Abstract
Paraoxonase 1 (PON1) enzyme plays a major role in antioxidant defense and protects
the cells against reactive species. The most common PON1 Q192R and L55M polymorphisms are responsible for a wide variation of PON1 activity,
which showed an up to 13-fold interindividual variation among the same genotype. PON1 genotypes were evaluated with the development of pancreatitis, colorectal cancer,
and hypothyroidism in a hospital-based, case-control study. Individuals with rs662
G allele had a two-fold risk of developing hypothyroidism. A weak association was found
between rs854560 T allele and pancreatitis. The results were preliminary. Further studies with a larger
number and detailed biochemical parameters are needed.
