We explored the potential relationship between CBX7 and IDH mutation in glioblastoma in the TCGA and CGGA datasets, finding that CBX7 expression (p < 0.05) was positively correlated with IDH mutation, suggesting that CBX7 is a potential biomarker for predicting glioblastoma survival and IDH classification (Fig. 1G). Here, CBX7 is linked to glioblastoma.
