Molecular Autopsy Study

Recruiting

• Conditions: Sudden Unexplained Death

• Registration Number: NCT02168088
• Lead Sponsor: Scripps Translational Science Institute

Brief Summary

This study seeks to incorporate genetic testing into the postmortem examination of cases of sudden unexplained death.

Detailed Description

This study seeks to incorporate genetic testing into the postmortem examination of cases of sudden unexplained death, initially in San Diego County with plans to expand nationally and internationally as funding allows. Genetic testing of the index subjects and their parents (or other biological family members if parents are not available) will be assessed for potential heritable causes of sudden death. By combining the wide catchment base of the San Diego Medical Examiner's Office, sequencing expertise of SD-based collaborators, computing power of the San Diego Supercomputer Center and in-house and external genomic analytics, the Scripps Translational Science Institute aims to provide a more complete characterization and understanding of the genetic causes of sudden death. Ultimately, findings from this study will be utilized to identify previously unrecognized mechanism of sudden death allowing for the development of preventative screening programs and potentially life-saving interventions.

Primary Outcome Measures

Name	Time	Method
Heritable causes of sudden death	3 years	The primary endpoint for this study is the discovery of genomic information that may help identify a potential cause of death in the index case. This information may inform living, biologically related family members of their potential risk and need for further genomic analysis.
