This study is the first to comprehensively analyze and reveal TGIF1, as a new oncogene, is closely related to the malignancy‐related phenotype of glioma, and that TGIF1 could be an independent risk factor for poor prognosis of glioma, which is expected to become a new target for individualized treatment of glioma patients. Here, TGIF1 is linked to glioma.
