Samples used in molecular autopsy: an update

Abstract

Molecular autopsy makes it possible to identify the genetic alteration responsible for an inherited arrhythmogenic disease, main suspected cause of sudden death in cases that remain unexplained after a complete medico-legal autopsy. By using next-generation sequencing technology, a massive genetic study can be carried out that identifies a rare variant classified as potentially pathogenic in up to 25% of sudden death cases in the young population. To carry out a post-mortem genetic study, it is necessary to have samples in suitable conservation conditions. Our chapter focuses on the type of samples that are used today in massively parallel genetic analyses.
