Among MSS tumors only, one mRNA (ANAPC13) was significantly differentially expressed that was not associated with overall colorectal cancer, and three mRNAs (MCM5, MDM2, and WEE1) were unique to MSI tumors when considering only genes with a FC > 1.50 or < 0.67 and correcting for multiple comparisons. This evidence concerns the gene WEE1 and colorectal cancer.
