UMOD and nonpapillary renal cell carcinoma: Differentially methylated m6A sites in NADH dehydrogenase (ubiquinone) 1 alpha subcomplex, 4-like 2 (NDUFA4L2), Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase 2 (PLOD2), NXPH family member 4 (NXPH4), Krüppel-like factor 11 (KLF11), Natriuretic peptide receptor 3 (NPR3), Uromodulin (UMOD), and ankyrin 3(ANK3) indicate that these genes are linked to ccRCC.
