UW Undiagnosed Genetic Diseases Program
University of Wisconsin, Madison
Summary
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.
Description
An estimated 10,000 rare Mendelian genetic disorders affect, in aggregate, one in twelve individuals. Importantly, just over half of these diseases have a known genetic cause. This leaves thousands of disease genes waiting to be discovered and millions of affected individuals without a diagnosis. The investigators will address these critical issues in genomic medicine by using genome sequencing and other 'omics technologies to assess patients whose comprehensive clinical workups have failed to yield a diagnosis. The hypothesis is that, when carefully selected, these undiagnosed disease patient…

Inclusion Criteria: * The applicant has a condition that remains undiagnosed despite thorough evaluation by healthcare providers (including clinical genetic testing). * The applicant has at least one objective finding that is likely to have an identifiable genetic etiology. * The applicant likely has a currently undescribed/new genetic condition or a known genetic condition associated with a novel gene. * The applicant/legal guardian agrees to the collection, storage and recurrent sharing of coded information and biomaterials for research and diagnostic purposes both within and outside of the…
Interventions
- Diagnostic TestTrio Whole Genome Sequencing and Participant-Specific Research
The initial evaluation begins with short-read genome sequencing of DNA extracted from blood of affected individual(s) and participating family members (The most common approach will be trio whole genome sequencing, which involves the affected child + their parents). Additional evaluation may include: functional assessments, animal modeling, reverse phenotyping (may require an interim visit), epigenetic profiling, or clinical database matching through selective sharing of coded patient data with external collaborators (e.g., via Matchmaker Exchange and Phenome Central), long read genome sequencing, de novo genome assembly, RNA sequencing, and novel bioinformatics analyses
