摘要: |
目的扫描肾素基因发现新的多态性,探讨新多态性与原发性高血压相关性。方法运用聚合酶链反应-单链构象多态性(PCR-SSCP)方法,对肾素基因外显子4—8进行扫描,以发现新的多态性;在日本人212例原发性高血压(essential hypertension,EH)者和209例正常血压(normotension,NT)者中进行病例对照研究。结果PCR—SSCP法发现外显子8上游第18碱基对处内含子7区域可变数目串联重复序列(VNTR),DNA测序确定此多态性为重复7—12次的TCTG。病例对照研究显示VNTR基因型频率在原发性高血压和正常血压组中无显著性差异。结论本文发现的肾素基因新的VNTR多态性与原发性高血压无相关性。 |
