Elevated NUDT5 level has been reported as a poor prognostic marker of breast cancer (Tong et al., 2021), non-small cell lung cancer (Li et al., 2021), esophageal squamous cell carcinoma (Wang et al., 2020), and clear cell renal cell carcinoma (Wang et al., 2017). This evidence concerns the gene NUDT5 and clear cell renal carcinoma.
