A simple method for quantification of plasma globotriaosylsphingosine: Utility for Fabry disease

Molecular Genetics and Metabolism, 2017
Fabry disease (FD) results from impaired globotriaosylceramide (Gb3) catabolism, due to a deficiency of the lysosomal hydrolase, α-galactosidase A (α-GalA). As a direct consequence, the deacetylated derivative, globotriaosylsphingosine (lyso-Gb3), is produced and contemporary evidence exemplifies its use as a biomarker.

Mutant α-galactosidase A with M296I does not cause elevation of the plasma globotriaosylsphingosine level

Molecular Genetics and Metabolism, 2012
Recently, plasma globotriaosylsphingosine (lyso-Gb3) has attracted attention as a biomarker of Fabry disease. However, we found a subset of Fabry disease patients who did not show any increase in the plasma lyso-Gb3 concentration, although other patients exhibited apparent enhancement of it. This subset predominantly exhibited the clinical phenotype of

Combined analysis of plasma or serum glucosylsphingosine and globotriaosylsphingosine by UPLC-MS/MS

Clinica Chimica Acta, 2020
To develop a method for the combined analysis of plasma and serum glucosylsphingosine (lyso-Gb1) and globotriaosylsphingosine (lyso-Gb3), biomarkers of Gaucher disease (GD) and Fabry disease (FD), respectively.Internal standards were added to 100 µL of plasma/serum and glycosphingolipids: lyso-Gb1, lyso-Gb3, and galactosylsphingosine (GalSph) were ...

Urinary Globotriaosylsphingosine-Related Biomarkers for Fabry Disease Targeted by Metabolomics

Analytical Chemistry, 2012
Fabry disease is a lysosomal storage disorder caused by deficiency of α-galactosidase A, resulting in glycosphingolipid accumulation in organs and tissues, including plasma and urine. Two disease-specific Fabry biomarkers have been identified and quantified in plasma and urine: globotriaosylceramide (Gb(3)) and globotriaosylsphingosine (lyso-Gb(3 ...

Favourable effect of early versus late start of enzyme replacement therapy on plasma globotriaosylsphingosine levels in men with classical Fabry disease

open access: yesMolecular Genetics and Metabolism, 2017
Background: The level of plasma globotriaosylsphingosine (lysoGb3) is an indication of disease severity in Fabry disease (FD) and its decrease during enzyme replacement therapy could be a reflection of treatment efficacy.

Tissue and plasma globotriaosylsphingosine could be a biomarker for assessing enzyme replacement therapy for Fabry disease

Biochemical and Biophysical Research Communications, 2010
Fabry disease is a genetic disease caused by a deficiency of alpha-galactosidase A (GLA), which leads to systemic accumulation of glycolipids, predominantly globotriaosylceramide (Gb3). With the introduction and spread of enzyme replacement therapy (ERT) with recombinant GLAs for this disease, a useful biomarker for assessing the response to ERT is ...

The clinical utility of total concentration of urinary globotriaosylsphingosine plus its analogues in the diagnosis of Fabry disease

Clinica Chimica Acta, 2020
Fabry disease (FD) is a genetic disorder caused by defective α-galactosidase-A enzyme due to mutations in the GLA gene. A reliable diagnosis in classical FD males can be made by measuring the enzyme activity while diagnosing classical FD females and non-classical FD patients requires mutation analysis.

Screening for Fabry Disease in Japanese Patients with Young-Onset Stroke by Measuring α-Galactosidase A and Globotriaosylsphingosine

Journal of Stroke and Cerebrovascular Diseases, 2018
Fabry disease is an X-linked lysosomal storage disorder caused by mutations in GLA, which encodes the enzyme α-galactosidase A (α-Gal A). Although the prevalence of Fabry disease in patients with stroke has been reported to range from 0% to 4%, few cohort studies have examined Japanese stroke patients.
