Sudden deaths that have no apparent cause are a major challenge in modern cardiology. These deaths are often due to hidden heart problems, but sometimes forensic experts are unable to determine the exact cause of death. Genetic autopsies, which involve molecular analysis of the corpse to detect alterations in genes that may explain the sudden death, are becoming more popular. These autopsies are able to identify genetic mutations that can cause sudden death, and they may also help prevent other sudden deaths in relatives who may be at risk. The availability of autopsies and genetic testing is crucial in determining the cause of death and identifying any hereditary diseases.
