Generation of mice with combined Hexa Gly269Ser KI or KO and Neu3 KO alleles to create new models of GM2 gangliosidoses [PDF]

Biology Open
The GM2 gangliosidoses are lysosomal storage disorders exhibiting a spectrum of neurological phenotypes ranging from childhood death to debilitating adult-onset neurological impairment. To date, no mouse model harbouring a specific human mutation causing

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 ...

Optimization of Enzyme Essays to Enhance Reliability of Activity Measurements in Leukocyte Lysates for the Diagnosis of Metachromatic Leukodystrophy and Gangliosidoses

Cells, 2020
(1) Lysosomal storage diseases are rare inherited disorders with no standardized or commercially available tests for biochemical diagnosis. We present factors influencing the quality of enzyme assays for metachromatic leukodystrophy (MLD) and ...

L-Arginine Ameliorates Defective Autophagy in GM2 Gangliosidoses by mTOR Modulation

Cells, 2021
Aims: Tay–Sachs and Sandhoff diseases (GM2 gangliosidosis) are autosomal recessive disorders of lysosomal function that cause progressive neurodegeneration in infants and young children. Impaired hydrolysis catalysed by β-hexosaminidase A (HexA) leads to

Lysosomal storage diseases. Sphingolipidoses — gangliosidoses

Pediatrician (St. Petersburg), 2023
Epidemiology, clinical, biochemical and molecular genetic characteristics of gangliosidoses, genetically heterogeneous group of autosomal recessive diseases caused by hereditary deficiency of lysosomal glycohydrolases involved in the catabolism of GM1-, GM2- and GA2-gangliosides, are presented.

Functionality of a bicistronic construction containing HEXA and HEXB genes encoding β-hexosaminidase A for cell-mediated therapy of GM2 gangliosidoses

Neural Regeneration Research, 2022
Tay-Sachs disease and Sandhoff disease are severe hereditary neurodegenerative disorders caused by a deficiency of β-hexosaminidase A (HexA) enzyme, which results in the accumulation of GM2 gangliosides in the nervous system cells.

A master protocol to investigate a novel therapy acetyl-l-leucine for three ultra-rare neurodegenerative diseases: Niemann-Pick type C, the GM2 gangliosidoses, and ataxia telangiectasia

Trials, 2021
Background The lack of approved treatments for the majority of rare diseases is reflective of the unique challenges of orphan drug development. Novel methodologies, including new functionally relevant endpoints, are needed to render the development ...

Increased phosphorylation of HexM improves lysosomal uptake and potential for managing GM2 gangliosidoses

BBA Advances, 2022
Tay-Sachs and Sandhoff diseases are genetic disorders resulting from mutations in HEXA or HEXB, which code for the α- and β-subunits of the heterodimer β-hexosaminidase A (HexA), respectively.

Intracerebroventricular administration of a modified hexosaminidase ameliorates late-stage neurodegeneration in a GM2 mouse model. [PDF]

PLoS ONE
The GM2 gangliosidoses, Tay-Sachs disease and Sandhoff disease, are devastating neurodegenerative disorders caused by β-hexosaminidase A (HexA) deficiency.

Natural history study of glycan accumulation in large animal models of GM2 gangliosidoses.

PLoS ONE, 2020
β-hexosaminidase is an enzyme responsible for the degradation of gangliosides, glycans, and other glycoconjugates containing β-linked hexosamines that enter the lysosome. GM2 gangliosidoses, such as Tay-Sachs and Sandhoff, are lysosomal storage disorders
