Posterior fossa type A (PFA) ependymoma is an unusual infantile brain tumour with few known somatic mutations, thought to be driven by epigenetic mechanisms1. PFA ependymoma has a markedly higher incidence and worse prognosis in male children than in female children2. The mechanisms that underlie these sex differences are at present unknown. Here we show that the cellular hierarchy of PFA ependymoma is less differentiated in male individuals than it is in female individuals. In the normal developing mouse hindbrain, male gliogenic progenitors are less differentiated than matched female sibling controls. To further parse the effects …
