The analysis results showed that compared with adjacent normal tissues, 2 sites of SNHG3 DNA, 3 sites of SNHG15 DNA, 6 sites of SNHG12 DNA and 8 sites of SNHG17 DNA were significantly hypomethylated in ccRCC (Figure 5E–5H). This evidence concerns the gene SNHG17 and nonpapillary renal cell carcinoma.
