CDC73 and nonpapillary renal cell carcinoma: Among candidate genes positively correlated with MATR3, six genes were found to be significantly associated with better survival when overexpressed in ccRCC, including TBC1D15, KHDRBS1, STAG2, G3BP1, CDC73, and CHM (p < 0.05; Figure S3A–F), while VPS26A, RAB6A, STX12, and PUM2 tended to be related to better OS (p < 0.2; Figure S3G–J).
