Background and Aim: Recurrent spontaneous abortion (RSA) is the most common complication of pregnancy that refers to two or more miscarriages before the 20th week of pregnancy. HLA-G immunoglobulin molecule plays an important role in protecting the fetus against mother's immune system. The aim of this study was to investigate the association between rs1632943 and rs1736932 polymorphisms with recurrent spontaneous abortion in Northwest of Iran.
Materials and Methods: This case-control study included 100 women with history of RSA as our case group and 80 healthy women with one or more than one children as the control group. Genomic DNA was purified from their peripheral blood samples and their genotypes were determined by PCR-sequencing method. Using SPSS 16, statistical analysis was performed by chi-square test.
Results: In rs1632943 polymorphism the frequency of CC, CA and AA genotypes were 8%, 33% and 59% in the patient group and 16.25%, 43.75% and % 40 in the control group, respectively. Statistical analysis showed that AA genotype was associated with the recurrent spontaneous abortion (P = 0.005). In the rs1736932 polymorphism, the frequency of CC, CG and GG genotypes were 8%, 32% and 60% in the patient group and 17.5%, 41.25% and 41.25% in the control group, respectively. Statistical analysis showed that GG genotype was associated with the recurrent miscarriage (P = 0.005). Also, haplotype analysis showed that H1 haplotype (GA) is associated with the disorder.
Conclusion: Results of the study showed that rs1632943 and ra1736932 polymorphisms |
