BACKGROUND: Fabry Disease is a X-linked lysosomal storage disorder caused by the deficient activity of α-galactosidase A due to mutations in the GLA gene, which may be associated with increased left ventricular wall thickness, and mimic the morphologic features of hypertrophic cardiomyopathy. Management strategies for these two diseases diverge, with Fabry disease-specific treatment utilizing recombinant α-galactosidase A enzyme replacement therapy. METHODS: We studied a prospectively assembled consecutive cohort of 585 patients (71% male) from two hypertrophic cardiomyopathy tertiary referral centers by screening for low α-galactosidase A activity in dried blood spots...

BACKGROUND/AIMS: Fabry disease (FD), an X-linked lysosomal storage disorder, leads to accumulation of globotriaosylceramide. Screening in dialysis patients may identify genetic variants of unknown clinical significance. We aimed to characterize the pathogenicity of a novel GLA gene mutation identified during hemodialysis screening and the histologic findings of early Fabry nephropathy. METHODS: One out of 108 male hemodialysis patients screened for FD presented low α-galactosidase A activity...

Our objective was to examine the prevalence of Fabry disease in Russian children with chronic pain in the distal limbs. This non-interventional, multi-centre study included children 2-18 years of age with chronic recurrent unilateral or bilateral pain, burning, or acroparesthesia in the hands or feet. The presence of Fabry disease was defined by abnormal alpha-galactosidase A activity in males or alpha-galactosidase gene (GLA) mutation in females. Among 214 patients (110 males), 84.1% had bilateral limb pain and 31...

We aimed to explore the prevalence of Fabry disease in Thai patients who were diagnosed with end-stage renal disease (ESRD) of an unknown origin. Venous blood samples were collected from ESRD patients for biochemical and molecular studies. Alpha-galactosidase A (α-GAL A) screening was performed from dried-blood spots using fluorometry. Molecular confirmation was performed using DNA sequencing of the GLA gene. A total of 142 male and female patients were included in this study. Ten patients (7.04%) exhibited a significant decrease in α-GAL A activity...

The clinical significance of the c.427G>A (p.A143T) variant in GLA is a topic of debate within the lysosomal storage disease community. A review of the literature and published case reports found the clinical impact of the variant to range from classic Fabry symptoms to healthy unaffected males with normal alpha- galactosidase enzyme levels, leaving clinicians unsure of how to manage these individuals. As the number of states testing for Fabry disease on their newborn screening panel has increased, more people with this variant are being identified...

BACKGROUND: The onset of coeliac disease (CD) in the first year of life is uncommon and the diagnosis can be challenging due to the suboptimal sensitivity of tissue transglutaminase antibodies (tTG) at this age and the many other possible causes of malabsorption in infants. Antibodies to deamidated gliadin peptides (anti-DGPs), especially IgG, may appear earlier than IgA anti-tTG in very young children with CD. CASE PRESENTATION: We report here on an 8-month-old child who was evaluated for failure to thrive, constipation and developmental delay...

Importance: Diagnostic screening for Anderson-Fabry cardiomyopathy (AFC) is performed in the presence of specific clinical red flags in patients with hypertrophic cardiomyopathy (HCM) older than 25 years. However, left ventricular outflow tract obstruction (LVOTO) has been traditionally considered an exclusion criteria for AFC. Objective: To examine a series of patients diagnosed with HCM and severe basal LVOTO undergoing myectomy in whom the diagnosis of AFC was suspected by the cardiac surgeon intraoperatively and confirmed by histological and genetic examinations...

Anderson-Fabry disease (AFD) is an X-linked recessive, multisystem disease of lysosomal storage. A mutation in the gene encoding the hydrolase enzyme α-galactosidase A results in its deficiency, or complete absence of activity. Subsequent progressive intracellular accumulation of glycosphingolipids, predominantly globotriaosylceramide, in various tissues, results in progressive organ dysfunction and failure, most commonly affecting the kidneys, nervous system, skin, eyes, vascular endothelium, and the heart...

Fabry disease is an X-linked disorder resulted from deficiency of α-galactosidase A (GLA) activity. In Taiwan, a total of 792,247 newborns were screened from 2008 to 2014 in two newborn screening centers, and 13 variants of uncertain significance (VOUS) in the GLA gene were identified. To determine whether these variants were pathogenic or not, functional, biochemical, clinical and pedigree analyses were performed. In vitro functional assay was established through site-directed mutagenesis, and four in silico tools were used to predict pathogenesis...
