Chitotriosidase as a biomarker for gangliosidoses

Molecular Genetics and Metabolism Reports, 2021
Elevated serum chitotriosidase (CHITO) is an indication of macrophage activation, and its capacity have been explored as a marker of inflammation in a number of disease states.

Diagnostic Dilemma in an Infant With Sound-Triggered Motor Events: Reflex Epilepsy Versus Exaggerated Startle-A Case Report. [PDF]

Clin Case Rep
ABSTRACT Auditory‐triggered motor events in infancy present a significant diagnostic challenge due to overlap between epileptic and non‐epileptic startle phenomena. We report the case of a term female infant with neonatal‐onset seizures and subsequent development of reproducible sound‐triggered jerky movements, raising diagnostic uncertainty between ...

Alkaline Phosphatase and Infantile GM1 Gangliosidosis: A Simple Biomarker for a Complex Disease? [PDF]

JIMD Rep
ABSTRACT GM1 gangliosidosis is a lysosomal storage disease (LSD) caused by β‐galactosidase deficiency, characterized by the accumulation of gangliosides in various tissues. Among different GM1 forms (infantile form, late‐infantile and juvenile form, and late‐onset form), the infantile form is the most severe: despite an early clinical onset with rapid ...

The diagnostic journey for patients with late-onset GM2 Gangliosidoses

Molecular Genetics and Metabolism Reports, 2023
Late-onset forms of GM2 gangliosidosis―mainly, Tay-Sachs disease and Sandhoff disease―are under-recognized in clinical practice. In these rare lysosomal storage disorders, deficiency of β-hexosaminidase A results in excessive accumulation of GM2 ...

Positioning Head Tilt in Canine Lysosomal Storage Disease: A Retrospective Observational Descriptive Study

Frontiers in Veterinary Science, 2021
Positioning head tilt is a neurological sign that has recently been described in dogs with congenital cerebellar malformations. This head tilt is triggered in response to head movement and is believed to be caused by a lack of inhibition of the ...

From Molecule to Meaning: Neuronopathic Biomarkers and Clinical Relevance in GM1. [PDF]

J Inherit Metab Dis
ABSTRACT GM1 gangliosidosis is a rare, progressively neurodegenerative lysosomal storage disorder characterized by profound central nervous system involvement and substantial clinical heterogeneity. The development of reliable biomarkers is essential for tracking disease progression, stratifying patients, and advancing clinical trial readiness. Primary

Characterization of inducible models of Tay-Sachs and related disease. [PDF]

PLoS Genetics, 2012
Tay-Sachs and Sandhoff diseases are lethal inborn errors of acid β-N-acetylhexosaminidase activity, characterized by lysosomal storage of GM2 ganglioside and related glycoconjugates in the nervous system.

Conditional expression of human β-hexosaminidase in the neurons of Sandhoff disease rescues mice from neurodegeneration but not neuroinflammation [PDF]

, 2012
This study evaluated whether GM(2) ganglioside storage is necessary for neurodegeneration and neuroinflammation by performing β-hexosaminidase rescue experiments in neurons of HexB(−/−) mice.

Epidemiology of progressive intellectual and neurological deterioration in UK children. [PDF]

Dev Med Child Neurol
This study of PIND in UK children was carried out via the British Paediatric Surveillance Unit from 1997 to 2024. It identified six cases of vCJD. 2367 children had other diagnoses explain their deterioration. There were 259 other diseases in the diagnosed group.
