Speaking with your healthcare professional about hereditary ATTR (hATTR) amyloidosis

Learning about this condition and your family health history can help you have a conversation with your healthcare professional

The path to diagnosis

Symptoms of hATTR amyloidosis may be similar to those of other conditions.

The more educated you are about the symptoms, the better prepared you can be to speak with your healthcare professional about a possible diagnosis.

It’s important that you discuss all the symptoms you’re experiencing because your healthcare professional may choose to refer you to a specialist who could prescribe further tests to help make a diagnosis.

Genetic counseling

Genetic counseling can help you understand your chances of developing the condition as well as to make you familiar with the testing process and implications of a diagnosis. Genetic counselors can also help you understand the issues related to genetic testing—from personal risk to possible insurance impact, and can help you determine if a genetic test may be right for you.

A genetic test will tell a person if he or she carries a mutation in the TTR gene associated with hATTR amyloidosis. Once a gene mutation is identified, family members of an affected individual can use this information to help determine their own risk.
