Characterization of inducible models of Tay-Sachs and related disease. [PDF]

PLoS Genetics, 2012
Tay-Sachs and Sandhoff diseases are lethal inborn errors of acid β-N-acetylhexosaminidase activity, characterized by lysosomal storage of GM2 ganglioside and related glycoconjugates in the nervous system.

Diagnostic Dilemma in an Infant With Sound-Triggered Motor Events: Reflex Epilepsy Versus Exaggerated Startle-A Case Report. [PDF]

Clin Case Rep
ABSTRACT Auditory‐triggered motor events in infancy present a significant diagnostic challenge due to overlap between epileptic and non‐epileptic startle phenomena. We report the case of a term female infant with neonatal‐onset seizures and subsequent development of reproducible sound‐triggered jerky movements, raising diagnostic uncertainty between ...

Alkaline Phosphatase and Infantile GM1 Gangliosidosis: A Simple Biomarker for a Complex Disease? [PDF]

JIMD Rep
ABSTRACT GM1 gangliosidosis is a lysosomal storage disease (LSD) caused by β‐galactosidase deficiency, characterized by the accumulation of gangliosides in various tissues. Among different GM1 forms (infantile form, late‐infantile and juvenile form, and late‐onset form), the infantile form is the most severe: despite an early clinical onset with rapid ...

Magnetic resonance findings of the corpus callosum in canine and feline lysosomal storage diseases.

PLoS ONE, 2013
Several reports have described magnetic resonance (MR) findings in canine and feline lysosomal storage diseases such as gangliosidoses and neuronal ceroid lipofuscinosis.

GM2 ganglioside accumulation causes neuroinflammation and behavioral alterations in a mouse model of early onset Tay-Sachs disease

Journal of Neuroinflammation, 2020
Background Tay-Sachs disease (TSD), a type of GM2-gangliosidosis, is a progressive neurodegenerative lysosomal storage disorder caused by mutations in the α subunit of the lysosomal β-hexosaminidase enzyme.

Membrane lipids and their degradation compounds control GM2 catabolism at intralysosomal luminal vesicles

Journal of Lipid Research, 2019
The catabolism of ganglioside GM2 is dependent on three gene products. Mutations in any of these genes result in a different type of GM2 gangliosidosis (Tay-Sachs disease, Sandhoff disease, and the B1 and AB variants of GM2 gangliosidosis), with GM2 as ...

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

A case of spastic paraplegia type 11 mimicking a GM2-gangliosidosis

, 2022
Introduction Spastic paraplegia type 11 (SPG11) is the most frequent autosomal recessive HSP. Studies on SPG11 patients' fibroblasts, post-mortem brains, and mouse models revealed endolysosomal system dysfunction and lipid accumulation, especially ...

In cellulo examination of a beta-alpha hybrid construct of beta-hexosaminidase A subunits, reported to interact with the GM2 activator protein and hydrolyze GM2 ganglioside. [PDF]

PLoS ONE, 2013
The hydrolysis in lysosomes of GM2 ganglioside to GM3 ganglioside requires the correct synthesis, intracellular assembly and transport of three separate gene products; i.e., the alpha and beta subunits of heterodimeric beta-hexosaminidase A, E.C. # 3.2.1.

Characterization of Human Recombinant β1,4-GalNAc-Transferase B4GALNT1 and Inhibition by Selected Compounds

Molecules
Gangliosides are essential for membrane functions, cell recognition, and maintenance of the nervous system. GM2 gangliosidosis is a group of rare genetic lysosomal storage diseases that includes Tay-Sachs disease (TSD), Sandhoff disease (SD), and AB ...
