Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder, affecting approximately 1 in 5000 persons. It is an "equal opportunity disorder"; all ethnicities and both genders are similarly affected. Learn more about HHT >
Most children with HHT have normal, healthy childhoods, with or without nosebleeds. Pulmonary AVMs may develop before puberty, but complications in asymptomatic children are extremely rare. However, cerebral AVMs, which are generally present at birth, can bleed in childhood.
