Gene expression data from posterior fossa ependymomas

We have discovered two major molecular subgroups of PFA molecular group posterior fossa ependymomas by DNA methylation profiling. These are also distinguished by gene expression profiling using Affymetrix U133v2 arrays with correspondence to data generated by DNA methylation profiling.
