Transthyretin Amyloidosis (ATTR) Plasma
Transthyretin Amyloidosis (ATTR) Plasma - human plasma from clinically confirmed ATTR donors, processed within 24 hours. ATTR amyloidosis is caused by misfolded TTR protein aggregating into amyloid fibrils affecting nerves and heart. Ideal for TTR stability assays, cardiac biomarker profiling, and pharmacodynamic monitoring of TTR stabilizers and gene-silencing therapies. Stratification by ATTRv/ATTRwt subtype, genotype, and phenotype.
Transthyretin Amyloidosis (ATTR) Plasma for Amyloid and Cardiac Biomarker Research
Our Transthyretin Amyloidosis (ATTR) Plasma is sourced from IRB-consented donors clinically diagnosed with ATTR amyloidosis, a progressive disease in which misfolded transthyretin (TTR) protein aggregates into amyloid fibrils that deposit in peripheral nerves and the heart. Each sample is processed and frozen within 24 hours of collection to preserve circulating TTR, natriuretic peptides, and other amyloid-relevant biomarkers.
ATTR Biology and Why Plasma
- ATTR amyloidosis arises from destabilized TTR tetramers – either due to inherited point mutations (hereditary/variant ATTR, ATTRv) or age-related misfolding of wild-type TTR (ATTRwt) – that dissociate into monomers prone to aggregation and fibril formation.
- Amyloid deposition in peripheral and autonomic nerves produces a length-dependent polyneuropathy, while cardiac deposition causes restrictive cardiomyopathy with progressive heart failure and conduction abnormalities.
- Plasma is the preferred matrix for TTR stability and concentration assays, and for cardiac biomarkers including NT-proBNP and troponin that track amyloid cardiomyopathy progression.
- Approved and investigational therapeutics target distinct mechanisms: TTR tetramer stabilizers (e.g. tafamidis), TTR gene-silencing therapies (patisiran, inotersen, vutrisiran), and CRISPR-based knockdown approaches, all of which rely on circulating TTR level and stability measurements for pharmacodynamic monitoring.
- Genotype (e.g. Val142Ile, Val50Met) and phenotype (predominantly neuropathic, cardiac, or mixed) are key stratification variables for both natural history and treatment-response research.
