| Outline of Final Research Achievements |
In most cases of sudden death, cause and manner of death can be established, with many attributable to cardiac abnormalities at autopsy. A significant number of sudden cardiac deaths, however, particularly in young people,remains unexplained following a comprehensive medicolegal investigation, including autopsy and laboratory tests.
In this study, comprehensive screening of cardiac ion channel gene, SCN5A were preformed in sudden cardiac death. One mutation(p.Phe532Cys) was detected in only acute heart failure and dilated cardiomyopathy cases. This mutation was analyzed by using Polyphen2. p.Phe532Cys had Polyphen2 score of 0.999 (Probably damaging). It would be desirable to survey other disease-causing genes to determine a more accurate prevalence of gene mutations in sudden cardiac death.
