Is there a link between any other disease and hereditary hemorrhagic telangiectasia?

Complications: While hht is a stand alone genetic disease - because it can affect a variety of organs there are several associated complications including iron deficiency anemia (from bleeding), pulmonary hypertension or high output cardiac failure - from avms. Rarely, hht is associated with juvenile polyposis (comes from mutation in 1 of the 3 genes known to cause hht) and requires additional care.
