When moments matter: Finding answers with rapid exome sequencing

Area of Science:

• Genomics
• Clinical Diagnostics
• Molecular Biology

Background:

• Rapid molecular diagnosis is crucial in critical care for timely treatment, prognosis, and patient counseling.
• Clinical rapid exome sequencing (cRES) is an emerging tool for complex cases.
• Assessing diagnostic rates and quality of life improvements is essential.

Purpose of the Study:

• To evaluate the diagnostic yield of rapid exome sequencing in a critical care setting.
• To assess the impact of rapid exome sequencing on patient quality of life.
• To determine the turnaround time for rapid exome sequencing reports.

Main Methods:

• Retrospective review of clinical histories and results for 41 patients.
• Analysis of diagnostic rates and relevant findings from rapid exome sequencing.
• Calculation of average time to verbal and written reports.

Main Results:

• A definitive diagnosis was achieved in 31.7% (13/41) of patients.
• Other relevant findings were identified in 41.5% (17/41) of patients.
• Average turnaround time was 7 days for verbal reports and 11 days for written reports.

Conclusions:

• Rapid family-based diagnostic exome sequencing is effective in critical care.
• The study demonstrates the utility of cRES in improving patient care outcomes.
• Timely molecular diagnosis through exome sequencing aids clinical decision-making.
