HMGA2 and nonpapillary renal cell carcinoma: A review of TCGA data showed HMGA2 to be overexpressed in ccRCC, but not in pRCC (Figure 7) and survival analysis showed significant poor outcome for the high HGMA2 expression group in both ccRCC and pRCC (log-rank test, p-value < 0.001 and 0.004, and adjusted p-value of < 0.001 and 0.026 for ccRCC and pRCC, respectively).
