Objective:

To improve the diagnostic process for rare diseases through proactive exome reanalysis.

Approach:

• Proactive Exome Reanalysis: Proactive reanalysis involves continuous monitoring of new gene-disease relationships and automatic updates to clinical reports, contrasting with traditional one-time genomic testing.
• Study Evaluation: The study evaluated reanalysis rates in the context of patient race or ethnicity, highlighting disparities in access to reanalysis.

Key Findings:

• Initial positive exome results increased from 2,231 to 2,657 after reanalysis.
• Overall diagnostic yield rose from 21% to 25%, with 4% of originally negative cases becoming positive.
• Over 400 patients would have remained undiagnosed without reanalysis.

Interpretation:

Limitations:

• Exome reanalysis is time- and cost-intensive.
• Clinicians may struggle to keep up with new gene-disease associations.

Conclusion:
