Influence of the CYP1B1 gene polymorphisms and uterine leiomyoma risk in Iranian women

Abstract

Uterine leiomyoma (UL) is the most common gynecological benign tumor with unknown etiology and pathogenesis. This case- control study was performed to investigate the association between CYP1B1gene polymorphisms with uterine leiomyoma in Iranian women. Polymorphisms CYP1B1 Arg48Gly, Ala119Ser, Leu432Val and Asp449Asp were genotyped by using polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) method in 300 premenopausal women with diagnosed UL (cases) and 200 healthy normal (controls). A significant difference was found for the C allele frequencies of the Leu432Val C>G polymorphism between the two groups (OR = 0.71, P = 0.04, 95 % CI = 0.48 – 1.03). However, no significant difference was found for the CYP1B1 Arg48Gly, Ala119Ser and Asp449Asp polymorphisms between the two groups (p>0.05). Our findings indicated that CYP1B1 Leu432Val CC genotype may be involved in susceptibility to UL in Iranian women.
