apo A-IV

apo A-IV

A gene that encodes apo A-IV; allelic polymorphism in apo A-IV results in the substitution of histidine for glutamine at position 360 near the COOH terminus, generating the isoform apo IV-2, which attenutates the hypercholesterolemic response to dietary cholesterol. See Apolipoprotein A-IV.
