ANGPTL3 (ANGPTL-3) Human Active Protein

This gene encodes a member of a family of secreted proteins that function in angiogenesis. The encoded protein, which is expressed predominantly in the liver, is further processed into an N-terminal coiled-coil domain-containing chain and a C-terminal fibrinogen chain. The N-terminal chain is important for lipid metablism, while the C-terminal chain may be involved in angiogenesis. Mutations in this gene cause familial hypobetalipoproteinemia type 2.

ANGPTL3: Defects in ANGPTL3 are the cause of familial hypobetalipoproteinemia type 2 (FHBL2); also called combined hypobetalipoproteinemia familial. FHBL2 is a disorder of lipid metabolism characterized by less than 5th percentile age- and sex-specific levels of low density lipoproteins, and dietary fat malabsorption. Affected individuals present with combined hypolipidemia, consisting of extremely low plasma levels of LDL cholesterol, HDL cholesterol, and triglycerides.
