Roughly 80% of people with myotonic dystrophy – a common form of muscular dystrophy – experience dangerous heart ailments, and heart rhythm defects are the second-leading cause of death in those with the condition. In a new study, researchers traced the molecular events that lead to heart abnormalities in myotonic dystrophy and recreated the disease in a mouse model.

They report their findings in the journal Developmental Cell.

The grant to Prof. Kalsotra provides $300,000 over a three-year period to study the molecular basis for cardiac arrhythmias in Myotonic Dystrophy, a multi-systemic disease that affects about 1 in 8000 people with no cure.
