However, some other genetic disorders confer an increased risk of colorectal cancer, such as Li–Fraumeni syndrome (TP53 gene), MUTYH-associated polyposis (MUTYH gene), Peutz–Jeghers syndrome (STK11 gene), Cowden syndrome (PTEN gene), and juvenile polyposis syndrome (BMPR1A and SMAD4 genes). This evidence concerns the gene STK11 and hereditary disease.
