The expression of GNG7 in CCRCC was further explored based on TCGA database.Consistent with the findings of previous studies, GNG7 expression was significantly correlated between tumor samples and normal samples, including MRNA expression in unpaired and paired samples and protein expression in unpaired samples (Supplementary Figure S1A-C). The gene discussed is GNG7; the disease is nonpapillary renal cell carcinoma.
