IDH1 and central nervous system cancer: To determine the correlation between CACNG3 expression and the occurrence and malignancy of gliomas, gene data of glioma patients were obtained from CGGA, TCGA, GSE 16,011, GSE 58,218 datasets and further analyzed with clinical parameters of gliomas (grades, IDH1 mutation status, 1p/19q codeletion status, and different molecular subtypes defined by TCGA network).
