Hereditary ATTR Amyloidosis - A Closer Look at an Inherited Condition

hATTR amyloidosis is a rare condition that affects an estimated 50,000 people worldwide. It is caused by an inherited gene variant, or change, in the transthyretin (TTR) gene. This change in the TTR gene may also be referred to as a mutation. Different symptoms may appear at different times for each person with hATTR amyloidosis. Symptoms can affect several parts of the body, including the nerves, heart, and digestive system.

The symptoms of hATTR amyloidosis can vary widely among people with the condition, even within families. The age that symptoms 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.
