BCOR and central nervous system neoplasm: Given that CNS tumors with previously reported BCOR alterations, such as BCOR ex15 ITD, EP300-BCOR fusions, and loss-of-function mutations predominantly arise in pediatric or young adult patients, expanding analysis to larger cohorts enriched in pediatric patients would be warranted and may increase the chances of detecting further events involving CREBBP and/or BCOR.
