1 gene identificado com associação a esta condição. Padrão de herança: Autosomal recessive.
Hydrolyzes the non-reducing end N-acetyl-D-hexosamine and/or sulfated N-acetyl-D-hexosamine of glycoconjugates, such as the oligosaccharide moieties from proteins and neutral glycolipids, or from certain mucopolysaccharides (PubMed:11707436, PubMed:8123671, PubMed:8672428, PubMed:9694901). The isozyme B does not hydrolyze each of these substrates, however hydrolyzes efficiently neutral oligosaccharide (PubMed:11707436). Only the isozyme A is responsible for the degradation of GM2 gangliosides in
LysosomeCytoplasmic vesicle, secretory vesicle, Cortical granule
GM2-gangliosidosis 2
An autosomal recessive lysosomal storage disease marked by the accumulation of GM2 gangliosides in the neuronal cells. Clinically indistinguishable from GM2-gangliosidosis type 1, presenting startle reactions, early blindness, progressive motor and mental deterioration, macrocephaly and cherry-red spots on the macula.

Generation and characterization of induced pluripotent stem cell (iPSC) lines from patients affected with Tay-Sachs and Sandhoff disease.
Tay-Sachs and Sandhoff diseases, are sphingolipidoses caused by rare genetic mutations in the HEXA and HEXB genes, that encode the alpha and beta subunits of lysosomal hexosaminidase, respectively. Here, we report the generation and characterization of three Tay-Sachs and one Sandhoff iPSC lines derived from patients with late-onset disease carrying mutations at the HEXA or HEXB gene. The Tay-Sachs patients carried either homozygous or complex heterozygous mutations in the HEXA gene. The Sandhoff patient carried a heterozygous mutation in the HEXB gene. These four iPSC lines will serve as a valuable resource for the development of in vitro lysosomal storage disease models and therapeutic drug development.
Therapeutic Effects of Nizubaglustat in a Mouse Model of GM2 Gangliosidosis.
Nizubaglustat is a novel selective inhibitor of glucosylceramide synthase (GCS) and the non-lysosomal glucocerebrosidase (NLGase, GbA2) with brain penetrant properties. It is currently in clinical development as an oral treatment for rare lysosomal storage diseases with neurological involvement. One such disease group called GM2 gangliosidosis, to date, has no approved therapeutic treatment. To test the potential efficacy of nizubaglustat in a mouse model of GM2 gangliosidoses, we treated Sandhoff disease (SD) mice carrying a homozygous null mutation in the Hexb gene, as well as healthy heterozygous controls, to understand exposure versus effect under disease conditions. Oral doses of nizubaglustat from 0.2 to 6 mg/kg/day showed linear pharmacokinetics with plasma and brain concentrations sufficient to drive pharmacodynamic changes in markers of target engagement and efficacy. In the brain, an approximately 10-fold increase in GlcCer C16:0 and C18:0 was observed, which is consistent with NLGase inhibition. A statistically significant increase in survival (22%) was noted in SD mice treated at doses as low as 0.2 mg/kg/day compared to controls. Behavioral analyses, which included rotarod and open field tests, were also significantly improved. To understand the added potential mechanism of the improved survival, a subset of neuroinflammatory markers was also examined in specific brain regions. Gene expression studies showed an anti-inflammatory pattern with downregulation of Itgax, Trem2, Cxcl10 genes as an example. Brain immunohistochemistry for GFAP was decreased compared to vehicle treated control animals. These results provide proof-of-concept that nizubaglustat can be a promising therapeutic drug to treat patients with GM2 gangliosidoses.
Venglustat in GM2 gangliosidoses and related disorders: Results of the AMETHIST randomized controlled and basket trials.
To evaluate efficacy and safety of venglustat for GM2 gangliosidoses (Tay-Sachs and Sandhoff diseases) and cognate diseases. The AMETHIST phase 3, randomized, double-blind, placebo-controlled study evaluated oral venglustat (N = 40) vs placebo (N = 19) in adults with late-onset GM2 gangliosidoses. Coprimary endpoints were annual percent change on the 9-Hole Peg Test and percent change in cerebrospinal fluid (CSF) GM2 ganglioside from baseline to week 104. A secondary population of participants with cognate diseases (N = 16) received open-label venglustat in a "basket" trial. CSF GM2 decreased by 47.6% (90% CI: -52.6, -42.6) with venglustat versus 11.3% (90% CI: -18.3, -4.4) with placebo (difference: -36.2 [90% CI: -44.8, -27.7], P < .0001). The annual percent change in 9-Hole Peg Test was 2.49% (90% CI: 0.28, 4.74) with venglustat versus 0.95% (90% CI: -2.16, 4.15) with placebo (difference: 1.54% [90% CI: -2.33, 5.39], P = .74). Decreased CSF GM2 concentrations did not correlate with clinical endpoints. Secondary population participants remained clinically stable. The most common adverse events were fall, headache, and contusion with placebo and fall, and COVID-19 and headache with venglustat. In adults with late-onset GM2 gangliosidoses, oral venglustat decreased CSF GM2 concentrations but without clinical improvement in the endpoints assessed. No new safety findings were observed.
Bilateral Macular Cherry-Red Spots in Infantile Sandhoff Disease.
Genetic Modeling of Lysosomal Storage Disorders (LSDs) in the Brain-Midgut Axis of Drosophila melanogaster During Aging.
Lysosomal storage disorders (LSDs) are a group of rare inherited diseases caused by mutations in the genes encoding the proteins involved in normal lysosomal functions, leading to an accumulation of undegraded substrates within lysosomes. Among the most prominent clinical features are neurological impairment and neurodegeneration, arising from widespread cellular dysfunction. The development of powerful and reliable animal model systems that can in vivo recapitulate human LSD pathologies is critical for understanding disease mechanisms and advancing therapeutic strategies. In this study, we identified the Drosophila melanogaster orthologs of human LSD-related genes using the DIOPT tool and performed tissue-specific gene silencing along the brain-midgut axis via the use of GAL4/UAS and RNAi combined technologies. Transgenic fly models presented key features of human LSD pathologies, including significantly shortened lifespans and a progressive locomotor decline that serves as a measure for neuromuscular disintegration, following age- and sex-dependent patterns. These phenotypic parallels in pathology strongly support the functional relevance of the selected orthologs and underscore the value of Drosophila as a versatile in vivo model system for advanced LSD pathology research, offering state-of-the-art genetic tools for molecularly dissecting disease mechanisms and providing cutting-edge novel platforms for high-throughput genetic and/or pharmacological screening, moving towards development of new therapeutically beneficial drug-based regimens and mutant gene-rescue schemes.
