GM2-gangliosidosis 1
An autosomal recessive lysosomal storage disease marked by the accumulation of GM2 gangliosides in the neuronal cells. It is characterized by GM2 gangliosides accumulation in the absence of HEXA activity, leading to neurodegeneration and, in the infantile form, death in early childhood. It exists in several forms: infantile (most common and most severe), juvenile and adult (late-onset).

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.
Intrathecal delivery of AAVrh10-mHexa combined with anti-inflammatory treatment reduces neuropathological markers and extends the lifespan of mice with early-onset Tay-Sachs disease.
Tay-Sachs disease is a lysosomal storage disorder caused by mutations in the HEXA gene, which encodes the α-subunit of β-hexosaminidase A-an enzyme that breaks down GM2 ganglioside. Recently, a mouse model of Tay-Sachs, the DKO, with deficiencies in both Hexa and Neu3 genes, showed severe neurological symptoms and neuroinflammation, surviving up to 20 weeks. In this study, we evaluated the therapeutic potential of intrathecal AAVrh10-mediated delivery of mouse Hexa, in combination with istradefylline treatment, in DKO mice. Using molecular, immunohistochemical, and behavioral methods, we found that the mice's lifespan increased to 30 weeks after receiving AAV alone or with istradefylline. Molecular analyses revealed increased Hexa activity, accompanied by reduced levels of the lysosomal marker Lamp-1 and pro-inflammatory cytokines, such as CCL2 and CCL3, in the cortex, cerebellum, and various organs, including the kidney, liver, and spleen. Immunohistochemistry revealed clearance of GM2 accumulation, fewer lysosomes, decreased active astrocytes, and improvements in neurons and oligodendrocytes in the brains of DKO mice. Correspondingly, their motor activity also improved. These results suggest that AAVrh10-based intrathecal delivery combined with istradefylline provides a promising therapeutic strategy for treating Tay-Sachs disease.
Development of national biobank for lysosomal storage disorders in India- a step towards advancing research and precision medicine.
Lysosomal storage disorders (LSDs) are a diverse group of over 70 rare, inherited metabolic conditions that present significant diagnostic and therapeutic challenges, especially in genetically diverse and resource-limited settings like India. To address the lack of a centralized clinical and genomic data registry for LSDs, we established the first government-supported national LSDs biobank in India. This study describes the infrastructure, sample collection, storage procedures, ethical framework, and expected impact of the biobank on research, diagnostics, and patient care. The study includes biological samples and clinical-genetic data from 530 patients, (526 unrelated individuals and 2 sibling pairs), over a 17-year period (2008-2025). Biological samples including genomic DNA from blood, plasma, and urine precipitate were processed for enzyme and genetic investigations. A centralized webpage has been established to manage the biological sample data including clinical, enzyme and genetic data. The LSD biobank cohort encompasses 8 LSD subgroups across 27 disorders, with the most common being Gaucher disease (n = 70), Tay-Sachs disease (n = 62), Mucolipidosis (ML) II/III (n = 44), and Morquio-A (n = 40). Samples originated from 15 Indian states, with a predominance of pediatric cases. Detailed phenotypic, enzymatic, and genomic profiles were generated. Enzyme assays confirmed markedly reduced activity in most cases, with variable residual activity noted in few LSDs. Genetic analyses using Sanger sequencing, PCR-RFLP, targeted gene panel sequencing, and/ or whole exome sequencing detected causative variants. Notably, c.1469T > C in the IDUA gene (29.4% in Hurler disease), c.230 C > G in the GALNS gene (22.5% in Morquio-A disease), c.1448T > C in the GBA1 gene (56% in Gaucher disease), and c.1385 C > T and c.964G > T in the HEXA gene (11.3% and 8.1% respectively in Tay-Sachs disease) were the most common variants. Several novel, private mutations were also identified, broadening the mutational landscape of LSDs. The present study represents a scalable model for rare disease research in low- and middle-income countries. This resource lays the foundation for genotype-phenotype correlation studies, natural history analyses, and future precision medicine strategies tailored to the Indian population.
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.
Human Neuraminidase 3 reduces the severity of Tay-Sachs disease symptoms in a mouse model.
Tay-Sachs disease (TSD) is a neurodegenerative disorder caused by mutations in the HEXA gene, encoding the α-subunit of β-hexosaminidase A. HexA deficiency leads to impaired degradation and accumulation of GM2 ganglioside, causing progressive neurodegeneration in patients. Interestingly, Hexa-/- mice show a relatively mild phenotype, suggesting degradation of stored GM2 ganglioside through a 'bypass' involving a sialidase. To investigate whether sialidase Neu3 contributes to GM2 degradation, mice deficient in both HEXA and NEU3, Hexa-/-Neu3-/-, were generated. Abnormal GM2 accumulation was revealed in the brains of Hexa-/-Neu3-/- mice using thin-layer chromatography and mass spectrometric analyses. Immunohistological and histological analyses indicated astrogliosis, Purkinje cell loss, and progressive neurodegeneration. Furthermore, the mice exhibited marked neurological abnormalities, including slowed movement, ataxia, and tremors, as well as a shortened lifespan of approximately 20 weeks. Hence, Hexa-/-Neu3-/- mice, which mimic the neuropathological and clinical abnormalities observed in patients, were considered the early-onset TSD model. The role of endogenous human Neu3 in GM2 degradation remains unknown. To evaluate its therapeutic potential, we administered AAVrh10-hNeu3 intrathecally to 8-week-old Hexa-/-Neu3-/- mice, either alone or with an anti-inflammatory agent, Istradefylline. Treatment with human Neu3 and Istradefylline extended lifespan to 28 weeks, improved body weight, and reduced GM2 accumulation. Additionally, fewer lysosomal LAMP1- and TUNEL-positive cells, and higher CNPase levels were revealed. Rotarod and footprint analyses showed improvements at 20 weeks. Our results provide the first in vivo evidence that AAV-mediated human Neu3 expression and Istradefylline may slow disease progression, reduce neuropathology, and lessen motor deficits in the Hexa-/-Neu3-/- mouse model of TSD.
