The integration of microscopic and genetic information is particularly important in forensic settings, since the high prevalence of pathogenic SCN5A variants in young victims of BrS arrhythmias tends to suggest that SCD in BrS is substantially of electric nature in the young age, while a structural contribution mainly concerns the SCD in adult age, that represent most of the event's (31). This evidence concerns the gene SCN5A and cardiac arrhythmia.
