Juvenile mucopolysaccharidosis plus disease caused by a missense mutation in VPS33A

Human Mutation, Volume 43, Issue 12, Page 2265-2278, December 2022., 2022
Abstract A rare and fatal disease resembling mucopolysaccharidosis in infants, is caused by impaired intracellular endocytic trafficking due to deficiency of core components of the intracellular membrane‐tethering protein complexes, HOPS, and CORVET. Whole exome sequencing identified a novel VPS33A mutation in a patient suffering from a variant form of

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.

O-GlcNAcase:promiscuous hexosaminidase or key regulator of O-GlcNAc signalling? [PDF]

, 2014
O-GlcNAc signaling is regulated by an opposing pair of enzymes: O-GlcNAc transferase installs and O-GlcNAcase (OGA) removes the modification from proteins.

A single site in human β-hexosaminidase A binds both 6-sulfate-groups on hexosamines and the sialic acid moiety of GM2 ganglioside [PDF]

, 2003
Human β-hexosaminidase A (Hex A) (αβ) is composed of two subunits whose primary structures are ∼60% identical. Deficiency of either subunit results in severe neurological disease due to the storage of GM2 ganglioside; Tay–Sachs disease, α deficiency, and

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.

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.

Genotype-phenotype correlation of gangliosidosis mutations using in silico tools and homology modeling

Molecular Genetics and Metabolism Reports, 2019
Gangliosidoses, including GM1-gangliosidosis and GM2-gangliosidosis (Tay-Sachs disease and Sandhoff disease), are lysosomal disorders resulting from enzyme deficiencies and accumulation of gangliosides.
