EWSR1 and ganglioglioma: analyzed methylation profiles in 7 of 40 BRAFV600-negative gangliogliomas and unexpectedly identified EWSR1::PATZ1 fusions during molecular evaluation of a putative papillary ganglioglioma for SLC44A1 (solute carrier family 44, member 1)::PRKCA (protein kinase C alpha) fusions.
