Interestingly, GRAMD1C is co-expressed with several mitochondrial genes in ccRCC samples, including AUH, MICU2, and SIRT5, which all moderately correlated with GRAMD1C with Pearson’s correlations values of above 0.45 (Supplementary Fig. 6c). The gene discussed is MICU2; the disease is nonpapillary renal cell carcinoma.
