Variants in this GENE are reported as part of current diagnostic practice
Comment when marking as ready: Associated with phenotypes in OMIM and as a confirmed G2P associateions. At least 8 variants reported in Mismatch repair cancer syndrome 276300 and one in Muir-Torre syndrome 158320, however, these phenotypes do not include hamartomatous polyps characteristic of Peutz-Jeghers syndrome. No polyps are associated with colorectal cancer, hereditary nonpolyposis, type 2 609310Created: 11 Apr 2017, 3:01 p.m.
