KLF9 and renal cell carcinoma: For example, BAP1 (P = 4.4×10−5), JMJD6 (P = 1.6×10−6) and multiple members of Kruppel-like factor family like KLF1 (P = 9.4×10−5) and KLF9 (P = 1.7×10−9) were found to have a stronger association with ccRCC, although, as expected, their association with RCC was suggestive as well (P < 0.05).
