Abstract: 

Background: Various factors, such as genetic causes, anatomic abnormalities of the uterus, infectious diseases, coagulative disorders, and endocrinological and immunological diseases, might influence recurrent pregnancy loss (RLP). This study aimed to evaluate the prevalence and frequency of the FII G20210A, FVL G1691A, and MTHFR C677T polymorphisms in Sudanese women with RPL.
Methods and Results: This descriptive cross-sectional study involved 100 women with a history of 3 or more RPLs (the case group) and 94 healthy multiparous women without pregnancy complications (the control group). DNA was extracted from peripheral blood samples. The study of the FII G20210A, FVL G1691A, and MTHFR C677T polymorphisms was performed by PCR and RFLP analysis.
For the FII G20210A, the genotype distribution in the case group and control group was as follows: GG=97.0%, GA=3.0%, AA=0% and GG=94.0%, GA=0%, AA=0%, respectively. In the case group, the allelic distribution was as follows: G=98.5%, A=1.5%. In the control group, the A allele was absent, and the frequency of the G allele was 100%. For the MTHFR C677T, the genotypic and allelic frequencies in the case group were 97%, 3%, and 0%, respectively, for the CC, CT, and TT genotypes, and 98.5% and 1.5%, respectively, for the C and T alleles. In the control group, the genotype distribution was as follows: CC-100% CT-0%, TT-0%; the T allele was absent, and the frequency of the C allele was 100%. For the FVL G1691A, the genotype distribution in the case group and control group was as follows: GG=92.0%, GA=8.0%, AA=0% and GG=93.6%, GA=6.4%, AA=0%, respectively. For G and A alleles, the frequencies were 96.0% and 4.0%, respectively, for the case group, and 96.8% and 3.2%, respectively, for the control group. Our analysis did not reveal a significant positive association between the MTHFR C677T, FII G20210A, and FVL G1691A polymorphisms and the risk of RPL across the dominant model, multiplicative model, and a comparison of the frequencies of the heterozygous and homozygous dominant genotypes. 
Conclusion: The research findings suggest that the MTHFR C677T, FVL G1691A, and FII G20210A variants do not significantly contribute to the increased susceptibility to RPL in this specific population of Sudanese women. Continued scientific inquiry is crucial for developing more nuanced and personalized strategies for the diagnosis and prevention of RPL, ultimately improving women's reproductive health.
