About HHT

Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder that  causes malformed blood vessels and can affect multiple organs of the  body. The disorder is also sometimes referred to as Osler-Weber-Rendu  (OWR) after several doctors who studied HHT in the late 1800s. More than  a hundred years later, HHT is still often misdiagnosed and many doctors  do not understand all of its manifestations.
