Genetic disease amongst the Plain community

Area of Science:

• Genetics
• Population Health
• Medical Research

Background:

• Genetically isolated populations, such as the Amish and Mennonite (Plain) communities, have historically contributed to understanding genetic diseases.
• Studying these groups offers unique insights into disease mechanisms and potential treatments applicable to broader populations.

Purpose of the Study:

• To review recent genetic research conducted within the Amish and Mennonite communities.
• To highlight advancements in genetic disease discovery, gene identification, and therapeutic strategies.

Main Methods:

• Review of recent genetic studies focusing on the Amish and Mennonite populations.
• Analysis of research encompassing gene discovery, phenotype expansion, and therapeutic targets (e.g., AAV9-mediated gene therapy).
• Inclusion of genome-wide association studies (GWAS) on complex traits and studies on community attitudes towards genetic testing and telemedicine.

Main Results:

• Identification of novel causative and candidate genes for genetic disorders.
• Expansion of phenotypic descriptions for known genetic diseases.
• Exploration of AAV9-mediated gene therapy as a treatment target.
• Genome-wide association studies (GWAS) investigating complex traits like dementia and cardiometabolic disease.
• Studies on the Plain community's perspectives on genetic testing and telemedicine.
• Development of management strategies for Amish-specific variants, including propionic acidemia and familial hypercholesterolemia.

Conclusions:

• Continued value of studying isolated populations for accelerating genetic disease discovery and treatment.
• Need for population-specific polygenic risk scores to prevent medical genetics disparities.
• Importance of developing clinical management guidelines for genetic variants prevalent in the rapidly growing Plain population.
