E3 ubiquitin-protein ligase. Together with the phosphatase EPM2A/laforin, appears to be involved in the clearance of toxic polyglucosan and protein aggregates via multiple pathways. In complex with EPM2A/laforin and HSP70, suppresses the cellular toxicity of misfolded proteins by promoting their degradation through the ubiquitin-proteasome system (UPS). Ubiquitinates the glycogen-targeting protein phosphatase subunits PPP1R3C/PTG and PPP1R3D in a laforin-dependent manner and targets them for pro

Myoclonic epilepsy of Lafora 2
A form of progressive myoclonic epilepsy, a clinically and genetically heterogeneous group of disorders defined by the combination of action and reflex myoclonus, other types of epileptic seizures, and progressive neurodegeneration and neurocognitive impairment. MELF2 is an autosomal recessive, severe form characterized by onset of progressive neurodegeneration between 8 and 18 years of age. Initial features can include headache, myoclonic jerks, generalized seizures, and often visual hallucination. Typically, as seizures increase in frequency, cognitive function declines towards dementia, and affected individuals die usually within 10 years after onset. At the cellular level, MELF2 is characterized by accumulation of starch-like polyglucosans called Lafora bodies (LBs) that are most abundant in organs with the highest glucose metabolism: brain, heart, liver and skeletal muscle.

Progressive Myoclonic Epilepsies - A Pragmatic Review.
Progressive Myoclonus Epilepsy (PME) is a rare and complex group of inherited neurodegenerative disorders characterized by progressively worsening myoclonus, cognitive impairment, tonic-clonic seizures and ataxia. The clinical features and genetic underpinnings of PME are diverse, with approximately 80% of individuals now able to receive a molecular diagnosis. This review outlines the clinical phenotypes, genotypes, and management strategies for PME. Literature search for publications on PME in the preceding 20 years, with emphasis for the past one decade, performed using Medline, JSTOR (journal storage) and PubMed databases. In PME progression of symptoms can vary widely among patients, with some experiencing rapid deterioration while others may have a slower rate of decline. Lafora Disease, characterized by the presence of Lafora bodies in tissues, Unverricht-Lundborg Disease (EPM1), caused by mutations in the CSTB gene, Myoclonic Epilepsy with Ragged-Red Fibers (MERRF), a mitochondrial disorder and Neuronal Ceroid Lipofuscinoses (NCL) make up the major chunk of PME syndromes. In the workup of PME, certain clinical and electroencephalogram (EEG) findings can help differentiate the specific etiologies. Valproic acid, perampanel, phenobarbitone and zonisamide are frequently prescribed as a treatment for various seizure types associated with PME. They are effective for managing both myoclonic and generalized tonic-clonic seizures. However, patients often have a progressive course and may find their myoclonus resistant to treatment. This review explores the clinical features and genetic factors associated with the more prevalent as well as recently described forms of PME for effective clinical evaluation, and suggests management strategies for this challenging condition.
Lafora disease gene therapy: EPM2A but not EPM2B overexpression results in Lafora body formation.
Lafora disease (LD) is a fatal teenage-onset neurodegenerative epilepsy caused by loss-of-function mutations of the genes encoding the laforin phosphatase-malin E3 ubiquitin ligase complex. This complex regulates glycogen structural integrity, through yet unclear mechanisms. Deficiencies of the complex lead few glycogen molecules at a time to misshape, precipitate and cumulate into toxic Lafora bodies (LBs) that drive LD. We developed an intrathecal AAV9-based gene therapy for malin-deficient LD and obtained preclinical efficacy without toxicity. A similar gene therapy for laforin-deficient LD also afforded efficacy, but with a relatively narrow therapeutic window. When overexpressed, laforin paradoxically led to LB generation and did so at a rate higher than in LD. The phenomenon was invariably observed first and dominantly in dorsal root ganglia (DRG) and occurred irrespective of where in the CSF axis the viral vector was delivered. Laforin overexpression-mediated LB formation represents novel biology, which we characterize and show that it occurs independently of laforin and malin's enzymatic activities. The accumulations are time-dependent, which toward clinical development will necessitate longer preclinical and clinical safety monitoring. The effect is strongest with species mismatch (i.e., expression of human laforin in mice), which may require matched-species preclinical development. Finally, the DRG are sentinel, and their pathology and neurophysiology can serve to monitor the iatrogenic toxicity. Our work suggests a clear gene therapy development path for malin-deficient LD, and sets important guardrails for gene therapy for laforin-dependent LD. It also opens a new avenue to understanding the basic biologies of glycogen quality control and LD.
Drug-Resistant Early-Onset Progressive Myoclonic Epilepsy Revealing Lafora Disease: A Case Report.
Lafora disease is a rare, autosomal recessive progressive myoclonic epilepsy characterized by drug-resistant seizures, myoclonus, and cognitive decline. We present the case of a 25-year-old woman with an unusually early onset of epilepsy at three years of age, progressive neurological deterioration, and a positive family history of progressive myoclonic epilepsy. The patient developed multiple seizure types, including generalized tonic-clonic seizures, atonic seizures, and stimulus-sensitive myoclonus, accompanied by progressive cognitive impairment. Electroencephalography (EEG) demonstrated generalized epileptiform discharges with frontocentral predominance and photosensitivity. Brain magnetic resonance imaging (MRI) revealed periventricular and parietal white matter changes with mild white matter reduction, likely related to a perinatal hypoxic-ischemic insult. Despite extensive antiseizure medication polytherapy and vagus nerve stimulation, seizures remained refractory. Although the skin biopsy was negative, the muscle biopsy showed ultrastructural changes consistent with Lafora disease. Genetic testing confirmed a pathogenic mutation in the EPM2B gene, establishing the diagnosis. This case highlights the diagnostic challenges of Lafora disease and the importance of prioritizing genetic testing in early-onset, drug-resistant epilepsy when standard diagnostic evaluations are nondiagnostic.
The biochemical dynamics of the glycogen phosphatase laforin directly impact brain metabolism.
Laforin is the only known glycogen phosphatase. Mutations in the laforin gene lead to the fatal childhood dementia and progressive myoclonic epilepsy known as Lafora disease (LD). A hallmark of LD is aberrant, cytoplasmic, glycogen-like aggregates known as Lafora bodies. Surprisingly, recent reports indicate that overexpression of a phosphatase-deficient laforin mutant, with the catalytic cysteine mutated to serine (LCS), prevented the formation of Lafora bodies in a laforin KO mouse model. This finding led to questions regarding the biological relevance of laforin phosphatase activity and its role in LD etiology. In this study, we defined the in vitro and in vivo effects of the LCS mutation. LCS protein lacks catalytic activity but exhibits significantly higher binding to phosphate and long glucan chains compared with WT laforin. In addition, LCS exhibits altered dynamics via hydrogen-deuterium exchange mass spectrometry and interacts more robustly with its binding partners malin and protein targeting to glycogen. We demonstrate that these altered dynamics result in aberrant retention of the LCS protein in the brain of the LCS knock-in mouse model, compared with laforin levels in WT mice. To examine the metabolic consequences of these biophysical changes, we compared the brain metabolomic phenotypes of LCS mice to WT and laforin KO mice. Furthermore, LCS mice display a distinct and significant global perturbation in metabolism. These results indicate a key signaling role for glycogen phosphorylation in glycogen metabolism, revealing an important biological role for laforin catalytic phosphatase activity.
Neuronal hyperexcitability: A key to unraveling hippocampal synaptic dysfunction in Lafora disease.
Lafora disease (LD) is a rare progressive disorder caused by mutations in the EPM2A or EPM2B genes, characterized by the accumulation of Lafora bodies, drug-resistant epilepsy, and cognitive decline. To investigate the early molecular mechanisms of LD, we studied electrophysiological changes in the dentate gyrus (DG) of the Epm2aR240X knock-in mouse model at various ages. Electrophysiological recordings measured neuronal membrane properties, epileptic-like activity, epileptic thresholds, and synaptic plasticity in Epm2aR240X mice at 1, 3, and 12 months. We also employed Periodic Acid-Schiff (PAS) diastase staining, immunofluorescence, and Western blotting to detect Lafora bodies, amyloid beta deposition, and the expression of glutamate receptor subunits. Epileptic-like activity began at 1 month and intensified with age. Aberrant long-term potentiation (LTP) appeared at 3 months and worsened by 12 months. Notably, cannabidiol treatment reduced excitability and restored LTP in older mice, suggesting its potential therapeutic value. The reversibility of synaptopathy, even at advanced stages, reinforces the importance of early detection of hyperexcitability and the development of effective therapeutic approaches.
