The evaluation of two genetic polymorphisms of paraoxonase 1 in patients with pulmonary embolism

Background and Objective Pulmonary embolism (PE) is caused by some genetic factors for more than half patients. Paraoxonase 1 (PON1) has significant anti‐oxidative and anti‐inflammatory effects. According to our knowledge, there is no study researching the relation between PON 1 gene polymorphisms and PE in the literature. Therefore, it is aimed to research possible impacts of PON 1 Q192R and L55M polymorphisms on PE, considering anti‐inflammatory and anti‐oxidative effects of PON 1 in Turkish population. Methods One hundred and five PE patients and one hundred and seventeen controls were enrolled in this study. Genomic DNA was isolated and genotyped using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analyses for the PON1 gene Q192R and L55M polymorphisms. Results Any associations were not found between clinical and demographical characteristics of PE patients and the PON1 gene Q192R polymorphism; however, there were associations between surgery, chronic renal failure, and cerebrovascular disease on the history of patients and L55M polymorphism (P = .013, P = .037, and P = .031, respectively). Genotype and allele frequencies did not show any significant differences between patients and controls according to PON1 gene Q192R and L55M polymorphisms (P > .05). Conclusion The results of this study suggest that there is no correlation between PE and PON 1 gene Q192R and L55M polymorphisms in the Turkish population from the Central Black Sea region. Besides, whole genotypes and alleles of Q192R and L55M are not risk factors for patients with PE in this population.
