Niemann-Pick disease type C (NPC) is an autosomal recessive neurovisceral lipid storage with a wide spectrum of clinical phenotypes. At the cellular level, the disorder is characterized by accumulation of unesterified cholesterol and glycolipids in the lysosomal/late endosomal system. Approximatively 95% of patients have mutations in the NPC1 gene (mapped at 18q11) which encodes a large membran...
In the first part the properties of normal mammalian sphingomyelinases are reviewed: The lysosomal acid sphingomyelinase is a polymeric glycoprotein (subunit Mr between 28 000 and 70 000) which hydrolyses natural sphingomyelin, coloured and fluorescent semi-synthetic analogues (trinitrophenyl-aminolauryl-sphingomyelin and pyrenedecanoyl-sphingomyelin) and the synthetic analogue 2-N-hexadecanoyl...
A patient with Niemann-Pick disease is reported together with family studies. Her liver and bone marrow were shown to be infiltrated with sea blue histiocytes. Other organs, spleen and lung, were presumably also involved but histological proof was not obtained. Enzyme assay of leucocytes, lymphocytes, and cultured skin fibroblasts showed the patient to be deficient in sphingomyelinase activity....
Niemann-Pick disease type C (NP-C) is a rare, autosomal-recessive, progressive neurological disease caused by mutations in either the NPC1 gene (in 95% of cases) or the NPC2 gene. This observational, multicentre genetic screening study evaluated the frequency and phenotypes of NP-C in consecutive adult patients with neurological and psychiatric symptoms. Diagnostic testing for NP-C involved NPC...
The second case of infantile Niemann-Pick disease was reported in a Thai newborn baby who presented with respiratory distress and hepatosplenomegaly from birth and who succumbed from bronchopneumonia 20 days later. Autopsy examination showed generalized accumulation of foam cells in reticuloendothelial organs. The parenchymal cells of visceral organs as well as neurones in the central nervous s...
