In an extensive review of RNA-Seq and gene chip data sourced from TNMPlot, KIF20A expression was substantially elevated in several cancer types relative to normal tissue, with RNA-Seq data demonstrating the most significant increases in cholangiocarcinoma, showing a mean fold change of 67.07 and a median of 42.67, and liver hepatocellular carcinoma, with a mean fold change of 20.78 and a median of 16.50. This evidence concerns the gene KIF20A and cholangiocarcinoma.
