Background. Parental chromosomal abnormalities as well as changes in genes encoding thrombophilic factors are common causes of recurrent abortions. One of the causes of thrombophilia is Factor II (F2) gene mutation (G20210A) and plasminogen activator inhibitor gene (PAI-1) polymorphism (4G/5G). Therefore, the present study aimed to investigate the frequency of chromosomal abnormalities and the association of thrombophilic gene polymorphisms in patients with abortion in northwestern Iran.

Methods. In the present case-control study, cytogenetic analysis of 60 couples with a history of recurrent abortions was performed by the standard 72-hour culture of lymphocytes and G-banding. The polymorphism (5G/4G) of PAI-1 gene and the mutation (G20210A) of F2 genes were evaluated using RFLP-PCR and ARMS-PCR molecular methods, respectively. The obtained data were analyzed using statistical software.

Results. No significant abnormalities affecting abortion were observed in cytogenetic studies; in the molecular study, the frequency of the 4G allele in patients and control groups were 54.2% and 33.3%, respectively; the frequency of 5G allele in the patients and control groups were 45.8% and 66.8%, respectively. The frequency of 5G/5G and 4G/5G genotypes is 25.0% and 41.6% in the patient group, and 55.0% and 23.3% in the control group, respectively. Also, the frequency of 4G/4G genotype in patients and controls were 33.3% and 21.6%, respectively.

Conclusion. The results of this study show that there is a significant relationship between the frequency of the 4G allele of the PAI-1 gene with susceptibility to recurrent abortions in northwestern women, while no was relationship between F2 gene mutation and recurrent abortions was observed.
