BACKGROUND: Fabry disease (FD) is known as a rare cause of stroke. Recent studies suggested that FD is an underdiagnosed entity among young stroke patients. We aimed to investigate the frequency of FD in young cryptogenic stroke patients who lived in the City of Sakarya and to define the clinical features that help in recognizing patients with FD.
METHODS: Acute ischemic stroke patients aged 18-55 years who were admitted to our hospital between October 2013 and September 2016 were evaluated for inclusion. Patients with other recognized causes of stroke were excluded. The screening was performed for alpha-galactosidase A (α-Gal A) activity on dried blood spot, and DNA was sequenced for GLA mutation in patients with low plasma α-Gal A activity.
RESULTS: Among the 484 acute ischemic stroke patients, 54 (24 male, 44.4%) young cryptogenic stroke patients were enrolled. The α-Gal A activity was detected as low in 3 patients. c.[680G > A] p.[R227Q] missense mutation was identified in 2 male patients. The frequency of FD was calculated as 3.7%.
CONCLUSIONS: Our research is the first FD screening study in Turkish stroke patients. Our results underlined the importance of considering FD during the etiologic evaluation of young cryptogenic stroke patients as it is a rare but potentially treatable entity.
