Genetic Variants Associated With Unexplained Sudden Cardiac Death in Adult White and African American Individuals
An original investigative study of 413 adults who had unexplained sudden cardiac death, nearly 1/5 of individuals had pathogenic or likely pathogenic genetic variants consistent with inherited cardiomyopathies or arrhythmia syndromes, despite having normal cardiac findings. Read more…
