Background: Anderson-Fabry disease (AFD) is a rare X-linked lysosomal storage disease, caused by defects of the alpha-galactosidase A (GLA) gene. AFD can affect the heart, brain, kidney, eye, skin, peripheral nerves, and gastrointestinal tract. Cardiology (hypertrophic cardiomyopathy), neurology (cryptogenic stroke), and nephrology (end-stage renal failure) screening studies suggest the prevalence of GLA variants is 0.

Emerging observations reveal that mitochondrial impairment and oxidative stress may be implicated in the pathogenesis of FD. To investigate if specific genetic polymorphisms within the mitochondrial genome (mtDNA) could act as susceptibility factors and contribute to the clinical expression of FD, we have genotyped European mtDNA haplogroups in 77 Italian FD patients and 151 healthy controls.

- * Out of the cohort, 2 patients were found with a variant of the gene linked to FD, resulting in a prevalence rate of 0.9%, suggesting that FD is not very common but should still be considered when diagnosing juvenile stroke.
- * The results underline the importance of screening for FD in young patients with strokes, especially those with relevant personal or family medical histories, to improve diagnosis and treatment strategies.
Fabry's disease is a rare lysosomal storage disorder caused by the deficiency of α -galactosidase A that leads to the accumulation of neutral glycosphingolipids in many organs including kidney, heart, and brain. Since end-stage renal disease represents a major complication of this pathology, the aim of the present work was to evaluate if urinary proteoglycan/glycosaminoglycan excretion could represent a useful marker for monitoring kidney function in these patients at high risk. Quali-quantitative and structural analyses were conducted on plasma and urine from 24 Fabry's patients and 43 control subjects.

Since in Fabry disease (FD), specific cerebrovascular lesions are present, we thought to investigate motor cortex excitability, using transcranial magnetic stimulation.
Methods: Resting (RMT) and active (AMT) motor threshold, input-output curve (IN-OUT), central motor conduction time (CMCT), cortical silent period (cSP), short and long interval intracortical inhibition (SICI and LICI), intracortical facilitation (ICF), short interval intracortical facilitation (SICF) and short afferent inhibition (SAI) were measured in the cortical representation of the right first dorsal interosseous muscle in 11 patients with FD and 11 sex- and age matched healthy subjects.
