Abstract
Sudden cardiac death (SCD) is one of the most common causes of death worldwide with a higher frequency especially in the young. Therefore, SCD is represented frequently in forensic autopsy practice, whereupon pathological findings in the heart can explain acute death. These pathological changes may not only include myocardial infarction, coronary thrombosis, or all forms of myocarditis/endocarditis but also rare diseases such as hereditary structural or arrythmogenic anomalies, lesions of the cardiac conduction system, or primary cardiac tumours.

Abstract
Congenital long QT-syndrome (LQTS) is an inherited cardiac arrhythmia, which is characterized by a prolonged QT interval which predisposes to sudden cardiac death due to ventricular arrhythmias. The altered functions are based on different mutations in LQTS-associated genes. In this study, we performed a mutation analysis for the detection of 125 LQTS-associated single nucleotide polymorphisms (SNPs) focused on the genes KCNQ1, KCNH2, and SCN5A by using the SNaPshot multiplex minisequencing technique. Furthermore, we investigated 152 autopsy-negative cases from younger adults and infants, as well as samples from patients with clinically suspicion for LQTS, in which we found two types of variations.

Abstract
INTRODUCTION Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect caused by G6PD gene mutations. This study aimed to develop a cost-effective, multiplex, genotyping method for detecting common mutations in the G6PD gene. METHODS We used a SNaPshot approach to genotype multiple G6PD mutations that are common to human populations in South-East Asia. This assay is based on multiplex PCR coupled with primer extension reactions. Different G6PD gene mutations were determined by peak retention time and colors of the primer extension products. RESULTS We designed PCR primers for multiplex amplification of the G6PD gene fragments and for primer extension reactions to genotype 11 G6PD mutations. DNA samples from a total of 120 unrelated G6PD-deficient individuals from the China-Myanmar border area were used to establish and validate this method. Direct sequencing of the PCR products demonstrated 100% concordance between the SNaPshot and the sequencing results. CONCLUSION The SNaPshot method offers a specific and sensitive alternative for simultaneously interrogating multiple G6PD mutations.

Abstract
PURPOSE OF REVIEW Unexplained sudden death and the sudden arrhythmic death syndrome (SADS) affect a small but significant proportion of young and apparently healthy individuals. This review revisits the causes underlying such deaths and the investigational strategies that identify surviving family who may be at risk. RECENT FINDINGS Recent epidemiological data is available from case series or government records. The yield from familial cardiological evaluation for inherited conditions has been supported by additional small series. The greatest advance has come with molecular autopsy studies, which have utilized various methodologies and candidate genes to investigate SADS cases and their families. SUMMARY The latest research replicates and extends the existing knowledge regarding epidemiology and familial evaluation of SADS, whilst genetic studies support a role for the molecular autopsy.
