It was also reported that hypermethylation in promoter region of several tumor suppression genes, such as PCDH17, NEFH, GREM1, GATA5, LAD1, NEFH, NEURL and SFRP1, was associated with poor survival of ccRCC patients [46–48]. The gene discussed is NEURL1; the disease is nonpapillary renal cell carcinoma.
