To achieve this, we employed gene lists associated with Posterior fossa subgroup A ependymoma (PFA-EPN), Supratentorial ependymoma (ST-EPN), Shh-Medulloblastoma (SHH-MB), and Group 3 and 4 Medulloblastomas (G3-MB and G4-MB) (Figure 5A) [23,26]. This evidence concerns the gene SHH and medulloblastoma.
