Heart Arrhythmia in Myotonic Dystrophy Patients Traced to Mutant RNA in Study
New research suggests that heart arrhythmia in myotonic dystrophy (DM) patients is caused by mutant RNA in the heart’s sodium channel. The study, which adds to the understanding of this symptom, was titled “Splicing misregulation of SCN5A contributes to cardiac-conduction delay and heart arrhythmia in myotonic dystrophy,” and published in …
