Although studies associating BRD4 and CIITA genes with PRCC patient survival have not yet been reported, previous studies on CCRCC patients have reported that overexpression of BRD4 (p = 0.0003) and CIITA (p = 0.037) genes is associated with lower survival rates [28,29]. The gene discussed is CIITA; the disease is nonpapillary renal cell carcinoma.
