In 2016, Jason T. Huse et al. reported a new type of epileptogenic tumor and named the entity as the polymorphous low-grade neuroepithelial tumor of the young (PLNTY) [3], a distinct epileptogenic neoplasm, characterized morphologically and molecularly by the presence of oligodendroglioma-like cellular component and genetic abnormalities of either B-Raf proto-oncogene (BRAF) or fibroblast growth factor receptors 2 and 3 (FGFR2, FGFR3). The gene discussed is FGFR2; the disease is oligodendroglioma.
