteration of BCOR.
