DNA methylation profiles for the SIOP Ependymoma I Study. DNA methylation profiles for the SIOP Ependymoma I Study

DNA methylation profiles were generated for cases in the SIOP ependymoma I study. Samples were analysed using the Illumina 450k BeadChip and processed using the Heidelberg classifier (v11.2b). The aim of the biological studies aspect of the trial was to perform a retrospective analysis of the methylation profiles of the participants in the trial. Overall design: 35 samples were analysed and found to be consistent with ependymoma (74 participants in the study but the remainder did not have tissue available for analysis).
