Splicing misregulation of SCN5A contributes to cardiac-conduction delay and heart arrhythmia in myotonic dystrophy

Splicing misregulation of SCN5A contributes to cardiac-conduction delay and heart arrhythmia in myotonic dystrophy

Patients with myotonic dystrophy (MD) suffer from severe cardiac issues of unknown aetiology. Freyermuth et al. show that fatal changes in cardiac electrophysiological properties in humans and mice with MD may arise from misregulation of the alternative splicing of the cardiac Na+ channel SCN5Atrans...

Sumario:Patients with myotonic dystrophy (MD) suffer from severe cardiac issues of unknown aetiology. Freyermuth et al. show that fatal changes in cardiac electrophysiological properties in humans and mice with MD may arise from misregulation of the alternative splicing of the cardiac Na+ channel SCN5Atranscript, resulting in expression of its fetal form.
