Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Shaghayegh Habibi, M.D.[2]
Overview
Renal amyloidosis can be classified according to the site of amyloid deposition into glomerular, vascular, and tubular amyloidosis.
Classification
Renal amyloidosis may be classified according to site of amyloid deposition into 3 subtypes:[1]
- Glomerular amyloid deposition (more common and have a poorer prognosis)
- Vascular amyloid deposition
- Tubular amyloid deposition
Renal amyloidosis may be classified according to type of amyloidogenic protein into 3 subtypes:[2]
| Amyloidosis type | Amyloidogenic protein | |
|---|---|---|
| Common types | AL/AHL/AH
(Primary amyloidosis) |
Ig light chains (AL) |
| Fragments of Ig heavy chains and light chains (AHL) | ||
| Fragments of heavy chains only (AH) | ||
| AA
(Secondary amyloidosis) |
Serum amyloid A | |
| Rare types | AFib | Fibrinogen A α chain |
| AApo AI/AII/AIV | Apo AI, Apo AII, or Apo AIV | |
| ATTR | Transthyretin | |
| ALys | Lysozyme | |
| AGel | Gelsolin | |
| ALECT2 | Leukocyte chemotactic factor 2 |
