This study aims to delineate the clinical profiles of the hereditary transthyretin amyloid polyneuropathy (ATTRv-PN) patients with A97S variant from southern China and the molecular characteristics of this mutant protein. ⋯ This study provides valuable insights into the clinical and molecular characteristics of ATTRv-PN patients with A97S from South China, particularly regarding the differences in disease progression and stability features.

Reliable typing of amyloid is essential. Amyloid extraction from tissue enables immunochemical typing of the precursor protein using an enzyme-linked immunosorbent assay (ELISA). ⋯ We describe a highly specific ELISA panel for routine typing of the main amyloid types in fat tissue. Until more sensitive typing techniques will become generally available, typing easily visible amyloid in fat tissue using this ELISA panel is reliable, affordable and straightforward.
