The cuproptosis-related lncRNAs in this study were obtained by co-expression of cuproptosis-related genes and lncRNAs, and a predictive model for ccRCC prognosis was constructed using five cuproptosis-related lncRNAs (FOXD2-AS1, SUCLG2-AS1, LINC00271, NUP153-AS1, and LINC02154). This evidence concerns the gene SUCLG2 and nonpapillary renal cell carcinoma.
