Clinical Scorecard: Can Genomics Solve Rare Diseases?

At a Glance

Key Highlights

• Up to half of rare disease cases remain unsolved with traditional diagnostic approaches.
• Whole genome sequencing (WGS) is recommended for comprehensive genetic analysis.
• Sample quality and accurate phenotyping are critical for improving diagnostic yield.
• Multidisciplinary collaboration can reduce diagnostic delays and improve outcomes.
• Next-generation sequencing (NGS) has significantly advanced rare disease diagnostics.

Guideline-Based Recommendations

Diagnosis

• Consider rare genetic diseases when clinical presentations do not fit a single organ system or are unusually severe.

Management

• Utilize WGS as the most comprehensive test for suspected rare genetic diseases.

Monitoring & Follow-up

• Regular genomic review meetings and shared data platforms are recommended for ongoing case evaluation.

Risks

• Poor sample quality and incomplete clinical information can lead to missed variants and misclassification.

Patient & Prescribing Data

Individuals with suspected rare genetic conditions, especially those with negative or inconclusive test results.

Improving genomic analysis completeness and streamlining testing pathways can shorten the diagnostic odyssey.

Clinical Best Practices

• Document patient phenotypes using standardized terminology.
• Ensure high-quality sample collection and handling.
• Incorporate detailed clinical context in genetic variant interpretation.
• Foster multidisciplinary collaboration for timely diagnosis.
