The Publisher regrets that the article by Thomas et al. [1], which is part of this Epigenetics of Pediatric Brain Tumors: Clinical Implications collection, was published in an earlier issue 148(1):39–45.

We would like to express our thanks to the Guest Editors, Drs. Vidya Gopalakrishnan and Soumen Khatua, for their dedication and work assembling this collection of reviews and research for the Journal of Neuro-Oncology.
