Niemann-Pick disease C1
A lysosomal storage disorder that affects the viscera and the central nervous system. It is due to defective intracellular processing and transport of low-density lipoprotein derived cholesterol. It causes accumulation of cholesterol in lysosomes, with delayed induction of cholesterol homeostatic reactions. Niemann-Pick disease type C1 has a highly variable clinical phenotype. Clinical features include variable hepatosplenomegaly and severe progressive neurological dysfunction such as ataxia, dystonia and dementia. The age of onset can vary from infancy to late adulthood. An allelic variant of Niemann-Pick disease type C1 is found in people with Nova Scotia ancestry. Patients with the Nova Scotian clinical variant are less severely affected.

Comparison of neonatal systemic and intracerebroventricular AAV9 gene therapy delivery demonstrating improved behavioral and phenotypic outcomes in a mouse model of Niemann-Pick disease, type C1.
Niemann-Pick disease, type C (NPC), is an inherited fatal lysosomal storage disorder caused by a mutation in the NPC1 or NPC2 genes and characterized by impaired lysosomal cholesterol export. Previous studies have demonstrated that delivery of the NPC1 gene to the central nervous system (CNS) via an adeno-associated virus (AAV) can substantially improve lifespan and mitigate signs of disease in Npc1-deficient mouse models of NPC. To determine the optimal parameters for an efficacious AAV-based gene therapy for NPC, we measured the survival and disease phenotypes of mice treated systemically as neonates or at weaning age, along with neonatal mice treated via intracerebroventricular (ICV) delivery, with a construct containing either a ubiquitous truncated EF1α promoter or a truncated Mecp2 promoter. While all constructs and delivery methods resulted in improvement compared with baseline, mice treated as neonates survived significantly longer and experienced slower disease progression compared with those treated systemically at weaning age. Systemic delivery to neonates was capable of increasing survival and phenotypic improvement comparable to that of ICV delivery, and neonatal systemic and ICV delivery were both similarly capable of near-total Purkinje cell rescue. We also found no difference between a ubiquitous EF1α-derived promoter and an Mecp2-derived promoter. Ultimately, early treatment with maximal access to the CNS, whether via systemic or direct CNS delivery, is key to the efficacy of gene therapy in treating NPC.
Investigation of dipyridamole-elicited signaling in the brain of Niemann Pick type C mice: A multi-omic study.
Niemann Pick type C1 (NPC1) is a rare, fatal disorder characterized by endo-lysosomal (EL) lipid accumulation that leads to damage of both peripheral organs and central nervous system, with cerebellum and hippocampus being particularly affected. Currently very few therapeutic options exist in Europe for NPC. In fact, miglustat is the only approved drug and L-acetylleucine was recently granted for marketing authorization by European Medicine Agency. Thus, the identification of new treatments is mandatory. We have previously demonstrated that dipyridamole (DIP), an approved medicine that is clinically employed as an antiplatelet agent, could rescue recognition memory and increase hippocampal expression of calbindin. On the contrary, the drug was unable to improve cerebellar-dependent motor function. In order to elucidate the mechanism of these region-specific changes induced by DIP, in this work we performed a multi-omic analysis of genes and proteins modulated by the treatment in the hippocampus and cerebellum of a mouse model of NPC1 (Npc1-/-). Our results revealed that DIP significantly affected various pathways in the hippocampus at protein level, but it had no significant impact on pathways in the cerebellum (either at gene or protein level). Interestingly, the most affected pathways in the hippocampus of Npc1-/- mice administered with DIP were those related to cGMP-PKG activation and to mitochondrial function. Our results paved the way to test DIP in experimental models of other neurodegenerative disorders, such as Alzheimer's disease that is similarly marked by hippocampal and mitochondrial dysfunctions.
Convergent Validity of the Fine Motor, Speech, and Cognitive Domains of the 5-Domain Niemann-Pick Disease Type C Clinical Severity Scale.
The 5-Domain Niemann Pick Type C Clinical Severity Scale (5DNPCCSS) is used in clinical practice and trials. Although psychometric data support the clinical meaningfulness of the concepts and the scale's interrater reliability, more information is needed to support its construct validity. Here, we evaluated the convergent validity of the Cognition, Speech, and Fine Motor domains. Data from 121 individuals with Niemann-Pick disease type C were drawn from several studies conducted at 2 US sites. Direct standardized assessments included the Nine-Hole pegboard or Purdue pegboard, a portion of the Clinical Evaluation of Language Fundamentals, and the age-appropriate Wechsler IQ test or the Mullen Scales of Early Learning. The 5DNPCCSS domains were significantly related in the expected directions to their respective direct assessments, supporting their construct validity. In combination with previous evidence presented for the Ambulation and Swallow domains, these results support the fitness of purpose of the (5DNPCCSS for clinical studies in Niemann-Pick disease type C.

Early Diagnosis of Nieman-Pick Disease Type C and Rapid Response of Gelastic Cataplexy to Treatment With N-Acetyl-L-Leucine: A Case Report.
BACKGROUND Niemann-Pick disease type C (NPC) is a rare, progressive neurodegenerative lysosomal storage disorder often diagnosed in childhood after the onset of neurological symptoms. Gelastic cataplexy - the sudden loss of muscle tone associated with laughter but remaining consciousness - is quite specific for NPC. This report describes the case of a 4-year-old boy with NPC presenting with gelastic cataplexy who responded to treatment with N-acetyl-L-leucine (NALL). CASE REPORT We present the case of a patient who first presented in the genetics clinic due to hepatosplenomegaly, dysmorphic features, and milestone delay at 2 years old. He had a history of cholestatic jaundice and hepatosplenomegaly at 2 months old. Granulomatous hepatitis of unknown origin was diagnosed by liver biopsy, and then the cholestatic jaundice resolved. The diagnosis of NPC was made, confirmed by compound heterozygous missense likely pathogenic in NPC1 (NM_000271.5): one known; c.2072C>T (p.Pro691Leu), and one novel; c.2805A>G (p.Ile935Met) at the age of 3 years. He then developed gelastic cataplexy at the age of 4 years, and a clinical improvement was observed within the first month after receiving NALL, including a significant decrease in cataplexy episodes, improved motor function, and reduced splenomegaly. CONCLUSIONS This case highlights the critical role of early genomic diagnosis in NPC, enabling prompt management of worsening neurological symptoms and potentially responding to treatment with NALL.
[Inherited metabolic disease presenting as a psychiatric disorder].
A 25-year-old man with autism was admitted for suspected psychosis. He had jaundice, abnormal liver tests, splenomegaly, and progressive cognitive decline with vertical gaze palsy. Antipsychotics and ECT were ineffective. Family history (sister with cognitive problems and splenomegaly) prompted genetic testing, revealing two pathogenic NPC1 variants, confirming Niemann-Pick type C. This case highlights a rare adult-onset psychiatric NPC and the importance of early multidisciplinary assessment and relative involvement.
