Defective RNA Processing Linked to Cardiac Problems Seen in Myotonic Dystrophy Patients

Researchers have discovered the molecular mechanisms responsible for the heart dysfunctions that mark myotonic dystrophy, and reported they appear to be linked to a defective processing of the cardiac sodium channel (SCN5A) RNA. Their study, published in Nature Communications, is titled “Splicing misregulation of SCN5A contributes to cardiac-conduction delay and…
