Except for GVINP1 and NCF1C, the expression of the other 5 prognosis-related DE pseudogenes (DDX12P, FER1L4, NSUN5P2, PLEKHA8P1 and RP9P) were higher in tumor tissues than in cutting edge normal tissues, which was totally consistent with the results of TCGA samples. This evidence concerns the gene DDX12P and neoplasm.
