ZNF671 and neoplasm: Examining methylation and expression in the same samples in TCGA-CESC revealed that hypermethylation of three of the genes, ZNF671, EDNRB, and FMN2 was associated with loss of gene expression, while TBXT and MOS, although hypermethylated in tumor, showed essentially non-detectable expression in tumors or normal tissues (Additional file 1: Fig. S3).
