[5-8] The analysis of DNA from a deceased individual with the aim of identifying genetic variants associated with or causative of a fatal disease (particularly those with a sudden onset) is referred to as a molecular autopsy. The genetic variants targeted during a molecular autopsy are most often associated with diseases that do not manifest with obvious and specific pathological changes.
Studies have shown varying degrees of resolution of previously undetermined cases following a molecular autopsy, with Anderson et al.
"Whole-exome molecular autopsy
with gene-specific surveillance is an effective approach for the detection of potential pathogenic variants in SUDY cases," the authors write.
The largest series of studied results of molecular autopsy
showed that the largest number of SUD (33%) occurred in dream or during exercise (19).
Keeping this in mind, molecular autopsy
should be considered as a part of medicolegal investigation in sudden cardiac deaths without structural alterations.
[3,9,13,19] Advances in postmortem genetic testing (so-called 'molecular autopsy
') have made it possible to identify an underlying genetic cause for some sudden unexpected deaths, indicating a cardiac-related cause of death in 35% of these deaths in children and in 10-15% of cases of SIDS.
ese drew a blank as did biochemistry and Another doctor, Kay Metcalfe, a consultant clinical geneticist, arranged for a molecular autopsy
to be carried out to try to 'nd out what had been happening in Dexter's heart.

This Illumina and UNTHSC partnership will focus on projects, including a range of forensically relevant genetic markers for human identity testing, pharmacogenetics for molecular autopsy
, microbial forensics, and additional markers and methods to generate investigative leads in criminal cases and matters of national security.
