Abstract
Human serum paraoxonase (PON1) is an esterase that has been shown to decrease the susceptibility of lipoproteins to lipid peroxidation. We found a polymorphism of cytosine/thymidine (-108C/T, the number is from the ATG codon) in the upstream region of the PON1 gene. The luciferase activity was lower in the -108T allele than in the -108C allele. The serum PON1 concentrations in 132 normal subjects were as follows: -108CC>-108CT and>-108TT genotypes. The polymorphism upstream from the PON1 gene is associated with transcription of the PON1 gene and the serum PON1 concentration.
