HOXD12 and oligodendroglioma: Although outcome data was not available for the Capper et al. cohort, oligodendrogliomas from this cohort were substantially enriched for central nervous system (CNS) WHO grade 3 tumors (p = 0.01, Fisher’s), as were their TCGA counterparts (p < 0.001, Fisher’s), indicating that HOXD12 gene body hypermethylation was likely prognostic in the Capper et al. cohort (Fig. 2g).
