Amish and Mennonite communities have increased prevalence of recessively inherited disorders due to founder variants. A survey conducted in Wisconsin Plain communities revealed that Mennonites were more in favor of carrier screening for metabolic disorders and other surgical conditions, while less in favor of asymptomatic testing for neurologic and lethal disorders. The survey responses also indicated diversity in views towards genetic testing among Plain community members.
Amish and Mennonite (Plain) communities have increased prevalence of many recessively inherited disorders due to founder variants that can be identified using next-generation sequencing (NGS). We assessed newborn screening (NBS) utilization, prior genetic testing, and perceptions of genetic testing among Wisconsin Plain communities to guide implementation and utilization of a population-specific NGS gene panel testing. A mailed paper survey (N = 959) of demographics, NBS utilization, prior genetic testing, and preferences for categorical genetic disorder and defined clinical context testing was developed. Overall response rate was 39% (N = 378; 183 Amish, 193 Mennonite; 2 not Amish/Mennonite). Mennonites were more likely to respond in favor of carrier screening for metabolic disorders and other surgical conditions and less likely to respond in favor of asymptomatic testing for neurologic disorders and lethal disorders compared to Amish. Reported utilization of NBS was positively associated with stated interest in genetic testing for an asymptomatic child. Reported prior genetic testing was positively associated with stated interest in carrier screening and negatively associated with testing a symptomatic child. Although Plain community members share many common outward characteristics, our survey responses suggest diversity in their views of genetic testing and support laboratory methods that can be flexible to varied needs of individuals.
