Abstract
BACKGROUND Fabry disease (FD) is an X-linked, hereditary dysfunction of glycosphingolipid storage caused by mutations in the GLA gene encoding alpha-galactosidase A enzyme. In rare cases, FD may coexist with immunoglobulin A nephropathy (IgAN). We describe a case of concurrent FD, IgAN, and dilated cardiomyopathy-causing mutations in the TTN and BAG3 genes, which has not been reported previously. CASE PRESENTATION A 60-year-old female patient was admitted with a one-week history of facial and lower-limb edema, two-year history of left ventricular hypertrophy and sinus bradycardia, and recurring numbness and pain in three lateral digits with bilateral thenar muscle atrophy. Renal biopsy revealed concurrent FD (confirmed via an alpha-galactosidase A enzyme assay, Lyso-GL-3 quantification, and GLA gene sequencing) and IgAN. Heterozygous mutations in the TTN (c.30,484 C > A;p.P10162T) and BAG3 (c.88 A > G;p.I30V) genes were observed. The patient reported that two of her brothers had undergone kidney transplantation; one died suddenly at 60 years of age, and the other required a cardiac pacemaker. The 35-year-old son of the patient was screened for the GLA gene mutation and found to be positive for the same mutation as the patient. The patient was administered oral losartan (50 mg/day). Enzyme replacement therapy was refused due to financial reasons. Her renal and cardiac functions were stable yet worth closely monitoring during follow-up. CONCLUSION The family history of patients with concurrent heart and renal diseases should be assessed in detail. Genetic testing and histological examinations are essential for diagnosing FD with IgAN.

[PMID: 37388940 PMCID: PMC10300636 DOI: 10.3389/fgene.2023.1150822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Accepted: 05/30/2023] [Indexed: 07/01/2023] Open
Abstract
Background: Fabry disease (FD) is a rare X-linked lysosomal storage disease caused by mutations in the GLA gene that encodes α-galactosidase A (α-GAL). Clinical phenotypes tend to vary in monozygotic female twins because mutations are located on the X-chromosome, whereas similar phenotypes are found in male monozygotic twins. Here we report the case of male monozygotic twins with FD presenting with distinguishable renal phenotypes. Case: A 49-year-old male patient who visited the hospital with proteinuria 14 years prior was readmitted for the same issue. His monozygotic twin brother had started hemodialysis 6 months prior due to renal failure of unknown origin. The patient's renal function was within the normal range, while his spot urine protein-to-creatinine ratio was 557 mg/g. Echocardiography revealed left ventricular hypertrophy (LVH). The findings of a renal biopsy were consistent with FD. Genetic testing identified a c.656T>C mutation in the GLA gene, and α-GAL activity was significantly decreased. Genetic screening of his family clarified that his mother, older sister, twin brother, and his daughter had the same genetic mutations. The patient received enzyme replacement therapy 34 times. Subsequently, migalastat was initiated that continues today. Renal function and proteinuria remain stable, and the LVH has mildly improved. Conclusion: This is the first case of male monozygotic twins expressing different progressions of FD. Our findings demonstrate the possibility that environmental or epigenetic factors may critically influence genotype-phenotype discordance.

Abstract
BACKGROUND Enzyme replacement therapy (ERT) with recombinant human α-galactosidase has been available for the treatment of Fabry disease since 2001 in Europe and 2003 in the USA. Treatment outcomes with ERT are dependent on baseline patient characteristics, and published data are derived from heterogeneous study populations. METHODS We conducted a comprehensive systematic literature review of all original articles on ERT in the treatment of Fabry disease published up until January 2017. This article presents the findings in adult male patients. RESULTS Clinical evidence for the efficacy of ERT in adult male patients was available from 166 publications including 36 clinical trial publications. ERT significantly decreases globotriaosylceramide levels in plasma, urine, and in different kidney, heart, and skin cell types, slows the decline in estimated glomerular filtration rate, and reduces/stabilizes left ventricular mass and cardiac wall thickness. ERT also improves nervous system, gastrointestinal, pain, and quality of life outcomes. CONCLUSIONS ERT is a disease-specific treatment for patients with Fabry disease that may provide clinical benefits on several outcomes and organ systems. Better outcomes may be observed when treatment is started at an early age prior to the development of organ damage such as chronic kidney disease or cardiac fibrosis. Consolidated evidence suggests a dose effect. Data described in male patients, together with female and paediatric data, informs clinical practice and therapeutic goals for individualized treatment.

Characterization of a chemically modified plant cell culture expressed human α-Galactosidase-A enzyme for treatment of Fabry disease. Mol Genet Metab 2015; 114:259-67. [PMID: 25155442 DOI: 10.1016/j.ymgme.2014.08.002] [Citation(s) in RCA: 77] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2014] [Revised: 08/05/2014] [Accepted: 08/05/2014] [Indexed: 01/08/2023]
Abstract
Fabry disease is an X-linked recessive disorder caused by the loss of function of the lysosomal enzyme α-Galactosidase-A. Although two enzyme replacement therapies (ERTs) are commercially available, they may not effectively reverse some of the Fabry pathology. PRX-102 is a novel enzyme for the therapy of Fabry disease expressed in a BY2 Tobacco cell culture. PRX-102 is chemically modified, resulting in a cross-linked homo-dimer. We have characterized the in-vitro and in-vivo properties of PRX-102 and compared the results with the two commercially produced α-Galactosidase-A enzymes. Results show that PRX-102 has prolonged in-vitro stability in plasma, after 1h incubation it retains 30% activity compared with complete inactivation of the commercial enzymes. Under lysosomal-like conditions PRX-102 maintains over 80% activity following 10 days of incubation, while commercial enzymes become inactive after 2days. Pharmacokinetic profile of PRX-102 measured in male Fabry mice shows a 10 fold increase in t1/2 in mice (581min) compared to approved drugs. The enzyme has significantly different kinetic parameters to the alternative ERTs available (p-value<0.05, one way ANOVA), although these differences do not indicate any significant biochemical variations. PRX-102 is uptaken to primary human Fabry fibroblasts. The repeat administration of the enzyme to Fabry mice caused significant reduction (p-value<0.05) of Gb3 in various tissues (the measured residual content was 64% in kidney, liver was cleaned, 23% in heart, 5.7% in skin and 16.2% in spleen). PRX-102 has a relatively simple glycosylation pattern, characteristic to plants, having mainly tri-mannose structures with the addition of either α(1-3)-linked fucose or β(1-2)-linked xylose, or both, in addition to various high mannose structures, while agalsidase beta has a mixture of sialylated glycans in addition to high mannose structures. This study concludes that PRX-102 is equivalent in functionality to the current ERTs available, with superior stability and prolonged circulatory half-life. Therefore we propose that PRX-102 is a promising alternative for treatment of Fabry disease.
