NCT02927158
Exome and Genome Analysis to Elucidate Genetic Etiologies and Population Characteristics in the Plain Community
This study is designed to utilize whole exome and whole genome sequencing techniques to identify underlying genetic causes for undiagnosed disorders in the Plain Communities, and to do population genetic studies looking at genetic drift and founder mutations in this unique population.

Rare and Undiagnosed Disease Research Biorepository
This research study is being done to find markers and identify causes of rare and undiagnosed diseases by analyzing patient's DNA (i.e., genetic material), RNA, plasma, urine, tissues, or other samples that could be informative of symptoms. Researchers are creating a biobank (library) of samples and information to learn more about treating rare and undiagnosed diseases.

UW Undiagnosed Genetic Diseases Program
The primary purpose of this study is to discover new disease genes for rare Mendelian disorders and its secondary purpose include diagnosing people with rare genetic disorders that have not been previously diagnosed through conventional clinical means, learning more about the pathobiology of genetic disorders, and developing novel diagnostic technologies and analytics. 500 participants with undiagnosed and suspected genetic disorders will be recruited.
