Supravalvular aortic stenosis (SVAS; MIM 185500) is an autosomal dominant disorder caused by mutations in the elastin (ELN) gene.  The wall of the aorta is greatly thickened in SVAS resulting in narrowing of the ascending aorta.  In addition to SVAS, many patients also have peripheral pulmonary stenosis and some patients may exhibit stenoses of other arteries.  Considerable intrafamilial phenotypic variation has been observed and the penetrance is reported toread more
