%X Background: The vascular endothelial growth factor (VEGF) polymorphism is associated with preeclampsia since its abnormal expression plays an important role in vasculogenesis in placenta formation. Thus, this study is aimed at analyzing the association between VEGF +936C/T polymorphism and the risk of preeclampsia. Methods: To assess the causal relationship, a hospital-based cross-sectional analytical study was carried out among 204 Myanmar pregnant women during the period of January 2018-September 2020. For data collection, a pretested, structured questionnaire was used. Blood samples were collected after obtaining consent, and then we studied the extracted gene by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The Statistical Package for Social Sciences version 18.0 was used for data management and analysis. Results: The genotype CT variant among preeclamptic women was more than that of non-preeclamptic women (26.5% vs. 18.6%), but not significant (p = 0.180). The risk of preeclampsia among women with CT genotypes was 1.57 times higher than that of women with CC genotypes (OR (95%CI) = 1.57 (0.81, 3.06), p = 0.180). The minor allele frequency of the T allele was 15.2% in preeclamptic women and 9.3% in normal pregnant women. The risk of preeclampsia among T allele carriers is 1.49 times (95%CI = 0.80, 2.77) more than that of C allele carriers (p = 0.211). Among the preeclamptic pregnant women, the frequency of the CT genotype was 26.3% in the severe preeclamptic group and 26.9% in the mild preeclamptic group, while the frequency of the T allele was 13.2% and 13.5%, respectively. The frequency of either CT genotype or T allele was more or less the same in both groups, and there was no association between VEGF C/T polymorphism and the severity of preeclampsia. After logistic regression analysis on VEGF genotype and clinical parameters such as age, maternal body mass index (BMI), and neonatal birth weight, the risk of preeclampsia was 2.1 times higher in pregnant women with CT genotype compared to CC genotype (adjusted OR, 2.1; 95% CI, 0.9-4.5, p value -0.057). Conclusion: There was no significant association between VEGF +936C/T polymorphism (rs3025039) and preeclampsia among Myanmar pregnant women. However, the findings of this study highlighted that individuals carrying either the CT genotype or the T allele are at a heightened risk of developing preeclampsia. Furthermore, it suggests a potential impact of the gene on the occurrence of preeclampsia, yet the data lacks sufficient evidence to establish statistical significance.
