The Hutterites are a religious branch of Anabaptists who live on communal farms in the prairie states and provinces of North America. A small number of founders, coupled with a tendency to intermarry, have caused a high frequency of the mutation for Bowen–Conradi syndrome among Hutterites. Bowen–Conradi syndrome results from defective ribosome biosynthesis, affecting the process of translation. Shown here are healthy Hutterite children.
