Multisystemic Smooth Muscle Dysfunction Syndrome

Description

Multisystemic smooth muscle dysfunction syndrome is a rare, genetic, vascular disease characterized by congenital dysfunction of smooth muscle throughout the body, manifesting with cerebrovascular disease, aortic anomalies, intestinal hypoperistalsis, hypotonic bladder, and pulmonary hypertension. Congenital mid-dilated pupils non-reactive to light associated with a large, persistent patent ductus arteriosus are characteristic hallmarks of the disease.
