Significant correlations were observed between SUMF1 overexpression and various factors including IDH status (wild-type or mutant), 1p/19q codeletion, age (≤60 or >60), histological type (astrocytoma, oligoastrocytoma, oligodendroglioma, or glioblastoma), OS event (alive or deceased), DSS event (alive or deceased), and PFI event (alive or deceased). This evidence concerns the gene SUMF1 and oligodendroglioma.
