Plasminogen activator inhibitor-1 4G/5G polymorphism and susceptibility to endometriosis in the Italian population

Research output: Contribution to journalArticle

Abstract

Objectives: Some controversy exists for the potential association of the plasminogen activator inhibitor-1 (PAI-1) gene polymorphism 4G/5G and susceptibility to endometriosis. To clarify this issue, we have examined the prevalence of this polymorphism in a case-control study in the Italian population. Study design: The PAI-1 4G/5G polymorphism was evaluated in n = 368 reproductive year aged Caucasian women who underwent gynaecological laparoscopy for chronic pelvic pain, infertility, ovarian cysts and myomas. A second group of controls included n = 329 normal subjects. Results: The 697 women enrolled were divided as follows: the endometriosis group (n = 204), the gynaecological control group (n = 164) and the general population control group (n = 329). No statistical significant differences emerged between endometriosis patients and gynaecological controls with regard to the allele frequencies and co-dominant and dominant models of genotype distribution. A borderline statistical difference was only observed for the recessive model of inheritance in which, contrary to previous findings, the PAI-1 4G/4G genotype seems to be less linked to the disease development. Conclusion: The findings reported herein do not support the previously reported data indicating a greater susceptibility to endometriosis in patients harbouring the PAI-1 4G/5G and 4G/4G genotypes and exclude a significant role of polymorphism in endometriosis development.
