Moreover, PDGF‐D expression was significantly higher in gliomas expressing wild‐type isocitrate dehydrogenase (IDH) compared to the IDH‐mutant gliomas, and in 1p‐19q non‐codeletion gliomas versus 1p‐19q co‐deletion gliomas (Figure 1A). The gene discussed is PDGFD; the disease is central nervous system cancer.
