GRPEL2 and neoplasm: Upon subdividing the tumor groups in the TCGA dataset (GBMLGG) into Grade-II (n = 225), Grade-III (n = 272), and Grade-IV (n = 165), based on the WHO’s classification, we demonstrated that GRPEL2 mRNA expression significantly differs among groups, and that more malignant (higher WHO grade) tumors had a higher expression level.
