Fabry's disease: report of a case
1Department of Neurology, Chang Gung Medical College and Memorial Hospital, Taipei, Taiwan, ROC.
Summary
Fabry's disease, a rare genetic disorder, presents unique clinical features in Taiwan. This case highlights key symptoms and diagnostic markers for this glycosphingolipid metabolism disorder.
Area of Science:
- Biochemistry
- Genetics
- Neurology
Background:
- Fabry disease is a rare X-linked hereditary disorder affecting glycosphingolipid metabolism.
- Clinical manifestations of Fabry disease in Taiwan are not well-documented.
Observation:
- A 32-year-old Taiwanese man presented with acroparesthesia, skin angiokeratomas, corneal opacity, and mitral valve prolapse.
- Neurological involvement included central motor pathways and autonomic nervous system dysfunction.
- Renal insufficiency was also noted.
Findings:
- Sural nerve biopsy revealed loss of small myelinated and unmyelinated fibers.
- Reduced serum alpha-galactosidase A activity was observed.
- Elevated urinary globotriaosylceramide confirmed the diagnosis.
Implications:
- This case expands the understanding of Fabry disease's clinical spectrum in Taiwan.
- Highlights the importance of recognizing diverse symptoms for early diagnosis.
- Emphasizes the utility of enzyme assays and metabolite analysis in confirming the diagnosis.
