From Molecule to Meaning: Neuronopathic Biomarkers and Clinical Relevance in GM1. [PDF]

J Inherit Metab Dis
ABSTRACT GM1 gangliosidosis is a rare, progressively neurodegenerative lysosomal storage disorder characterized by profound central nervous system involvement and substantial clinical heterogeneity. The development of reliable biomarkers is essential for tracking disease progression, stratifying patients, and advancing clinical trial readiness. Primary

Novel HEXA variants in Korean children with Tay–Sachs disease with regression of neurodevelopment from infancy

Molecular Genetics &Genomic Medicine, Volume 9, Issue 6, June 2021., 2021
We present three independent Korean children with typical clinical manifestations and neurodevelopmental regression at around 8 months of age, who were biochemically and molecularly confirmed as an infantile form of TSD. Fundus examination can be helpful for early diagnosis of children with neurodevelopmental regression.

Assessment of Target Engagement in a First‐in‐Human Trial with Sinbaglustat, an Iminosugar to Treat Lysosomal Storage Disorders

Clinical and Translational Science, Volume 14, Issue 2, Page 558-567, March 2021., 2021
In this first‐in‐human study, the tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple oral doses of sinbaglustat, a dual inhibitor of glucosylceramide synthase (GCS) and non‐lysosomal glucosyl ceramidase (GBA2), were investigated in healthy subjects.

The juvenile gangliosidoses: A timeline of clinical change

Molecular Genetics and Metabolism Reports, 2020
Background: The gangliosidoses are rare inherited diseases that result in pathologic accumulation of gangliosides in the central nervous system and other tissues, leading to severe and progressive neurological impairment and early death in the childhood ...

Cerebral organoids derived from Sandhoff disease-induced pluripotent stem cells exhibit impaired neurodifferentiation[S]

Journal of Lipid Research, 2018
Sandhoff disease, one of the GM2 gangliosidoses, is a lysosomal storage disorder characterized by the absence of β-hexosaminidase A and B activity and the concomitant lysosomal accumulation of its substrate, GM2 ganglioside.

Efficacy of a Bicistronic Vector for Correction of Sandhoff Disease in a Mouse Model

Molecular Therapy: Methods & Clinical Development, 2019
GM2 gangliosidoses are a family of severe neurodegenerative disorders resulting from a deficiency in the β-hexosaminidase A enzyme. These disorders include Tay-Sachs disease and Sandhoff disease, caused by mutations in the HEXA gene and HEXB gene ...

Lysosphingolipid Quantitation in Plasma and Dried-Blood Spots Using Targeted High-Resolution Mass Spectrometry. [PDF]

J Clin Lab Anal
Sphingolipidoses is a group of rare inherited lysosomal diseases that require an early and accurate diagnosis for effective treatment and patient management. A high‐resolution mass spectrometry method coupled with liquid chromatography has beendeveloped to analyze lysosphingolipids in plasma and dried blood spots.

Bis(monoacylglycero)phosphate: a secondary storage lipid in the gangliosidoses

Journal of Lipid Research, 2015
Bis(monoacylglycero)phosphate (BMP) is a negatively charged glycerophospholipid with an unusual sn-1;sn-1′ structural configuration. BMP is primarily enriched in endosomal/lysosomal membranes.

From amaurotic idiocy to biochemically defined lipid storage diseases: the first identification of GM1-Gangliosidosis [PDF]

, 2023
On February 23rd 1936, a boy-child (“Kn”) died in an asylum near Munich after years of severe congenital dis-ease, which had profoundly impaired his development leading to inability to walk, talk and see as well as to severe epilepsy.

Critical role of iron in the pathogenesis of the murine gangliosidoses

Neurobiology of Disease, 2009
Neurodegeneration is a prominent feature of the gangliosidoses, a group of lysosomal storage diseases. Here we show altered iron homeostasis in mouse models of both GM1 and GM2 gangliosidoses, which are characterized by progressive depletion of iron in ...
