Overview
Fabry's disease can be classified based on its different phenotypes. Its different phenotypes are: classic and late-onset.
Classification
Based upon Phenotypes[1] [2]
| Age of onset | Severity | alpha-Gal A activity | Average age of death | |
|---|---|---|---|---|
| Classic | Childhood (mostly) | Severe | No activity or<1% of the normal mean | 41 years |
| Atypical (later onset) | Third to seventh decades | Less severe | 2 to 30% of the normal mean | >60 years[3] |
*Heterozygous females can be categorized in both groups based on the severity of the disease, from severe classic ones to less severe atypical and even no symptoms.[4]
Based upon complications
- Cardiac variant
- Renal variant
- Non-neuropathic form
- Neuropathic form
- Infantile form
- Juvenile form
