Arterial tortuosity syndrome (ATS; MIM 208050) is an autosomal recessive disorder characterized by tortuosity, elongation, and aneuryms of major arteries and the aorta. Additional cardiovascular findings may include aberrant origin of aortic branches, aortic stenosis, pulmonary artery or pulmonary valve stenosis or stenosis of additional arteries, and vasomotor more
