Genetic testing options


If your doctor thinks you may be at risk for hATTR amyloidosis, they may recommend you work with a genetic counselor. Genetic counselors are trained healthcare professionals who can help you and your family learn more about the condition, the chances of you and your family inheriting it, whether genetic testing is right for you, how testing works, and what may happen after a diagnosis.

A genetic test will determine whether a person carries a mutation in the transthyretin (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.

23andMe® logo

In addition to genetic tests ordered by your doctor, direct‑to‑consumer genetic services, like 23andMe, are available for purchase to help you learn more about how genetics may influence your risk for certain hereditary conditions.

Alnylam has teamed up with 23andMe to offer the Hereditary Amyloidosis (TTR-Related) Genetic Health Risk report, a consumer genetic service that looks for the 3 most common genetic mutations associated with hATTR amyloidosis. This report does not identify all TTR variants that can cause hATTR amyloidosis, nor does it diagnose hATTR amyloidosis or any other health conditions. Please talk to your doctor if this condition runs in your family, you think you might have this condition, or you have concerns about your results.

If you have a TTR variant detected by the 23andMe test, the Alnylam +myFamily program will provide 23andMe Health + Ancestry Service Kits to your first-degree family members (parents, full siblings, and biological adult children)—at no charge.a

a23andMe services provide information on a person's risk for certain diseases, but cannot provide a diagnosis. The Hereditary Amyloidosis (TTR-Related) Genetic Health Risk report provides information on the 3 most common TTR mutations in the United States. There are over 120 mutations associated with hATTR amyloidosis. If you have symptoms of hATTR amyloidosis or other symptoms you are concerned about, regardless of results reported by a 23andMe Health Risk report, it is important to talk to your doctor as soon as possible. Only a doctor can confirm a diagnosis of hATTR amyloidosis.
