Welcome to the Dutch site for Rendu Osler Weber disease (Hereditary Haemorrhagic Telangiectasia or HHT).

HHT is fairly rare and therefore relatively unknown. As a consequence, doctors often have little experience or knowledge of the disease. It is a complex disorder involving both a genetic susceptibility and other internal or external (environmental) factors.

This site provides up-to-date information about HHT for patients, relatives and medical professionals who are involved with HHT.
