Niemann-pick Disease, Type C2; Npc2

Description

Niemann-Pick type C (NPC) disease is an autosomal recessive lipid storage disorder characterized by progressive neurodegeneration. Approximately 95% of cases are caused by mutations in the NPC1 gene (OMIM ), referred to as type C1 (OMIM ); 5% are caused by mutations in the NPC2 gene (OMIM ), referred to as type C2. The clinical manifestations of types C1 (OMIM ) and C2 are similar because the respective genes are both involved in egress of lipids, particularly cholesterol, from late endosomes or lysosomes (summary by Vance, 2006).
