Record overview

LMPD IDLMP000386
Gene ID348
SpeciesHomo sapiens (Human)
Gene Nameapolipoprotein E
Gene SymbolAPOE
SynonymsAD2; APO-E; LDLCQ5; LPG
Alternate namesapolipoprotein E; apolipoprotein E3
Chromosome19
Map Location19q13.2
SummaryThe protein encoded by this gene is a major apoprotein of the chylomicron. It binds to a specific liver and peripheral cell receptor, and is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. This gene maps to chromosome 19 in a cluster with the related apolipoprotein C1 and C2 genes. Mutations in this gene result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]
