We performed an unsupervised consensus clustering of the samples based on the similarity of the transcriptomic profile of the (13) clock genes, members of the Kyoto Encyclopedia Genes and Genomes (KEGG) circadian rhythm pathway [42], which allowed us to appraise the patterns in the clock gene transcriptomic profiles and their association with known glioma prognostic markers, including age, IDH status, and sex. The gene discussed is CLOCK; the disease is central nervous system cancer.
