Immunocytochemical methods were used to study the nature of the amyloid deposits in the Finnish type-familial amyloid polyneuropathy (FAP) type IV, which is characterized by cranial neuropathy and corneal lattice dystrophy. Commercial antisera to human plasma transthyretin (prealbumin) did not stain the amyloid deposits, but in every case a positive staining was obtained with antibodies raised ...

We describe the first case from India of ALECT2 amyloidosis. An adult Punjabi male presented with progressive renal dysfunction and non-nephrotic range proteinuria. Serum protein electrophoresis and immunofixation were normal, with mildly elevated serum free light chain ratio. A renal biopsy confirmed the presence of amyloid. Immunohistochemistry was negative for monoclonal light chains. Proteo...

The diverse spectrum of amyloid related diseases is now recognised to include Alzheimer’s disease, type II diabetes, and the transmissible spongiform encephalopathies.
