Hereditary Transthyretin Amyloidosis (hATTR) Market is expected to reach USD 9.2 billion by 2034

Hereditary transthyretin amyloidosis (hATTR) is a rare, progressive, life-threatening disease caused by mutations in the TTR gene, leading to the misfolding of transthyretin protein and deposition of amyloid fibrils in nerves, heart, and other organs. Patients typically present with polyneuropathy, cardiomyopathy, autonomic dysfunction, and gastrointestinal issues, making it a highly complex condition.

Historically underdiagnosed and undertreated, hATTR has seen a revolution in the last decade with the emergence of disease-modifying therapies, including TTR stabilizers, gene silencers, and RNA interference drugs. Increasing availability of genetic testing and newborn screening programs are also improving early detection, creating significant market growth potential.

Market Overview
• Market Size (2024): USD 4.1 billion
