text: TCF7L2 plays a role in colorectal cancer. A frameshift mutation of TCF7L2 provided evidence that TCF7L2 is implicated in colorectal cancer. The silencing of TCF7L2 in KM12 colorectal cancer cells provided evidence that TCF7L2 played a role in proliferation and metastasis of cancer cells in colorectal cancer.
  Variants of the gene are most likely involved in many other cancer types. TCF7L2 is indirectly involved in prostate cancer through its role in activating the PI3K/Akt pathway, a pathway involved in prostate cancer.
