Molecular autopsy for sudden death in Japan

Area of Science:

• Forensic Pathology
• Medical Genetics
• Toxicology

Background:

• Japan employs diverse death investigation systems, all utilizing standard examinations like postmortem CT and histology.
• Morphological abnormalities are detectable via standard methods, but non-morphological causes of death require advanced techniques.
• Sudden, unexplained deaths, especially in the young, often stem from non-morphological conditions like inherited arrhythmias or metabolic disorders.

Purpose of the Study:

• To review molecular autopsy reports and case experiences from Japan.
• To highlight the utility of molecular autopsy and postmortem genetic analyses in death investigations.
• To explore the connection between drug-related fatalities and genetic variations.

Main Methods:

• Review of molecular autopsy reports and case studies from Japan.
• Analysis of postmortem genetic testing for inherited conditions.
• Examination of genetic variants in drug-related deaths.

Main Results:

• Molecular autopsy and genetic analyses effectively detect non-morphological causes of death, such as inherited arrhythmias and metabolic diseases.
• Case studies illustrate the successful application of these methods in identifying causes of sudden death in infants and young people.
• The review discusses the interplay between genetic factors and drug-induced fatalities.

Conclusions:

• Molecular autopsy is a vital tool for uncovering the causes of death when morphological findings are absent.
• These advanced genetic examinations hold the potential to be integrated as routine procedures in death investigations.
• Implementing molecular autopsy can provide critical information to prevent future deaths and save lives.
