Six novel NPC1 mutations in Chinese patients with Niemann-Pick disease type C.
In patients with Niemann-Pick disease type C (NPC), an autosomal recessive lipid storage disorder, neurodegeneration can occur in early life. Vertical ophthalmoplegia and extrapyramidal signs may be seen. Cholestatic jaundice and hepatosplenomegaly occur frequently in patients with early onset disease, with bone marrow biopsies showing diffuse infiltration of foamy histiocytes. Cholesterol este...
متن کاملNiemann-Pick disease type C: mutations of NPC1 gene and the course of disease
Niemann-Pick disease type C (NP-C) is a rare autosomal recessive disorder caused by mutations in the NPC1 gene in 95% of cases. Consequently, unesterifi ed cholesterol accumulates in late endosomes/lysosomes causing extremely varied neurovisceral symptoms. For many countries including Croatia, there are no reported NP-C cases to date, mainly because the accurate diagnosis of NP-C requires not e...
متن کاملCharacterisation of two deletions involving NPC1 and flanking genes in Niemann-Pick type C disease patients.
Niemann-Pick type C (NPC) disease is an autosomal recessive lysosomal disorder characterised by the accumulation of a complex pattern of lipids in the lysosomal-late endosomal system. More than 300 disease-causing mutations have been identified so far in the NPC1 and NPC2 genes, including indel, missense, nonsense and splicing mutations. Only one genomic deletion, of more than 23 kb, has been p...
متن کاملOlfactory Deficits in Niemann-Pick Type C1 (NPC1) Disease
BACKGROUND Niemann-Pick type C disease (NPC) is a rare autosomal recessive lipid storage disease characterized by progressive neurodegeneration. As only a few studies have been conducted on the impact of NPC on sensory systems, we used a mutant mouse model (NPC1(-/-)) to examine the effects of this disorder to morphologically distinct regions of the olfactory system, namely the olfactory epithe...
متن کاملNiemann-Pick type C disease.
A 4-year-old Afghan girl born to consanguineous parents presented with progressive neurological regression and hepatomegaly noticed after one year of age. The child had hypotonia, repeated unexplained falls and facial dyskinesia. Bone marrow examination revealed presence of storage cells suggestive of Gauchers or Niemann Pick. Confirmatory study by lysosomal enzyme from leucocytes was normal fo...
