Glycogen synthase GYS1 overactivation contributes to glycogen insolubility and malto-oligoglucan-associated neurodegenerative disease. [PDF]

EMBO J
Polyglucosans are glycogen molecules with overlong chains, which are hyperphosphorylated in the neurodegenerative Lafora disease (LD). Brain polyglucosan bodies (PBs) cause fatal neurodegenerative diseases including Lafora disease and adult polyglucosan ...

Skeletal Muscle Glycogen Chain Length Correlates with Insolubility in Mouse Models of Polyglucosan-Associated Neurodegenerative Diseases

Cell Reports, 2019
Summary: Lafora disease (LD) and adult polyglucosan body disease (APBD) are glycogen storage diseases characterized by a pathogenic buildup of insoluble glycogen. Mechanisms causing glycogen insolubility are poorly understood.

Peripheral neuropathy and cognitive impairment associated with a novel monoallelic HARS variant

Annals of Clinical and Translational Neurology, 2019
Background A 49‐year‐old male presented with late‐onset demyelinating peripheral neuropathy, cerebellar atrophy, and cognitive deficit. Nerve biopsy revealed intra‐axonal inclusions suggestive of polyglucosan bodies, raising the suspicion of adult ...

Analysis of GBE1 mutations via protein expression studies in glycogen storage disease type IV: A report on a non-progressive form with a literature review

Molecular Genetics and Metabolism Reports, 2018
Background: Glycogen storage disease type IV (GSD IV), caused by GBE1 mutations, has a quite wide phenotypic variation. While the classic hepatic form and the perinatal/neonatal neuromuscular forms result in early mortality, milder manifestations include

Characterisation of phenotypic patterns in equine exercise‐associated myopathies

Equine Veterinary Journal, Volume 57, Issue 2, Page 347-361, March 2025.
Abstract Background Equine exercise‐associated myopathies are prevalent, clinically heterogeneous, generally idiopathic disorders characterised by episodes of myofibre damage that occur in association with exercise. Episodes are intermittent and vary within and between affected horses and across breeds.

Vacuolar myopathy with monoclonal gammopathy and stiffness (VAMMGAS)

European Journal of Neurology, Volume 32, Issue 1, January 2025.
Abstract Background Monoclonal gammopathy (MG) has been reported in association with numerous neurological disorders but the spectrum of MG‐associated myopathies remains poorly described. Objective To report a newly acquired myopathy associated with MG.

Temporopolar blurring signifies abnormalities of white matter in mesial temporal lobe epilepsy

Annals of Clinical and Translational Neurology, Volume 11, Issue 11, Page 2932-2945, November 2024.
Abstract Objective The single‐center retrospective cohort study investigated underlying pathogenic mechanisms and clinical significance of patients with temporal lobe epilepsy and hippocampal sclerosis (TLE‐HS), in the presence/absence of gray–white matter abnormalities (usually called “blurring”; GMB) in ipsilateral temporopolar region (TPR) on MRI ...

What can pediatricians learn from adult inherited metabolic diseases?

Journal of Inherited Metabolic Disease, Volume 47, Issue 5, Page 876-884, September 2024.
Abstract The field of inherited metabolic diseases (IMD) has initially emerged and developed over decades in pediatric departments. Still, today, about 50% of patients with IMD are adults, and adult metabolic medicine (AMM) is getting more structured at national and international levels.

Unraveling a history of overlap: A phenotypic comparison of RBCK1‐related disease and glycogen storage disease type IV

American Journal of Medical Genetics Part A, Volume 194, Issue 7, July 2024.
Abstract RBCK1‐related disease is a rare, multisystemic disorder for which our current understanding of the natural history is limited. A number of individuals initially carried clinical diagnoses of glycogen storage disease IV (GSD IV), but were later found to harbor RBCK1 pathogenic variants, demonstrating challenges of correctly diagnosing RBCK1 ...
