Some Severe Genetic Disorders
Although the Amish are less likely to develop cancer due to their “clean” living, they don’t get off scot-free. The Amish communities are considered “genetically closed,” which means their populations have higher incidences of genetic disorders. Some genetic disorders are so rare that doctors have never seen them before outside of the Amish community.
These genetic problems are linked to what’s known as the “founder effect” since more than 150,000 Amish living in the U.S. can trace their roots back to the same 100 or so German-Swiss settlers.
