Fabry disease (FD) is a multisystem lysosomal storage disorder induced by genetic variants in the alpha-galactosidase A (GalA) gene. Some FD patients have GLA variants with a reduction in overall GalA enzymatic activity due to mutated proteins with reduced stability, caused by protein misfolding and premature degradation, but the GalA catalytic activity remains conserved ("amenable" genetic variants). To correct this misfolding and to prevent premature degradation, migalastat, a small iminosugar molecule was developed.

Fabry disease is a lysosomal storage disorder caused by the deficiency of the α-galactosidase-A enzyme. The result is the progressive accumulation of complex glycosphingolipids and cellular dysfunction. Cardiac, renal, and neurological involvement significantly reduces life expectancy.

Nephropathy is a major Fabry disease complication. Kidney biopsies reveal glomerulosclerosis even in pediatric patients. The main manifestations of Fabry nephropathy include reduced glomerular filtration rate and proteinuria.

Introduction: Nephropathy is one of the major complications of Fabry disease and mainly includes reduced glomerular filtration rate and proteinuria. Affected patients show different degrees of annual loss of renal function according to the magnitude of proteinuria and decrease in estimated glomerular filtration rate (eGFR) at the baseline.

Objetive: To analyze the relationship between age at diagnosis and severity of nephropathy in a Fabry disease population.

Introduction: In advanced Fabry nephropathy stages, enzyme replacement theraphy (ERT) efficacy decreases, due to its impossibility to reverse renal fibrosis. Therefore, the finding of early kidney fibrosis biomarkers in affected patients is of interest. During renal fibrosis miR-21, miR-192 and miR-433 (fibrosis promotors) are activated by transforming growth factor- (TGF-), and miR-29 and miR-200 family (fibrosis supressors) are inhibited by TGF-.

Renal involvement is associated with a greater morbidity and mortality in Fabry disease. Pathological albuminuria, the first Fabry nephropathy clinical manifestation, can occur from early childhood, although histological lesions such as tubulo-interstitial fibrosis and glomerulosclerosis are present or may precede the onset of pathological albuminuria. In renal cells, exposure to Lyso-Gb3 is correlated with increased expression of Transforming Growth Factor-eta (TGF-).

Fabry disease (FD) is an X-linked lysosomal storage disorder resulting from the deficiency or absence of the alpha galactosidase A enzyme. Organic involvement in men is well known, but in women it is controversial, partly due to the random X-chromosomes inactivation (Lyon hypothesis). The aim of this study was to describe the organic involvement in women at the time of FD diagnosis.

Fabry disease is an X-linked lysosomal storage disorder resulting from the deficiency or absence of the enzyme alpha galactosidase A; this defect leads to the systemic accumulation of globotriaosylceramide and its metabolites. Organic involvement in men is well known, but in women it is controversial, mainly due to the random X-chromosome inactivation in each of their cells (Lyon hypothesis). This would explain why women (heterozygotes) present a wide variability in the severity of their phenotype.

Nephropathy is one of the major complications of Fabry Disease (FD) and mainly includes reduced glomerular filtration rate (GFR) and proteinuria. Despite the frequency, scarce information exists regarding the frequency of CKD as well as other related complications in FD patients in Argentina. The aim of the study was to measure the prevalence of CKD at diagnosis of FD as well as to describe other related conditions in a large cohort of patients with FD.
