DDRGK1 and neoplasm: Of the 23 selected cancers, 14 showed high DDRGK1 expression in tumor tissue when compared to adjacent normal tissue, while only one tumor (pheochromocytoma and paraganglioma) showed lower expression of DDRGK1 compared to normal tissue (Figure 1A), suggesting that DDRGK1 may act as a cancer‐promoting gene in most tumors.
