Investigation on the distribution of prethrombotic state susceptibility genes in the population with poor pregnancy

Objective?To explore the distribution of prethrombotic state susceptibility gene polymorphisms in the population with a history of poor pregnancy. Methods?From December 2018 to June 2021, 410 women with a history of poor pregnancy and childbirth (research group) and 111 normal women (control group) were collected as the research subjects. EDTA anticoagulated whole blood of the two groups were collected，its genomic DNA were extracted，fluorescence quantitative PCR technology was used to detect the distribution of prethrombotic state susceptibility gene polymorphisms. Results?① There was no significantly difference in MTHFR A1298 C, PAI-1 5G/4G, FⅤ A1691G, FⅡG20210A gene polymorphisms between the two group (P>0.05);② There were significantly difference in the distribution of genotypes in MTRR A66G sites AA，AG，GG between the two group (P<0.05).③ There were significantly difference in the AA，AG，GG genotypes and the G, A allele frequencies at the C677T site of MTHFR between the two group (P<0.05). Conclusion?The prethrombotic state susceptibility gene MTRR A66G locus and MTHFR C677T locus polymorphisms are related to the history of adverse pregnancy and childbirth.
