What causes MYH-associated polyposis?

Mutations in the MYH gene cause MYH-associated polyposis. Mutations in this gene prevent cells from correcting mistakes that are made when DNA is copied (DNA replication) in preparation for cell division. As these mistakes build up in a person's DNA, the likelihood of cell overgrowth increases, leading to colon polyps and the possibility of colon cancer.[1]
