CYP1A1 Gene Polymorphism in Korean Women with Endometriosis

Objective: To explore the association of the CYP 1A1 gene polymorphism with the risk of endometriosis in a Korean population. Design: Case-control study Methods: Two-hundred fifty two Korean women with surgically or histologically diagnosed endometriosis of stage I-IV (ASRM, 1997) were recruited, and 203 women with no evidence of endometriosis served as controls. CYP1A1 gene MspI polymorphism was analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism analysis. Results: There was no significant difference in the genotype or allele distribution of CYP1A1 gene polymorphism between patients with endometriosis and controls. And when classified by stage, there was also no significant difference in the genotype and allele distribution of CYP1A1 gene MspI polymorphism between patients with stage I-II or stage III-IV endometriosis and controls. Conclusion: These results suggest that CYP1A1 gene MspI polymorphism is not associated with the risk of endometriosis in the Korean women.
