Abstract
Importantly, the DKFZ classifier raises the awareness that DNA methylation data may still be relevant in unmatched cases with low tumor content or low DNA quality. DNA methylation profiling improves routine diagnosis of paediatric central nervous system tumours: a prospective population-based study.
