Single gene defect can cause stroke, other artery diseases

"For the first time, scientists have discovered a single gene defect that causes thoracic aortic aneurysms and dissections as well as early onset coronary artery disease, ischemic stroke and Moyamoya disease. The research is led by scientists at The University of Texas Health Science Center at Houston. The study, "Mutations in Smooth Muscle Alpha-Actin (ACTA2) Cause Early Onset Coronary Artery Disease, Stroke and Moyamoya Disease, Along with Thoracic Aortic Aneurysms and Dissections," was published early online April 30 in the American Journal of Human Genetics." - GEN
