Overview
Amyloidosis may be classified on the basis of type of amyloidogenic protein and associated clinical syndromes into primary (AL) amyloidosis, secondary (AA) amyloidosis, familial (AF) amyloidosis, transthyretin (ATTRwt) amyloidosis and dialysis-associated (AH) amyloidosis. It can also be classified based on extent of organ system involvement.

Overview
Classification
Amyloidosis may be classified based on precursor of amyloidogenic protein into different subtypes, include:[1][2]
| Type | Amyloidogenic protein/ fibril | Clinical syndrome |
|---|---|---|
| AL | Light chains of immunoglobulines (most common type) | Monoclonal gammopathy |
| AA | Serum amyloid A protein | Chronic inflammatory diseases |
| AF | Mutant transthyretin, A1-apolipoprotein, gelsolin, fibrinogen, etc. | Familial polyneuropathy/cardiomyopathy/nephropathy |
| ATTRwt | Wild-type transthyretin | Senile restrictive cardiomyopathy _ Transthyretin-related amyloidosis wild-type |
| AH | ß2-microglobulin | Long-term hemodialysis |
