Abstract
Fabry disease (FD) is an X-linked lysosomal storage disease caused by pathogenic variants in the GLA gene. It has a wide range of clinical manifestations, typically related to the specific underlying GLA variant. One of the main features of FD is kidney involvement; therefore, several studies have addressed the prevalence of FD in all types of patients with chronic kidney disease. We performed a systematic review and meta-analysis of screening studies in chronic kidney disease patients, including those on dialysis, had undergone a kidney transplantation, and those who did not receive kidney replacement therapy, and assessed the prevalence of pathogenic variants in these cohorts. Fifty-five studies were included, involving a total of 84,062 individuals. Of these, 251 cases were positive for FD; a third of the reported GLA variants were of a benign phenotype (37.8%), followed by classical phenotype (31.7%), late onset (15.5%), and of uncertain significance (14.7%). The overall prevalence among dialysis patients was 0.10% (CI95%, 0.06-0.15), 0.28% (CI95%, 0.06-0.15) among patients with kidney transplantation, and 0.17% (CI95%, 0.11-0.39) among those without kidney replacement therapy. Although the overall prevalence of FD is low in patients with kidney involvement, screening, especially in patients who have not yet undergone kidney replacement therapy, is important, in order to provide timely and effective treatment interventions, including disease modifying therapies. The prevalence of kidney involvement in females with Fabry Disease is lower but this should not lead to inadequate follow up. Further research is also needed on the impact of genetic variants of uncertain significance to elucidate their role in Fabry disease.

Hołub T, Kędzierska K, Muras-Szwedziak K, Nowicki M. Serum neurofilament light chain is not a useful biomarker of central nervous system involvement in women with Fabry disease. Intractable Rare Dis Res 2021; 10:276-282. [PMID: 34877240 PMCID: PMC8630462 DOI: 10.5582/irdr.2021.01115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 10/27/2021] [Accepted: 11/02/2021] [Indexed: 11/05/2022] Open
Abstract
Neurofilament Light Chain (NfL) serum concentration is a new noninvasive marker of neurodegenerative disorders. Fabry disease (FD) leads to accumulation of glycosphingolipids in tissues leading to progressive damage of critical body systems and organs, including peripheral and central nervous system. There are no established serum markers of neurodegeneration in FD. Our cross-sectional single-center study was designed to prove the concept that serum NfL levels could reflect the severity of cognitive impairment and indirectly, the level of central nervous system involvement in women at earlier stages of FD. Twelve women with a diagnosis of FD confirmed by genetic tests and 12 matched healthy subjects were included. Serum concentrations of NfL were measured in all subjects together with neuropsychological tests that included Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA). Quality of life was assessed with the Short Form Survey (SF-36). FD patients and healthy subjects did not differ with respect to serum NfL concentration, results of neuropsychological tests and quality of life. There was a significant positive correlation between NfL and globotriaosylosphingosine (lyso-Gb3) concentration in women with FD (R = 0,69, p = 0.01). There was also a correlation between NfL concentration and MoCA score but not MMSE score. Receiver operating characteristic (ROC) analysis showed that the best predictor for Mild Cognitive Impairment in both groups was eGFR. Serum NfL concentration does not appear to predict the degree of nervous system involvement in women with FD.

Abstract
Introduction: Fabry disease is a chronic, progressive, and multi-system hereditary condition, related to an Xq22 mutation in X chromosome, which results in deficiency of alpha-galactosidase enzyme, hence reduced capacity of globotriaosylceramide degradation. Objectives: to evaluate the prevalence of Fabry disease (FD) mutations, as well as its signs and symptoms, among relatives of chronic kidney disease (CKD) patients diagnosed with FD during a previously conducted study, named “Clinical and epidemiological analysis of Fabry disease in dialysis centers in Brazil”. Methods: a cross-sectional study was carried out, and data was collected by interviewing the relatives of patients enrolled in the Brazil Fabry Kidney Project and blood tests for both Gb3 dosage and genetic testing. Results: Among 1214 interviewed relatives, 115 (9.47%) were diagnosed with FD, with a predominance of women (66.10%). The most prevalent comorbidities were rheumatologic conditions and systemic hypertension (1.7% each), followed by heart, neurological, cerebrovascular diseases, and depression in 0.9% of individuals. Intolerance to physical exercise and tiredness were the most observed symptoms (1.7%), followed by periodic fever, intolerance to heat or cold, diffuse pain, burn sensation or numbness in hands and feet, reduced or absent sweating, as well as abdominal pain after meals in 0.9%. Conclusion: We found a prevalence of Fabry disease in 9.47% of relatives of CKD patients with this condition, remarkably with a 66.1% predominance of women, which contrasts with previous reports. The screening of family members of FD patients is important, since it can lead to early diagnosis and treatment, thus allowing better quality of life and improved clinical outcomes for these individuals.

Abstract
Fabry disease (FD) is a rare X chromosomally transmitted lysosomal storage disorders with an absence or deficiency of the enzyme alpha-galactosidase. The deposition of globotriaosylceramide (Gb3) may cause damage to all organs, particularly brain, heart and kidney. While acroparaesthesia, hypo- or anhydrosis and diarrhoea are the main symptoms in childhood, cardiac involvement with left ventricular hypertrophy (LVH), renal insufficiency, diffuse pain attacks and apoplexy are the main symptoms in adulthood. Regular examinations are necessary to record organ involvement and its progression. A major challenge is therefore to make a diagnosis at an early disease stage. This is the only way that treatment can be started if there is an indication. If FD is suspected, alpha-galactosidase should be tested in male patients and genetic testing should be performed in females to confirm the diagnosis. Since 2001, enzyme replacement therapy (ERT) has been available as a causal therapy. In 2016, chaperone therapy with the drug Migalastat was approved in the European Union, which leads to stabilisation of the defective alpha-galactosidase. Studies on gene therapy to cure FD in phase I/II. This review summarizes which patient should be screened, how to confirm the diagnosis and which examinations should be performed in FD patients during the course of the disease.

Abstract
Fabry disease (FD) is a treatable X linked lysosomal storage disorder with a wide phenotypic spectrum. There is a scarcity of published data on the burden of FD in India. This study evaluates the clinical and molecular spectrum of Indian patients with FD. In this multicentric study involving 10 tertiary referral centers in India, we analyzed the clinical course and genotype of 54 patients from 37 families. Family screening identified 19 new patients (35%) from 12 index cases. Then, 33 GLA gene variants were identified in 49/54 (90.7%) which included 11 novel and 22 known pathogenic variants. Of the 54 patients in our cohort, 40 patients had "classical" and 10 patients had a "nonclassical" presentation. The symptoms and signs included kidney dysfunction in 38/54 (70.3%), neuropathic pain in 34/54 (62.9%), left ventricular hypertrophy in 22/49 (44.8%) and stroke in 5/54 (9.2%). Female heterozygotes were 10/54 (18.5%) of whom 2 were index cases. There was a significant delay in reaching the diagnosis of 11.7 years. Enzyme replacement therapy was initiated in 28/54 (51.8%) patients with significant improvement of neuropathic pain and gastrointestinal symptoms. This study highlights the clinical presentation and mutational spectrum of FD in India and suggests that family screening and screening of high-risk groups (hypertrophic cardiomyopathy, idiopathic chronic renal failure and cryptogenic stroke) could be the most cost-effective strategies for early identification of FD.

Abstract
Fabry disease (FD) is an X-linked lysosomal storage disorder caused by absence or deficient activity of α-galactosidase A (α-Gal A) due to mutations in the α-galactosidase A gene (GLA), leading to progressive accumulation of globotriaosylceramide (Gb3) in tissues and organs including heart, kidney, the eyes, vascular endothelium, the nervous system and the skin. Cardiac involvement is leading to fatal complications and reduced life expectancy. FD is treatable with disease-specific treatment (enzyme replacement therapy (ERT) or with chaperone therapy). Therefore, the early diagnosis of FD is crucial for reducing the morbidity and mortality. Screening of high-risk populations (eg, patients with unexplained left ventricular hypertrophy (LVH), young patients with unexplained stroke, and patients with unexplained renal failure proteinuria or microalbuminuria) yields good results. The diagnostic algorithm is gender-specific. Initially, the measurement of α-Gal A activity is recommended in males, and optionally in females. In males with non-diagnostic residual activity (5–10%) activity, genetic testing is afterwards done for confirming the diagnosis. In fact, diagnosis of FD is not possible without genetic testing for both males and females. Globotriaosysphingosine (lyso-Gb3) for identification of atypical FD variants and high- sensitive troponin T (hsTNT) for identification of cardiac involvement are also important diagnostic biomarkers. The aim of this review was to provide an update on diagnosis and screening of patients with FD.

Identifying Fabry patients in dialysis population: prevalence of GLA mutations by renal clinic screening, 1995-2019. J Nephrol 2019; 33:569-581. [PMID: 31650418 DOI: 10.1007/s40620-019-00663-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Accepted: 10/15/2019] [Indexed: 01/28/2023]
Abstract
BACKGROUND Fabry disease (FD) is a rare X-linked genetic disorder of glycosphingolipid catabolism caused by mutations in the GLA gene. Its heterogeneous presentation, the paucity of specific early markers, and the absence of a genotype-phenotype correlation are associated with a delayed or missed diagnosis. The true prevalence of FD remains so far unknown. METHODS A systematic search of FD screening studies in dialysis patients published from January 1995 until January 2019 was performed to reanalyze the prevalence of GLA mutations in this population after assigning their correct phenotype. RESULTS Twenty five screening studies involving 39,621 dialysis patients were included. Of them, 116 [91 males (0.23%) and 25 females (0.06%)] were positive to the GLA sequencing analysis. 56 (48.2%) had benign variant, 52 (44.8%) a pathogenic GLA mutation (39 classic and 13 late onset mutations) and 8 (6.9%) a mutation of uncertain significance. The overall prevalence of GLA variants was 0.24% [CI 95%, 0.17-0.32] while the overall prevalence recalculated on basis of only pathogenetic mutations was 0.14% [CI 95%, 0.08-0.20]. This difference was significant (P = 0.048). CONCLUSIONS Although the real prevalence of classic FD is low, the screening in the high-risk renal population remains of primary interest as an early diagnosis is fundamental for a timely specific therapy; moreover, the identification of index cases could allow patients' relatives to be investigated and promptly treated.
