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.
First Reported Case of CLN5 Disease in Japan: Identification of a Novel Homozygous Pathogenic Variant Through Whole Genome Sequencing.
Neuronal ceroid lipofuscinoses (NCL) belong to a group of inherited neurodegenerative diseases characterized by psychomotor regression, seizures, and visual impairment, resulting from intracellular accumulation of lipofuscin. CLN5, a subtype typically manifesting between ages 4 to 17, is particularly rare in non-Finnish populations. Here, we report the first Japanese case of CLN5 in a 12-year-old girl with progressive myoclonic epilepsy and psychomotor regression. Initial assessments for common metabolic disorders, including GM2 gangliosidosis, were inconclusive. Trio-based genome sequencing (GS) identified a novel homozygous pathogenic variant in CLN5, confirming the diagnosis at 10 years and 6 months of age. Subsequent evaluations revealed progressive cerebral and cerebellar atrophy and vision loss. This case underscores the importance of GS in diagnosing rare neurodegenerative diseases and highlights the clinical spectrum of CLN5, which presents with rapid neurological decline. Expanding diagnostic frameworks with genetic testing is critical for early diagnosis and potential therapeutic interventions in CLN5 and related NCL disorders.
New multiplex LC-MS/MS method for lipid biomarker analysis of inherited neurodegenerative metabolic diseases.
A significant number of inherited neurodegenerative metabolic diseases (NMDs) arise from altered lipid metabolism, including impaired degradation of sphingolipids and dysfunction in organelle-related machineries involved in lipid processing and trafficking. These lipid dysregulations profoundly impact cellular membranes, signaling pathways, and myelin integrity, contributing to the complex and multisystemic clinical phenotypes characteristic of NMD, which often complicate diagnosis and delay treatment initiation. Here, we present a high-throughput, multiplex LC-MS/MS method for the analysis of an extended panel of NMD biomarkers in plasma and dried blood spots. One-step sample extraction and targeted LC-MS/MS acquisitions in positive and negative ionization allowed the simultaneous measurement of 13 diagnostic biomarkers associated with GM1 and GM2 gangliosidosis, Fabry, Gaucher, and Krabbe diseases, acid sphingomyelinase deficiency, Niemann-Pick disease type C, X-linked adrenoleukodystrophy, peroxisomal biogenesis disorders (Zellweger syndrome), metachromatic leukodystrophy, and mental retardation, enteropathy, deafness, neuropathy, ichthyosis, keratoderma (MEDNIK)/MEDNIK-like syndromes, a disorder of cellular trafficking. The method was analytically and clinically validated, confirming the diagnosis of all targeted NMDs in samples from 89 patients. Additionally, the method allowed the differentiation of X-linked adrenoleukodystrophy from peroxisomal biogenesis disorder and revealed the elevation of C18- and C16-sulfatides in Krabbe disease and MEDNIK syndrome, respectively. This multiplex assay enhances diagnostic efficiency and expands the discovery of novel biomarkers, enabling the quantification of diagnostic markers for a wide range of NMDs. The method is suitable for diagnosis of NMD, as a first- or second-tier test in neonatal screening, as confirmatory testing of variant of unknown significance in genetic panels and for longitudinal monitoring in treatable diseases.

Similarities and Differences in the Late-Onset GM2 Gangliosidoses: Tay-Sachs and Sandhoff Diseases.
The two predominating subtypes of late-onset GM2 gangliosidosis are late-onset Tay-Sachs (LOTS) and late-onset Sandhoff disease (LOSD). Due to shared deficiencies of ß-hexosamindase A and significant clinical overlap, the two diseases have been considered indistinguishable. However, a growing body of evidence supports the notion of several distinctions between the two diseases. In this study, we highlight these distinctions through the cross-sectional evaluation of 27 late-onset GM2 gangliosidosis participants. Twenty-one participants with LOTS and 6 with LOSD were included in this study. We performed physical examinations alongside assessments for gait, balance, muscle strength, ataxia, nerve conduction velocities, and analyzed brain magnetic resonance imaging. Lower limb weakness (95% in LOTS, 100% in LOSD) and later development of upper limb weakness (90% in LOTS, 83% in LOSD) was highly prevalent in both cohorts. Accompanying gait disturbances, balance issues, and dysmetria (as assessed by the brief ataxia rating scale [BARS]) were also prevalent in both cohorts. Strength testing for the quadriceps and hamstrings demonstrated weakness in both cohorts, primarily impacting extensor muscles. Supratentorial gray and white matter volumes in both cohorts were similar to normative data. In contrast, BARS scores for dysarthria and oculomotor dysfunction were present and heterogenous in LOTS participants and absent in LOSD participants. 24% of LOTS participants and none of the LOSD participants had a history of neuropsychiatric symptoms. Cerebellar volume including lobules V and VI were lower in LOTS compared to LOSD and normative data. However, length dependent sensory neuropathy was present in all LOSD participants but absent in LOTS participants. Dysfunction of the posterior cerebellum (lobules VI, VII, and IX) has been shown to cause cerebellar cognitive affective syndrome (CCAS), that includes cognitive and behavioral disturbances. Furthermore, cerebellar dysfunction of lobules V and VI has been linked to dysarthric speech, and dysfunction of the posterior cerebellum has been linked to oculomotor symptoms. The finding of low cerebellar lobule volumes in LOTS, suggests the distinctive features of the LOTS phenotype are related to cerebellar dysfunction. However, the sensory symptoms unique to LOSD remains a mystery. The molecular and biochemical basis for the dichotomy between the LOTS and LOSD phenotypes requires further investigation.
