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.

NCT04703179

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.

Longitudinal Study of Ultra-rare Inherited Metabolic and Degenerative Neurological Diseases.

General aim of the study is the improvement of the clinical knowledge of ultra-rare inherited metabolic and degenerative neurological diseases (prevalence less than 5:100,000) in adulthood through the systematic longitudinal collection of clinical, laboratory and instrumental data.
