Stroke is a major global disability cause, and genetic variables for multifactorial illnesses like stroke are crucial for precision medicine. The purpose of this study is to see if genetic variants in the MTHFR gene are associated with a higher risk of ischemic stroke among the Egyptian population. A case-control study was conducted at Mansoura University Hospital, involving 100 stroke patients and 150 healthy volunteers as the control group. Peripheral blood genomic DNA was isolated and single-nucleotide polymorphisms were genotyped using ARMS-PCR. The CT and TT genotypes of the C677T gene polymorphism exhibited substantial risks for having stroke disease [(OR 3.856; P ≤ 0.001); (OR 4.026; P ≤ 0.001), respectively]. The T allele was significantly more prevalent among patients compared to controls. (OR 2.517; (P = 0.001)). The over-dominant and dominant models demonstrated a substantial relationship between stroke groups at risk of developing stroke but not the Recessive model. An extensive connection was found between the MTHFR A1298C and stroke danger in three different inheritance models: dominant (CC + CA vs. AA), over-dominant (AA + CC vs AC), and allelic (C allele) (P < 0.001). A highly significant difference in blood pressure, total cholesterol, and triglycerides levels was found between patients and control. While there was no meaningful link discovered between genetic polymorphism with SBP, DBP, TG, LDL, VLDL among stroke group (P > 0.05 for each) except the CC genotype that was significantly associated with lower levels of TC and HDL when compared to CT + TT genotypes. The study evaluates a strong link among MTHFR mutations in genes and the probability to get stroke. The research significantly supports the use of MTHFR ((rs1801133) and (rs1801131) variations in stroke prediction.
中风是全球主要的残疾原因之一,而像中风这样的多因素疾病的遗传变量对于精准医学至关重要。本研究旨在探讨埃及人群中亚甲基四氢叶酸还原酶(MTHFR)基因中的遗传变异是否与缺血性中风的风险增加有关。采用病例对照研究方法,在曼苏拉大学医院进行,共纳入 100 例中风患者和 150 例健康志愿者作为对照组。提取外周血基因组 DNA,采用 ARMS-PCR 技术检测单核苷酸多态性。结果显示,C677T 基因多态性的 CT 和 TT 基因型与中风疾病有显著相关性[比值比(OR)分别为 3.856;P≤0.001;OR 为 4.026;P≤0.001]。与对照组相比,TT 基因型在患者中更为常见(OR 2.517;P=0.001)。此外,过度显性和显性模型显示,在有中风风险的患者中存在显著的相关性,但在隐性模型中不存在。MTHFR A1298C 与中风危险之间存在广泛的联系,在三种不同的遗传模型中:显性(CC+CA 与 AA)、过度显性(AA+CC 与 AC)和等位基因(C 等位基因)(P<0.001)。患者与对照组之间的血压、总胆固醇和三酰甘油水平有显著差异。虽然在中风组中未发现遗传多态性与 SBP、DBP、TG、LDL、VLDL 之间有显著相关性(P>0.05),但 CC 基因型与 CT+TT 基因型相比,TC 和 HDL 水平显著降低。本研究评估了 MTHFR 基因突变与中风发生概率之间的关系。该研究结果为 MTHFR (rs1801133 和 rs1801131)在中风预测中的应用提供了有力支持。
