Local doctors and medical authorities are taking the first steps to find answers to these kinds of questions by preparing for a new type of autopsy. Called a molecular autopsy, it uses genetic testing to discover if there are inherited medical problems, usually heart-related, in victims who die suddenly from no apparent cause. The samples will be kept for possible later use for genetic testing for victims of sudden, unexplained deaths, particularly infants, children and young adults. [...] is the time to start unraveling the mystery, and the possible risks to survivors, posed by unexplained deaths, doctors say. Physicians at the Mayo Clinic will be doing a molecular autopsy on Camden Hillard, via a research project at the Minnesota facility, as the child died shortly before the sample collection and move toward more organized genetic testing began here. Diamantoni sees several unexplained deaths every year, often among infants or among people in the Plain Sect population, who may be subject to one of a number of underlying genetic conditions particular to that group. Chowdhury says such testing is very important to parents, who are wondering if their surviving children are in danger from a genetic disorder that felled a child, or if future children could be at risk of a disorder.
