Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals of Amish or Mennonite descent who have undiagnosed genetic disorders.
✕Probably not a fit
Patients who are not of Amish or Mennonite descent will not benefit from this study.

What this trial studies
This study aims to use whole exome and genome sequencing to uncover genetic causes of undiagnosed disorders within the Old Order Amish and Mennonite populations. By identifying genetic defects in individuals with clinical features suggestive of Mendelian disorders, the research seeks to establish a Translational Medicine Program that enhances diagnostic strategies and reduces costs for these communities. The study will also explore population genetics to understand genetic drift and founder mutations, ultimately improving clinical interventions and health outcomes for participants.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnosis and treatment options for individuals with undiagnosed genetic disorders in the Plain Communities.
How similar studies have gone: Other studies utilizing genetic sequencing in similar populations have shown promise, indicating potential for success in this approach.
