Living with Arterial tortuosity syndrome

A rare connective tissue condition that causes twisting, narrowing, and bulging of the arteries and flexible joints.

Understanding Arterial tortuosity syndrome

Arterial tortuosity syndrome is a rare connective tissue disorder in which the arteries become unusually long, twisted, and curved.

Connective tissue gives strength and flexibility to blood vessels, skin, joints, and the digestive tract. Besides twisting, arteries may narrow or bulge (aneurysm). The syndrome can also cause very loose or stiff joints and soft, stretchy skin. It is noticed in infancy and childhood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Twisted arteries
  • Bulging aorta (aortic aneurysm)
  • Narrowed arteries, including lung arteries
  • Very flexible joints
  • Soft, stretchy skin
  • Hernias

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists, digestive system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in SLC2A10 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
