Study is devoted to "genes for mitochondria"--genes of mitochondrial genome and mitochondrial DNA polymerase gamma gene (POLG1). We compared frequencies of polymorphisms in mitochondrial DNA and in POLG1 between healthy individuals and patients with arterial hypertension, as well as between patients with and without left ventricular hypertrophy. We did not discover significant differences of distribution of C allele of MspI-polymorphism in POLG1 in studied group. We have shown higher prevalence of mitochondrial haplogroup H of mtDNA in patients without left ventricle hypertrophy (OR = 0.42; 95% CI 0.17-0.98; p = 0.043), while compared with patients having this complication. Haplogroup T was more frequently detected in patients with left ventricle hypertrophy (OR = 6.16; 95% CI 1.17-9.74; p = 0.018). This result suggest implication of mitochondrial DNA in hypertension-induced left venticular hypertrophy.
该研究致力于“线粒体基因”——线粒体基因组基因和线粒体DNA聚合酶γ基因(POLG1)。我们比较了健康个体与动脉高血压患者之间,以及有和没有左心室肥厚的患者之间线粒体DNA和POLG1基因多态性的频率。在研究组中,我们未发现POLG1中MspI多态性的C等位基因分布存在显著差异。我们发现,与有左心室肥厚并发症的患者相比,没有左心室肥厚的患者中mtDNA的线粒体单倍群H更为常见(OR = 0.42;95% CI 0.17 - 0.98;p = 0.043)。单倍群T在有左心室肥厚的患者中更频繁被检测到(OR = 6.16;95% CI 1.17 - 9.74;p = 0.018)。这一结果表明线粒体DNA与高血压引起的左心室肥厚有关。
