Abstract

Hereditary hemorrhagic telangiectasia, also known as Osler-We-ber-Rendu disease, is a genetic autosomal dominantly inherited disorder that exhibits age-related penetrance. It is characterized by abnormal development of blood vessels, clinically manifesting with epistaxis, gastrointestinal bleeding, cutaneous telangiectasias, and arteriovenous malformations in internal organs like lungs, brain and liver. Genetic mutations affecting over 90% of cases are known and can be detected although diagnoses are made based on medical criteria.
