Paraoxonase 1 genotype-phenotype correlation in patients with metabolic syndrome.

TL;DRAbstract

The aim of the study was to investigate the influence of three single nucleotide polymorphisms (SNPs) (-108C>T, -162A>G and -909G>C) from the promoter region of paraoxonase 1 (PON1) gene on the enzyme activity, in patients with metabolic syndrome (MS). The study group consisted of 61 individuals with MS and the control group of 73 individuals without MS, matched for age and gender. For each individual, clinical and genetic parameters with possible influence on PON1 activities (paraoxonase, arylesterase and lactonase) were measured. PON1 genotyping was performed with PCR-RFLP, using specific primers and restriction enzymes. We found no differences for distribution of PON1 -108C>T, -162A>G and -909G>C polymorphisms, between the two groups (p-NS). The -108C>T and -909G>C polymorphisms were associated with paraoxonase (p=0.03, p=0.006, respectively), arylesterase (p<0.001, p<0.001, respectively) and lactonase (p<0.001, p<0.001, respectively) activities. The -162A>G polymorphism was not ass
