Hereditary Hemorrhagic Telangiectasia (HHT) Center

The Mass General HHT Center offers compassionate, family-centered multidisciplinary care. We strive to create an “HHT medical home” by offering a wide range of specialists, education and treatments while working with a person’s primary care provider.


Diagnosing HHT

  • Individual and family history, especially nosebleeding
  • Focused examination, especially telangiectases
  • Review of HHT Clinical Guidelines
  • Consideration of DNA-based testing
  • Genetic counseling

The Mass General HHT Center offers diagnosis, genetic counseling, multidisciplinary evaluations, and care coordination for people with this common (1/5000) genetic condition.  Our team works with a person’s primary-care provider to identify specialty care needs to improve outcomes.  We strive to create an “HHT medical home” while offering a wide range of specialists, treatments and education for the patient and their family.

About this program and our multidisciplinary team

Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Rendu-Weber Syndrome, often results in nosebleeds and other bleeding problems throughout the body. The Mass General HHT Center emphasizes the importance of the first step of making the correct diagnosis. We provide confirmatory genetic testing, genetic counseling, obtain multidisciplinary evaluations, and coordinate specialty care.  Our team works with a patient’s primary-care provider to identify specialty needs, which improve care and outcomes.

Our center includes Massachusetts General Hospital, MassGeneral Hospital for Children, and Massachusetts Eye & Ear Infirmary.  This collaboration allows us to provide specialized care across the lifespan.

Dr. Angela Lin provides genetics counseling, including the use of genetic testing. She coordinates a family centered approach to HHT care.

Patient Education

Organizations and websites

The HHT Foundation International, Inc. is the leading disease specific advocacy group for HHT. As their website notes, “HHT is an inherited disease that affects over 1 million people worldwide. It is characterized by defective blood vessels in the brain, lungs, liver, nose, skin, and intestines, and typically begins with nosebleeds during childhood. HHT is highly treatable but can result in serious health problems if not promptly diagnosed and treated.”

  • Understanding HHT

    Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder that affects blood vessels. This handout will discuss HHT, the causes and signs of HHT, how doctors test for it and how doctors diagnose it.
