CLN2 Disease: Current Understandings, Challenges, and Future Directions.

Journal of child neurology2026 Jan

Neuronal ceroid lipofuscinosis type 2 (CLN2) disease is a rare neurodegenerative condition that rapidly progresses with language regression, loss of ambulation, blindness, intractable seizures, and premature death in childhood. Enzyme replacement therapy has transformed the clinical trajectory of CLN2 disease, and early genetic testing is crucial because enzyme replacement therapy cannot reverse clinical progression. Lack of clinician awareness of early clinical symptomatology, initially normal language development, and history of provoked or treatment-responsive seizures may contribute to diagnostic and treatments delays. There remain challenges in equitable enzyme replacement therapy access globally and implementation of dual treatment to address retinopathy. There is a need to better understand the phenotype of CLN2 disease in the era of enzyme replacement therapy, including children who receive treatment presymptomatically. Gene therapy is a promising curative treatment, notwithstanding the mixed clinical evidence on efficacy and challenges achieving widespread brain transgene expression. This review explores our current understanding of early clinical presentation of CLN2 disease, epilepsy phenotype, role of genetic testing, novel biomarkers, and precision treatments including enzyme replacement therapy.

Generation of Donor-Specific iPSC for Modelling Lysosomal Storage Disorders.

Methods in molecular biology (Clifton, N.J.)2026

iPSC technology has enabled the generation of human cell-based models of lysosomal storage disorders and has provided disease-relevant systems to undertake drug discovery or pre-clinical testing of gene- or cell-based therapies. Here, we provide a protocol to generate iPSCs derived from people with lysosomal storage disorders and illustrate expected results using a CLN2 disease donor-specific skin fibroblast culture. Protocol steps include lipofection of episomal plasmids, picking of putative iPSC colonies following live cell TRA-1-60 immunofluorescence, and quality control steps such as immunofluorescence for expression of undifferentiated cell markers, germ layer differentiation, and confirmation of pathological variant genotype. The iPSC generated by this protocol can be differentiated to several cell lineages and can be used with CRISPR/Cas technology to generate isogenic disease models.

Incidence and timing of diagnosis of neuronal ceroid lipofuscinosis type 2 (CLN2): A nationwide study using the French hospital discharge database.

European journal of paediatric neurology : EJPN : official journal of the European Paediatric Neurology Society2025 Dec 03

Neuronal ceroid lipofuscinoses (NCLs) are rare, progressive lysosomal neurodegenerative disorders. Among late-infantile onset forms (after 18 months of age), type 2 (CLN2 disease) is the most frequent. This study assessed the incidence and disease burden at diagnosis of CLN2 disease in France. This was a nationwide, population-based, retrospective study including all patients identified with CLN2 disease in the French Hospital Discharge Database (Programme de Médicalisation des Systèmes d'Information, PMSI) from January 2015 to December 2023. After a 2-year washout period to exclude prevalent patients, 51 children were considered to have been diagnosed with CLN2 disease over 7 years (2017-2023). Based on national birth statistics, this corresponds to an incidence of 0.99 cases of CLN2 disease per 100,000 live births. Median age at diagnosis was 5 years (interquartile range, 3-8), with a mean diagnostic delay of 19.1 ± 19.8 months from the first coded symptoms. Epilepsy (90.2 %) and intellectual disability (86.3 %) were the most frequently coded comorbidities. Of the 51 children, 84.3 % were hospitalized via emergency care, and 45.1 % required intensive care. Overall, 13 deaths (25.5 %) were reported, with median age at death of 9 years. This is the first nationwide epidemiological assessment of CLN2 disease in France. The results demonstrate substantial diagnostic delays and disease burden, underscoring the need for earlier diagnosis and referral to expert centers to optimize care and offer genetic counseling to parents before conceiving subsequent offspring.

Assessment of motor deterioration in a cynomolgus macaque with neuronal ceroid lipofuscinosis type 2 disease using two behavioral analyses.

The Journal of veterinary medical science2025 Nov 01

The classical late-infantile form of neuronal ceroid lipofuscinosis type 2 (CLN2 disease) is a fatal lysosomal disorder characterized by progressive motor decline and premature death. A CLN2 cynomolgus macaque (Macaca fascicularis) model closely replicates the late-stage clinical and pathological features of human CLN2. To evaluate motor deterioration in this model, we conducted two behavioral assessments-the CLN2 Macaque Clinical Rating Scale and the Apple test-from the pre-onset stage in one macaque. Hypokinesia was observed as the first symptom at 22 months of age, followed by a marked decline in forelimb movement from 27 months. These simple, non-invasive, and cost-effective tests are valuable tools for monitoring disease progression and may facilitate the future clinical evaluation of therapeutic strategies for CLN2.
