MYH Associated Polyposis with a p.Tyr165Cys Mutation in a Moroccan Patient

Recessively inherited mutations in the base excision repair gene MYH are related to MYH-associated polyposis (MAP). We report a Moroccan patient who carried the mutation p.Tyr165Cys. Genetic testing for MYH mutations should have important implications for accurate genetic counseling, and cancer surveillance for patients with colorectal cancers and their family members in Morocco.
