Official Title: Impact of Elastin Mediated Vascular Stiffness on End Organs
Brief Summary:
Background:
People with Williams Syndrome (WS) and supravalvular aortic stenosis (SVAS) have less elasticity in their blood vessels. This is called blood vessel stiffness. Blood vessels may have focal narrowings called stenoses or may just be globally more narrow.
Objectives:
Researchers want to see how blood vessel differences in people with Williams Syndrome and supravalvular aortic stenosis affect organs in the body including the heart, gut, kidneys, and brain.
Eligibility:
People ages 5-85 who have WS or SVAS
Healthy volunteers ages 5-85
Design:
