What this research studies

At Washington University, teams of clinicians, geneticists, and laboratory scientists work together to review patient histories, perform genomic testing, and run specialized laboratory studies to look for rare or previously unrecognized conditions. The center accepts referrals from patients and clinicians and uses a formal clinical and genomic review process to prioritize testing and research follow-up. Results can include a genetic diagnosis, new management recommendations, or enrollment in further research that uses model systems to understand disease. The program builds on the Undiagnosed Diseases Network and aims to make these services available to a broader group of patients through coordinated care and follow-up.

Who could benefit from this research

Good fit: Best suited for children and adults who have persistent unexplained symptoms or suspected genetic conditions that remain undiagnosed after standard clinical testing.

Not a fit: People with common, well-characterized conditions that already have an established diagnosis or who cannot travel or participate in follow-up are unlikely to benefit.

Why it matters

Potential benefit: If successful, the center could provide diagnoses, inform medical care, and connect families to resources or research for rare unexplained conditions.

How similar studies have performed: The Undiagnosed Diseases Network has a track record of diagnosing rare conditions and this center extends that proven model.
