Understanding Hereditary ATTR Amyloidosis
Hereditary ATTR (hATTR) amyloidosis is an inherited, progressive disease caused by a genetic mutation that results in the misfolding of transthyretin (TTR) proteins. This results in the formation of amyloid fibrils that could deposit in the nerves, heart, and/or gastrointestinal (GI) tract.
hATTR amyloidosis affects approximately 50,000 people worldwide. Many people remain undiagnosed or misdiagnosed.
