What are the symptoms of hATTR amyloidosis?
The symptoms of hereditary ATTR (hATTR) amyloidosis can vary widely among people with the condition and even within families. Different symptoms may appear at different times for each person.
The age that symptoms of hATTR amyloidosis typically appear ranges from the mid-20s to the mid-60s. Because symptoms of hATTR amyloidosis can worsen over time, it's important to talk to your doctor about them as soon as possible.
hATTR amyloidosis affects several parts of the body, including:
The peripheral nervous system, which is made up of nerves that branch out from the brain and spinal cord and communicate with the rest of the body, including your arms and legs.
- Nerve damage in the peripheral nervous system results in improper function
The cardiac system, which is made up of the heart and blood vessels, transports blood through veins and delivers oxygen to cells in the body.
- Damage to the heart muscle can lead to heart failure
The autonomic nervous system, which is made up of nerves that connect the brain and spinal cord to organs such as the heart, stomach, and intestines.
- When the autonomic nervous system is not working correctly, it may affect involuntary bodily functions, such as breathing, digestion, and heart rate
