Family genetics are the main cause of TTR-FAP. People who have TTR-FAP have a genetic mutation in the transthyretin (TTR) gene that can result in abnormal and unstable transthyretin proteins. This means that it can be inherited from either one of your biological parents, even if neither of them has developed signs or symptoms of the disease.

For some patients, a family history can be helpful in getting an early diagnosis. That's why you should work closely with your doctor and always discuss diseases and symptoms your family members have experienced.

If you have been diagnosed with TTR-FAP, ask your healthcare professional about genetic testing. It can help identify other family members who may have the genetic mutation that can put them at risk for developing the disease.
