NPC2 - NPC intracellular cholesterol transporter 2 Gene
Also Known as HE1; EDDM1
Species: Homo sapiens
About NPC2
This gene has 9 transcripts (splice variants), 216 orthologues and is associated with 7 phenotypes. Ubiquitous expression in lung (RPKM 202.8), thyroid (RPKM 113.6) and 25 other tissues.
Summary
This gene encodes a protein containing a lipid recognition domain. The encoded protein may function in regulating the transport of Cholesterol through the late endosomal/lysosomal system. Mutations in this gene have been associated with Niemann-Pick disease, type C2 and frontal lobe atrophy. [provided by RefSeq, Jul 2008]
