Although the remaining 7 genes (PKD1, FAM38A, WDR81, TMEM136, SLC36A1, SLC26A6, IGFLR1) are mutated in >10% of the colorectal cancer cell lines, literature searches did not reveal evidence of the functional role or therapeutic potential of these genes in colorectal cancer. This evidence concerns the gene WDR81 and colorectal cancer.
