Evaluation of the Genetic Background of Patients with Niemann-Pick Disease
CONCLUSIONS: In this study, disease-causing variants were identified in three probands suspected of Niemann-Pick disease. Such results show the relatively high power of molecular techniques to assist clinicians with disease management, therapeutic strategies, and preventive options such as preimplantation genetic diagnosis and prenatal diagnosis.PMID:38618260 | PMC:PMC11015928 | DOI:10.61186/rbmb.12.3.386 (Source: Mol Biol Cell)

Plasma neurofilament light chain is increased in Niemann-Pick Type C but glial fibrillary acidic protein remains normal
This study investigated biomarker levels and diagnostic utility of plasma neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) in NPC compared to healthy controls.METHODS: Patients with NPC were recruited from a specialist assessment and management service. Data was available from an age and sex-matched healthy control group. NfL and GFAP were measured on Quanterix Simoa HD-X analysers and groups compared using generalised linear models. NfL levels were compared to, and percentiles derived from, recently developed NfL reference ranges.RESULTS: Plasma NfL was significantly elevated in 11 patients with ...

Familial Alzheimers disease associated with heterozygous NPC1 mutation
We describe a novel NPC1 heterozygous mutation harboured by different members of a family with autosomal dominant late-onset amnesic AD without NPC-associated features. A missense mutation in homozygous state in the same aminoacidic position has been previously reported in a patient with NPC with severe phenotype. The alteration of serum oxysterols in our family corroborates the pathogenic role of our NPC1 mutation. Our work, illustrating clinical and biochemical disease hallmarks associated with NPC1 heterozygosity in patients affected by AD, provides relevant insights into the pathogenetic mechanisms underlying this poss...

Long-term efficacy of intrathecal cyclodextrin in patients with Niemann-Pick disease type C
Niemann –Pick type C (NPC) is a rare lysosomal storage disease characterized by hepatosplenomegaly and progressive neurological deterioration due to abnormal intracellular cholesterol transport. Cyclic oligosaccharide 2-hydroxypropyl-β-cyclodextrin (HPBCD) is an effective treatment for NPC; however, few reports have shown its long-term efficacy and safety. To demonstrate long-term efficacy and safety of intrathecal HPBCD (IT-HPBCD) treatment for NPC, we herein reports five patients with NPC treated using IT-HPBCD for 4–11 years.

Can NPC1L1 inhibitors reduce the risk of biliary tract cancer? Evidence from a mendelian randomization study
Oxysterols have been implicated in biliary tract cancer (BTC), and Niemann-Pick C1 –like 1 (NPC1L1) has been associated with oxysterol uptake in biliary and intestinal cells. Thus, our study aims to investigate the potential causal link between genetically proxied NPC1L1 inhibitors and the risk of BTC. (Source: Digestive and Liver Disease)

NPC1L1 rs217434 A   & gt;  G as a Novel Single Nucleotide Polymorphism Related to Dyslipidemia in a Korean Population
This study provided evidence for a relationship between the NPC1L1 rs217434 A > G genotype and dyslipidemia in the Korean population, which highlights the potential of the NPC1L1 rs217434 A > G genotype as an early predictor of dyslipidemia.PMID:38280151 | DOI:10.1007/s10528-023-10649-6 (Source: Biochemical Genetics)
