Of interest, gene expression data from the colorectal adenocarcinoma (COADREAD) cohort25 shows that MTH1 gene expression is about 2-fold higher in CRC tumour tissue compared to normal colorectal tissue (data available from: http://firebrowse.org/viewGene.html?gene=nudt1). The gene discussed is NUDT1; the disease is colorectal adenocarcinoma.
