What this research studies

From a patient's view, the team will create a national data hub and support system so diagnostic centers can share medical records, genetic data, and test results securely. Harvard will run three cores—administrative, data management, and clinical research support—to connect experts in bioinformatics, novel tests, and clinical care. The goal is to scale the successful Undiagnosed Diseases Network so more people with mysterious or rare symptoms receive coordinated review and advanced testing. If you apply, your information and samples could be used to help find a diagnosis and to learn about new causes of disease.

Who could benefit from this research

Good fit: Ideal candidates are people with unexplained, rare, or hard-to-diagnose medical conditions who can share their medical records and may provide samples or follow-up information.

Not a fit: Patients with common, well-understood conditions or those unwilling to share data or participate in follow-up are unlikely to benefit from this program.

Why it matters

Potential benefit: This could shorten diagnostic odysseys and give patients access to advanced testing and specialist teams.

How similar studies have performed: The original Undiagnosed Diseases Network has a track record of diagnosing many patients, and this project expands that successful model.
