description: An autosomal dominant condition caused by mutation(s) in the POLE and/or POLD1 genes, encoding DNA polymerase epsilon catalytic subunit A and DNA polymerase delta catalytic subunit, respectively. It is characterized by colorectal polyposis and a predisposition to colorectal cancer. Mutation(s) in POLE and/or POLD1 genes have been associated with an increased risk of endometrial cancer, breast and brain tumors, and multi-tumor phenotypes.
