Hereditary hemorrhagic telangiectasia (HHT or Osler-Weber-Rendu disease) is an autosomal dominant disorder of blood vessel formation affecting 1/8000-1/10,000 people.  Abnormal direct connections of arteries and veins in larger vessels manifest as arteriovenous malformations (AVMs) most often in the lungs, liver, and brain.


Genetic testing enables:

  • confirmation of diagnosis of HHT in symptomatic individuals
  • determination of disease status in at-risk family members
  • early detection of AVMs
  • opportunity for management to prevent or minimize complications of HHT
