DNA Methylation-Based Classification of CNS Tumors: Comparable Performance Between Nanopore and EPIC Technologies

medRxiv Oncology | |

Background: DNA methylation profiling enables precise classification of pediatric central nervous system (CNS) tumors. Oxford Nanopore Technologies (ONT) offers same-day, single-sample methylation readouts, but its concordance with Illumina EPIC arrays in routine diagnostic tasks remains incompletely defined. Methods: We profiled 23 pediatric tumors (18 CNS, 5 non-CNS) by EPIC (v1/v2; FFPE w/o FF) and ONT (FF). CNS tumors from both…
