Introduction: Preeclampsia is a severe multifactorial complication of pregnancy. Studies found associations between folate metabolism genes’ polymorphisms and preeclampsia. However, investigations in this field are limited among Asian populations. Thus, the study’s aim was to evaluate the prevalence of methionine synthase (MTR), methionine synthase reductase (MTRR), and methylenetetrahydrofolate reductase (MTHFR) genes’ polymorphisms among ethnic Kazakh women with preeclampsia. Methods: This was a retrospective study involving 4246 patients’ data for the period of 2018–2022. Identification of MTR, MTRR, and MTHFR genes’ polymorphism was performed via PR-PCR. Peripheral blood samples were obtained for the analyses. In total, 4246 patients’ data of Kazakh ethnicity with preeclampsia at >20 weeks gestational age who had undergone an investigation to identify polymorphisms of the folate metabolism pathway genes for the period of 5 years were included in this study. Results: The most common and prevalent mutation was the MTRR A66G polymorphism: 24.5% of all tested patients with preeclampsia had the MTRR A66G polymorphism. It was highest among the 35–39 age group participants. The second most prevalent was the MTHFR C677T polymorphism: 9% of women with preeclampsia had the MTHFR C677T mutation. It was highest among women aged 30–34. There was a rare association of the MTR A2756G mutation with preeclampsia among the study participants. Conclusions: The identified levels of MTRR A66G and MTHFR C677T polymorphisms among the study participants suggest the importance of evaluating MTRR and MTHFR polymorphisms in women with preeclampsia. The role of the MTR A2756G polymorphism in the development of preeclampsia needs to be further investigated.
