Transthyretin monomers: a new plasma biomarker for pre-symptomatic transthyretin-related amyloidosis.

Abstract excerpt

BACKGROUND: Genotyping and amyloid fibril detection in tissues are generally considered the diagnostic gold standard in transthyretin-related amyloidosis. Patients carry less stable TTR homotetramers prone to dissociation into non-native monomers, which rapidly self-assemble into oligomers and, ultimately, amyloid fibrils. Thus, the initial event of the amyloid cascade produces the smallest transthyretin species:...
