概括
甲基酸酸减少酶 (MTHFR) 基因中的遗传变异与埃及人的缺血性中风风险增加有关. 特定的MTHFR基因突变显著预测中风概率,支持它们在风险评估中的使用.
科学领域:
- 遗传学 是一个遗传学.
- 神经学 神经学
- 精准医学是一门精准的医学.
背景情况:
- 卒中是全球残疾的主要原因之一.
- 遗传因素在诸如中风等多因素疾病中起着至关重要的作用,为精准医学策略提供了信息.
- 甲基四叶酸减少酶 (MTHFR) 基因与叶酸代谢有关,并已被研究其在各种健康状况中的作用.
研究的目的:
- 调查MTHFR基因中的遗传变异与埃及人口中缺血性中风风险之间的关联.
- 确定特定的MTHFR基因多态 (C677T和A1298C) 是否是中风的危险因素.
- 探索这些遗传变异与中风患者的临床参数之间的关系.
主要方法:
- 在曼苏拉大学医院对100名中风患者和150名健康对照进行了病例对照研究.
- 从外围血液中提取基因组DNA,并在MTHFR基因 (C677T和A1298C) 的单核酸多态 (SNP) 中使用放大阻断突变系统-聚合酶链反应 (ARMS-PCR) 进行基因定型.
- 统计分析,包括几率比率 (OR) 和置信区间,用于评估不同遗传模型下的基因型,等位基因和中风风险之间的关联.
主要成果:
- MTHFR C677T多态的CT和TT基因型与中风风险增加显著相关 (分别为OR3.856,P≤0.001;OR4.026,P≤0.001).
- 在中风患者中,MTHFR C677T的T等位基因更为普遍 (OR 2.517,P=0.001).
- 对于MTHFR A1298C,主导模型和超主导模型都显示出与中风风险的显著关联 (P<0.001),而衰退模型则没有. 与CT+TT基因型相比,CC基因型与较低的总胆固醇和HDL水平有关.
结论:
- 这项研究表明,MTHFR基因突变 (rs1801133和rs1801131) 与埃及人群中患缺血性中风的风险之间存在强烈联系.
- 这些MTHFR基因变异,特别是C677T和A1298C,可以成为预测中风的有价值标记.
- 这些发现支持将MTHFR基因定型纳入个人化医学方法,以评估中风风险.

Genome-wide Association Studies-GWAS
13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
