Though the exact prevalence of Lynch syndrome-causing mutations in the general population remain unknown, recent studies estimate the prevalence to be 1 in 279 individuals, or 0.35%. Certain populations are known to have a higher prevalence of founder mutations, including, but not limited to, French Canadians, Icelanders, African Americans, and Ashkenazi Jews. Lynch syndrome-causing mutations are found in approximately 3% of all diagnosed<unk>  cancers, and 1.8% of all diagnosed endometrial cancers. The average age of diagnosis of cancer in patients with this syndrome is 44 years old, as compared to 64 years old in people without the syndrome.
