The results showed that the eEF1A2 gene was highly expressed in breast invasive carcinoma, pancreatic adenocarcinoma, and pheochromocytoma and paraganglioma tissues, and was expressed at low levels in glioblastoma multiforme, brain lower grade glioma, and other tissues (Fig. 1). Here, EEF1A2 is linked to pheochromocytoma.
