The child had hypotonia, repeated unexplained falls and facial dyskinesia. Bone marrow examination revealed presence of storage cells suggestive of Gauchers or Niemann Pick.

متن کاملNiemann-Pick disease type C
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...
متن کاملCyclodextrin overcomes deficient lysosome-to-endoplasmic reticulum transport of cholesterol in Niemann-Pick type C cells.
A handoff model has been proposed to explain the egress from lysosomes of cholesterol derived from receptor-mediated endocytosis of LDL. Cholesterol is first bound by soluble Niemann-Pick C2 (NPC2) protein, which hands off the cholesterol to the N-terminal domain of membrane-bound NPC1. Cells lacking NPC1 or NPC2 accumulate LDL-derived cholesterol in lysosomes and fail to deliver LDL cholestero...
متن کاملNiemann-Pick Type C Disease – Report on Results from the Niemann-Pick Type C Patient and Healthcare Professional Survey
Niemann-Pick type C disease (NPC) is a rare and progressive genetic condition that is associated with an abnormal accumulation of lysosomal lipids in the body, which manifests as a variety of neurological symptoms that range greatly in severity. Management focuses largely on treating symptoms, but recent developments have led to disease-specific therapy that can slow or stabilise the progressio...
