β¦ Synopsis
Two cases of Niemann-Pick disease type C are described in order to illustrate the variable neurological features of this rare condition. One presented with a predominantly akinetic-rigid syndrome at the age of 5 years. The second developed progressive ataxia, accompanied by a vertical gaze palsy, when she was 13. Neither patient had hepatosplenomegaly; the diagnosis of Niemann-Pick disease type C was based on finding foamy storage cells in bone marrow aspirates.

## Abstract NiemannβPick disease type C (NPC) is a deadly neurodegenerative disease often caused by mutation in a gene called NPC1, which results in the accumulation of unesterified cholesterol and glycosphingolipids in the endosomalβlysosomal system. Most studies on the mechanisms of neurodegenera
The lariat branch point sequence (BPS) is crucial for splicing pre-mRNA even if BPS mutations have infrequently been reported in human disease. In two siblings with Niemann-Pick type C (NPC) disease we identified two mutations of the NPC1 gene: i) one in exon 20 (c.2932C>T) (p.R978C) previously repo
