The path to discussion and diagnosis
Hereditary ATTR (hATTR) amyloidosis is a rare disease which has symptoms that may be similar to those of other conditions. This may lead to misdiagnosis or delays in diagnosis.
The following steps can help you to have an informed conversation with your doctor and ensure he or she has the information needed to make an accurate assessment of your risk for hATTR amyloidosis.

Understand the importance of genetics
Genetic testing has opened a new horizon for the diagnosis and management of hereditary human disease. The results of a genetic test can confirm or rule out a suspected genetic condition, such as hATTR amyloidosis, or help determine a person’s chance of developing or passing on a genetic condition.
Because genetic testing is often associated with many ethical and psychosocial issues, professional genetic counselling is important so that the patient and family can comprehend the meanings and implications of a positive or negative test result.
Genetic testing and counseling may help to:
- Identify risk of disease for patients and their family members
- Shorten the time to diagnosis and prevent misdiagnoses
- Help doctors and patients make informed treatment decisions or consider clinical trials
- Provide information about support resources such as patient advocacy organizations
Genetic counselling is a service that provides information and support for people who have, or may be at risk for, genetic conditions. Genetic counsellors are trained healthcare professionals who can discuss genetics, inheritance, and disease risk as well as the benefits, limitations, and potential implications of genetic testing. Genetic counselling can be performed before, during, or after genetic testing and is often in tandem with the treatment pathway.
Talk to your doctor about the need and possibility for genetic testing to help progress diagnosis.
Know that treatment options are available
If you are diagnosed with hATTR amyloidosis, treatments are available that address the underlying cause of the disease. These therapies can help by decreasing the amount of TTR protein that’s made in the body. There are also treatments that bind to TTR proteins and help prevent them from forming clusters.
Liver and/or heart transplant is also an option for some patients who meet certain eligibility criteria.
Since the symptoms of hATTR amyloidosis can worsen over time, managing symptoms is an ongoing process. Doctors may prescribe medication to help manage some of the symptoms that may reduce the daily impact on patients. Additional treatment options for hATTR amyloidosis are currently being researched.
