The IL1B -511 T > C polymorphism may serve as important risk factor for recurrent miscarriage while the IL6 -634C > G polymorphism may protect against the risk of recurrent miscarriage.
No significant differences were observed between the distributions of IL-1beta or IL-1 receptor antagonist gene alleles in either the recurrent miscarriage group as a whole or when divided according to the cause of recurrent miscarriage compared with controls, which suggests that variation in the IL-1 receptor antagonist gene and IL-1beta genes individually does not play a role in susceptibility to recurrent miscarriage.
Polymorphisms of the angiotensinogen gene, the endothelial nitric oxide synthase gene, and the interleukin-1beta gene promoter in women with idiopathic recurrent miscarriage.
The IL1B -511 T > C polymorphism may serve as important risk factor for recurrent miscarriage while the IL6 -634C > G polymorphism may protect against the risk of recurrent miscarriage.
The CYP1A1*2A polymorphism was found to have significant association with chronic obstructive pneumonopathy (p=0.045), peripheral circulatory problems (trend p=0.042), arteritis (p=0.022), allergies (trend p=0.046), hemorrhoids (trend p=0.026), allergic dermatitis (p=0.0016) and miscarriages (p=0.012).
Genotype distribution at an SNP (rs37389) in the prolactin receptor gene (P = 0.03), and allele distributions at an SNP (rs41423247) in the glucocorticoid receptor gene (P = 0.04) and an STR polymorphism in the estrogen receptor β gene (P = 0.03) were associated with recurrent miscarriage.
Compared to the ACE II genotype, DD and ID were both associated with increased risk of recurrent miscarriage (OR DD versus II=1.81, 95% CI 1.23-2.66, P=0.003; OR ID versus II=1.50, 95% CI 1.25-1.80, P<0.001).
Polymorphism in HABP2 showed no significant difference in women with recurrent miscarriage compared to fertile women, except for rs1157916 minor A allele that was more prevalent among RM patients (p = 0.058).
Factor V Leiden and prothrombinG20210A polymorphisms as risk factors for miscarriage during a first intended pregnancy: the matched case-control 'NOHA first' study.
This is the first report on VEGF gene polymorphisms in women with recurrent miscarriage, demonstrating that the -1154G/A VEGF gene polymorphism is associated with idiopathic recurrent abortions.
There was no difference in the distribution of Factor V Leiden (P=1.000), FII G20210A (P=0.652), and MTHFR C677T (P=0.869) between patients with two and three or more miscarriages, whereas MTHFR A1298C was more common among patients with two miscarriages (P=0.017).
The prevalence of FVL, FIIG20210A and MTHFR C677T was compared in 108 women with three or more pregnancy losses either exclusively in the first trimester, or mixed first and second trimester losses, with the prevalence found in 82 fertile parous control women without miscarriages.
We determined (i) the prevalence of three thrombophilic mutations [factor V Leiden (FVL), prothrombin G20210A (PTG) and methylenetetrahydrofolate reductase (MTHFR) C677T] amongst 357 Caucasian couples with RM and 68 parous Caucasian couples with no history of miscarriage and (ii) the prospective outcome of untreated pregnancies amongst couples with RM in which either partner carried a thrombophilic mutation.
To investigate the role of HLA-G polymorphism in this process and whether the HLA-G genotype is associated with an increased risk for a subsequent miscarriage, 69 women with three or more recurrent spontaneous abortions (RSA) and 146 fertile control women were genotyped for the HLA-G locus in this study.
