To determine whether the Factor V (1691G/A), Factor V HR2 (4070A/G), Prothrombin (20210G/A), PAI-1 (-675 I/D, 5G/4G), ACE (intron 16 I/D), Factor VII (Gln353Arg), Factor XIII (Val34Leu), β-fibrinogen (-455G/A), Glycoprotein Ia (807C/T), tPA (intron 8 D/I) gene mutations could be risk factors for recurrent pregnancy loss (RPL).
Genotyping of thrombophilic gene mutations were carried out by amplification Refractory Mutation System-PCR (ARMS-PCR) method after DNA extraction.
We found that the mutant allele frequencies of Factor V (1691G/A), Factor V HR2 (4070A/G), Prothrombin (20210G/A), PAI-1 (-675 I/D, 5G/4G), Factor XIII (Val34Leu) and β-fibrinogen (-455G/A) were more seen in the case group compared with the healthy control; However, the difference between the two group is not statistically significant (p > 0.05). Whilst the mutant allele frequencies of other studied genes were lower in the case in comparison to the fertile control women (p > 0.05).
Taken together, our data has shown that the prevalence of thrombophilic gene mutations was similar in women with RPL and healthy controls. Therefore, it appears that further studies on large-scale population and other genetic variants will be needed to conclusively find candidate genes for RPL unknown etiology in the future.
确定凝血因子 V(1691G/A)、凝血因子 V HR2(4070A/G)、凝血酶原(20210G/A)、纤溶酶原激活物抑制剂-1(-675I/D、5G/4G)、血管紧张素转换酶(内含子 16 I/D)、凝血因子 VII(Gln353Arg)、凝血因子 XIII(Val34Leu)、β-纤维蛋白原(-455G/A)、糖蛋白 Ia(807C/T)、组织型纤溶酶原激活物(tPA)(内含子 8 D/I)基因突变是否为复发性妊娠丢失(RPL)的危险因素。
通过聚合酶链反应-扩增受阻突变系统(PCR-ARMS)方法提取 DNA 后,对易栓症基因突变进行基因分型。
我们发现,与健康对照组相比,病例组凝血因子 V(1691G/A)、凝血因子 V HR2(4070A/G)、凝血酶原(20210G/A)、纤溶酶原激活物抑制剂-1(-675I/D、5G/4G)、凝血因子 XIII(Val34Leu)和β-纤维蛋白原(-455G/A)的突变等位基因频率更高;然而,两组之间的差异无统计学意义(p>0.05)。而其他研究基因的突变等位基因频率在病例组中低于生育对照组(p>0.05)。
综上所述,我们的数据表明,RPL 患者与健康对照组的易栓症基因突变发生率相似。因此,未来可能需要对更大规模的人群和其他遗传变异进行进一步研究,以确定 RPL 未知病因的候选基因。
