Precision medicine in Fabry disease.

Nephrol Dial Transplant 2021 Jun;36(Supplement_2):14-23

Internal Medicine D, Department of Nephrology, Hypertension and Rheumatology, Interdisciplinary Fabry Center Münster, University Hospital Münster, Münster, Germany.

Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by mutations in the α-galactosidase A (GLA) gene, leading to a deficiency in α-galactosidase A. The lysosomal accumulation of glycosphingolipids, primarily globotriaosylceramide (Gb3) and its deacylated form, globotriaosylsphingosine (lyso-Gb3), results in progressive renal failure, cardiomyopathy associated with cardiac arrhythmia and recurrent cerebrovascular events, significantly limiting life expectancy in affected patients. In male patients, a definitive diagnosis of FD involves demonstrating a GLA deficiency in leucocytes. Read More

Neurodegenerative Disease Risk in Carriers of Autosomal Recessive Disease.

Front Neurol 2021 4;12:679927. Epub 2021 Jun 4.

Department of Clinical and Movement Neurosciences, University College London, Queen Square Institute of Neurology, London, United Kingdom.

Genetics has driven significant discoveries in the field of neurodegenerative diseases (NDDs). An emerging theme in neurodegeneration warrants an urgent and comprehensive update: that carrier status of early-onset autosomal recessive (AR) disease, typically considered benign, is associated with an increased risk of a spectrum of late-onset NDDs. () gene mutations, responsible for the AR lysosomal storage disorder Gaucher disease, are a prominent example of this principle, having been identified as an important genetic risk factor for Parkinson disease.

Gaucher disease: Identification and novel variants in Mexican and Spanish patients.

Arch Med Res 2021 Jun 13. Epub 2021 Jun 13.

Unidad de Investigación Médica en Inmunología, Hospital de Pediatría, CMN-SXXI, IMSS, Ciudad de México, Méx. Electronic address:

Background: Gaucher disease (GD) is the most prevalent lysosomal storage disorder, affecting all ethnic groups, although its prevalence is higher in Ashkenazi Jewish populations. Three clinical forms of GD have been described: Type 1 non-neuronopathic, type 2 acute neuronopathic, and type 3 subacute neuronopathic. An autosomal recessive disorder is caused by variants in the human glucocerebrosidase gene (GBA; MIM*606463) located on chromosome 1q21, resulting from deficit or lack of activity of the β-glucocerebrosidase enzyme, leading to the accumulation of glucocerebroside substrate in the cells of the macrophage-monocyte system.

Inborn Errors of Metabolism Associated With Autism Spectrum Disorders: Approaches to Intervention.

Front Neurosci 2021 28;15:673600. Epub 2021 May 28.

Department of Paediatrics, University Hospital Center Zagreb and University of Zagreb School of Medicine, Zagreb, Croatia.

Increasing evidence suggests that the autism spectrum disorder (ASD) may be associated with inborn errors of metabolism, such as disorders of amino acid metabolism and transport [phenylketonuria, homocystinuria, S-adenosylhomocysteine hydrolase deficiency, branched-chain α-keto acid dehydrogenase kinase deficiency, urea cycle disorders (UCD), Hartnup disease], organic acidurias (propionic aciduria, L-2 hydroxyglutaric aciduria), cholesterol biosynthesis defects (Smith-Lemli-Opitz syndrome), mitochondrial disorders (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes-MELAS syndrome), neurotransmitter disorders (succinic semialdehyde dehydrogenase deficiency), disorders of purine metabolism [adenylosuccinate lyase (ADSL) deficiency, Lesch-Nyhan syndrome], cerebral creatine deficiency syndromes (CCDSs), disorders of folate transport and metabolism (cerebral folate deficiency, methylenetetrahydrofolate reductase deficiency), lysosomal storage disorders [Sanfilippo syndrome, neuronal ceroid lipofuscinoses (NCL), Niemann-Pick disease type C], cerebrotendinous xanthomatosis (CTX), disorders of copper metabolism (Wilson disease), disorders of haem biosynthesis [acute intermittent porphyria (AIP)] and brain iron accumulation diseases. In this review, we briefly describe etiology, clinical presentation, and therapeutic principles, if they exist, for these conditions. Additionally, we suggest the primary and elective laboratory work-up for their successful early diagnosis. Read More

Orv Hetil 2021 06 13;162(24):938-942. Epub 2021 Jun 13.

1 Semmelweis Egyetem, Általános Orvostudományi Kar, Bőr-, Nemikórtani és Dermatoonkológiai Klinika, Primer Immundeficiencia Klinikai Egység és Laboratórium, Budapest, Mária u. 41., 1085.

At the start of the pandemic caused by the novel coronavirus (SARS-CoV-2), the Gaucher disease community anticipated that infection with this emerging viral pathogen would be associated with high morbidity and mortality in individuals with this chronic metabolic disorder. Surprisingly, however, preliminary studies suggest that Gaucher disease does not confer a higher risk of severe, life-threatening effects of SARS-CoV-2 infection, and no severe cases have been reported in large cohorts of patients from the United States, Europe and Israel. It is thought that the accumulation of glucocerebroside in the cells of Gaucher patients may promote immune tolerance rather than inflammation on exposure to SARS-CoV-2. Read More

Department of Veterinary Science, University of Parma, Via Taglio, 8, 43100 Parma, Italy.

Gangliosidoses are inherited lysosomal storage disorders caused by reduced or absent activity of either a lysosomal enzyme involved in ganglioside catabolism, or an activator protein required for the proper activity of a ganglioside hydrolase, which results in the intra-lysosomal accumulation of undegraded metabolites. We hereby describe morphological, ultrastructural, biochemical and genetic features of GM2 gangliosidosis in three captive bred wild boar littermates. The piglets were kept in a partially-free range farm and presented progressive neurological signs, starting at 6 months of age. Read More

Altered heparan sulfate metabolism during development triggers dopamine-dependent autistic-behaviours in models of lysosomal storage disorders.

Nat Commun 2021 06 9;12(1):3495. Epub 2021 Jun 9.

Telethon Institute of Genetics and Medicine, Pozzuoli, Naples, Italy.

Lysosomal storage disorders characterized by altered metabolism of heparan sulfate, including Mucopolysaccharidosis (MPS) III and MPS-II, exhibit lysosomal dysfunctions leading to neurodegeneration and dementia in children. In lysosomal storage disorders, dementia is preceded by severe and therapy-resistant autistic-like symptoms of unknown cause. Using mouse and cellular models of MPS-IIIA, we discovered that autistic-like behaviours are due to increased proliferation of mesencephalic dopamine neurons originating during embryogenesis, which is not due to lysosomal dysfunction, but to altered HS function.

Decreased glucocerebrosidase activity and substrate accumulation of glycosphingolipids in a novel GBA1 D409V knock-in mouse model.

PLoS One 2021 9;16(6):e0252325. Epub 2021 Jun 9.

The Michael J. Fox Foundation for Parkinson's Research, Grand Central Station, New York, New York, United States of America.

Multiple mutations have been described in the human GBA1 gene, which encodes the lysosomal enzyme beta-glucocerebrosidase (GCase) that degrades glucosylceramide and is pivotal in glycosphingolipid substrate metabolism. Depletion of GCase, typically by homozygous mutations in GBA1, is linked to the lysosomal storage disorder Gaucher's disease (GD) and distinct or heterozygous mutations in GBA1 are associated with increased Parkinson's disease (PD) risk. While numerous genes have been linked to heritable PD, GBA1 mutations in aggregate are the single greatest risk factor for development of idiopathic PD. Read More
