Genomic screening of Fabry disease in young stroke patients: the Taiwan experience and a review of the literature.

ABSTRACT:

Background and purpose

Fabry disease is an X-linked disease, and enzyme-based screening methods are not suitable for female patients.

Methods

In total, 1000 young stroke patients (18-55 years, 661 with ischaemic stroke and 339 with hypertensive intracerebral hemorrhage) were recruited. The Sequenom iPLEX assay was used to detect 26 Fabry related mutation genes. The frequency of Fabry disease in young stroke was reviewed and compared between Asian and non-Asian countries.

Results

Two male patients with ischaemic stroke were found to have a genetic mutation of IVS4+919G>A. There was no ?-galactosidase A (GLA) gene mutation in female patients. The frequency in Asian stroke patients was 0.62% (male vs. female 0.63% vs. 0.58%) with 0.72% for ischaemic stroke and none for hemorrhagic stroke, compared to 0.88% (0.77% vs. 1.08%) with 0.83% for ischaemic stroke and 1.40% for hemorrhagic stroke reported in western countries.

Conclusion

IVS4+919G>A is the GLA mutation in Taiwanese young ischaemic stroke patients. Fabry disease is more frequent among non-Asian patients compared to Asian patients.
