The Effects of PON1 Gene Q192R Variant on the Development of Uterine Leiomyoma in Turkish Patients

Abstract

Aim: This study aimed to analyze the relation between uterine leiomyoma (ULM) patients and p.Q192R polymorphism. Materials and Methods: ULM patients (n=76) and healthy women (n=103) were recruited from the Yeditepe University, Department of Gynecology and Obstetrics. The genotype and allele distribution of p.Q192R was analyzed by polymerase chain reaction and restriction fragment length polymorphism methods. Genotype and allele frequencies between study groups were calculated by the chi-square (chi(2)) and Fischer's exact test. Results: The frequency of the B allele was lower in patients (p<0.001) and the AB genotype showed a decreased risk for ULM development (p<0.001). The variation was unrelated to ULM size and number. There was no significant difference between p.Q192R genotype frequencies and fibroid size and number. Conclusion: The heterogeneous AB genotype of PON1 p.Q192R variation could be recognized as a low-risk parameter for the development of ULM in Turkish women.
