To assess the association between TMIGD2 gene expression and clinical features of glioma patients, we analyzed transcriptomic data from the TCGA (248 grade 2, 264 grade 3, and 153 grade 4 patients) and the CGGA cohorts (188 grade 2, 255 grade 3, and 249 grade 4 patients) (Figure 1). The gene discussed is TMIGD2; the disease is central nervous system cancer.
