developed a risk score model based on DNA methylation‐expressed (DME) gene profiles from 259 glioma samples (WHO grades I–III, TCGA database) and identified six DME genes (EMP3, DDIT4L, MEOX2, OCIAD2, TGFB2, TNFRSF12A) associated with survival outcomes [51]. The gene discussed is OCIAD2; the disease is central nervous system cancer.
