In particular, the molecular marker of CD34 expression or BRAFV600E mutation could also be observed in other low-grade tumors with epilepsy, especially in PXA, but less observed in PA, angiocentric glioma (AG), papillary glioneuronal tumor (PGNT) or polymorphous low-grade neuroepithelial tumor of the young (PLNTY)1–3,5–7. This evidence concerns the gene CD34 and papillary glioneuronal tumor.
