High expression of CDCA3 was correlated with poorer OS and DFS in adrenocortical carcinoma (ACC), KIRC, KIRP, brain lower grade glioma (LGG), LIHC, LUAD, mesothelioma (MESO), and sarcoma (SARC); poorer DFS in kidney chromophobe (KICH), pheochromocytoma and paraganglioma (PCGP), PRAD, uterine corpus endometrial carcinoma (UCEC), and uveal melanoma (UVM); and poorer OS in pancreatic adenocarcinoma (PAAD) and skin cutaneous melanoma (SKCM). This evidence concerns the gene CDCA3 and paraganglioma.
