CDH23 and neoplasm: To verify how methylation can control the Cdh23‐expression, we compared the methylation sites in various regions of Cdh23 gene (Promoter, CpG island, 5′UTR, gene body, 3′‐UTR; Fig. S4a) for normal (n = 32) and LUAD tumor (n = 463) patients as deposited in MethHC database in TCGA.
