Sialidosis
Lysosomal storage disease occurring as two types with various manifestations. Type 1 sialidosis (cherry red spot-myoclonus syndrome or normosomatic type) is late-onset and it is characterized by the formation of cherry red macular spots in childhood, progressive debilitating myoclonus, insiduous visual loss and rarely ataxia. The diagnosis can be confirmed by the screening of the urine for sialyloligosaccharides. Type 2 sialidosis (also known as dysmorphic type) occurs as several variants of increasing severity with earlier age of onset. It is characterized by the presence of abnormal somatic features including coarse facies and dysostosis multiplex, vertebral deformities, intellectual disability, cherry-red spot/myoclonus, sialuria, cytoplasmic vacuolation of peripheral lymphocytes, bone marrow cells and conjunctival epithelial cells.

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.
Alterations in secondary lipids are associated with neuroinflammation in the brain of Neu1-deficient mice.
Neu1 (lysosomal sialidase 1) is essential for removing sialic acid from oligosaccharides and glycoconjugates. Neu1 deficiency impairs lysosomal digestion, leading to sialidosis and sialoglycoprotein accumulation. It also increases lipids, including gangliosides GM3, GD3, GM4, and LM1, in the kidney, liver, and spleen. Neu1-/- mice display symptoms resembling Type II sialidosis, including enlarged spleen and liver, kidney issues, neurological problems, spinal defects, and oligosaccharide buildup. The study examined secondary lipid alterations and inflammation in the cortex and cerebellum of these mice. Lipidomic, molecular, and immunohistochemical analyses of tissues from 2 and 5 M Neu1-/- mice revealed reduced levels of lipids, including PC, PE, PS, and CL, along with increased pro-inflammatory cytokines and loss of oligodendrocytes and neurons. Signs of astrogliosis and microgliosis emerged in specific brain regions. These results indicate that reduced levels of glycerophospholipids could serve as an indicator of inflammation in sialidosis mice. Future research should investigate therapies targeting these lipid changes, as modulating glycerophospholipids might slow disease progression in sialidosis patients.
Failure of Allogeneic Transplant to Correct Sialidosis Despite Early Diagnosis and Full Donor Engraftment of Non-Carrier Leucocytes.
Sialidosis, also known as Mucolipidosis Type I, is a rare condition caused by defects in the NEU1 gene which causes the accumulation of sialylated peptides, oligosaccharides, and glycoproteins leading to neurological decline. Haematopoetic stem cell transplantation has been performed in the symptomatic phase twice in the literature but has failed to prevent deterioration. We report on a case where a 4-year-old child was diagnosed with pre-symptomatic sialidosis due to investigation following the incidental detection of a cherry-red spot prior to the onset of neurological symptoms. We performed haematopoetic stem cell transplantation with a matched unrelated cord blood unit with optimal timing prior to clinical decline, achieving full donor engraftment with a largely uneventful post-transplant recovery followed by a period of relative clinical stability. However, subsequent neurological decline detailed by clinical history and radiological findings has occurred suggesting a lack of disease responsiveness to transplantation despite optimal timing. We go on to provide supporting laboratory investigations detailing sialidosis fibroblast culture as part of a novel cross-correction assay and compare results to other transplant responsive lysosomal storage disorders such as mucopolysaccharidosis type 1-H and detail a lack of cross-correction in concordance with our clinical findings. We conclude that conventional allogeneic haematopoetic stem cell transplantation is not a viable disease-modifying treatment option in sialidosis, even when performed optimally in the pre-symptomatic phase, and suggest that alternative treatment options must be explored to improve outcomes in this condition.
Disorders in sialic acid metabolism and sialylation pathway.
Sialic acids (Sias) are acidic 9‑carbon monosaccharides. Both free Sias and conjugated Sias (sialylation) exist in the human body and have decisive impacts on human health and disease. Cellular free Sias are made via de novo biosynthesis, recycled from lysosomal salvage, and even by uptake of extracellular Sias, respectively. Sialylation of glycoproteins and glycolipids are catalyzed by sialyltransferases using CMP-Sia as the donor in the Golgi apparatus. In addition, free Sia can be degraded/catabolized into ManNAc and pyruvate in the cytosol. Overall, cellular free Sia and sialylation are kept at certain levels for normal cell functions. However, Sias deficiency and overproduction (accumulation), hyposialylation (undersialylation) and hypersialylation all cause disorders in the human body through a variety of mechanisms, but most of them are still not fully clarified. This review discusses recent understanding of disorders in Sia biosynthesis, salvage, catabolism, and sialylation pathways and therapeutic explorations for these disorders as well.
Sialidosis type I: How to alleviate disabling myoclonic seizures?-A multicenter analysis of eight cases and review of the literature.
Sialidosis type I (ST-1) is an autosomal-recessive, very rare, progressive lysosomal storage disorder caused by pathogenic variants in NEU1. It is clinically characterized by progressive ataxia, myoclonic seizures (MS), bilateral tonic-clonic seizures (BTCS), and distinctive ophthalmological findings. Given the lack of curative options, in this study, we investigated symptomatic treatment strategies, with a particular focus on the efficacy of antiseizure medications (ASMs). We describe the clinical course of a patient followed from diagnosis to 18 years of age, and review seven additional cases from our cohort. In parallel, we conducted a narrative review of the literature (PubMed, January 2010-September 2025) to identify published reports containing therapeutic data. Therapeutic responses were evaluated in a total of 33 cases (8 from our cohort, 25 from published sources). Although available data are insufficient to define standardized treatment guidelines, some ASMs, such as ACZ, PER, LEV, VPA, CZP, and ZNS, demonstrated fairly consistent efficacy in managing MS and BTCS. Sodium oxybate or deep-brain stimulation may be considered in refractory cases. Prospective documentation of clinical course and treatment outcomes-ideally through an international registry-is crucial to improve patient care and inform therapeutic strategies. Sialidosis type I (ST-1) is a very rare genetic disorder causing movement problems and seizures, with no cure available yet. We followed 8 patients and reviewed 25 published cases to assess treatments focusing on myoclonic seizure (MS) control. Some antiseizure medications showed benefit. However, we have too little data to make clear recommendations. To improve patients' treatment and to choose the most appropriate therapy, it would be important to follow patients over a longer period of time, for example, in an international registry.
