Relation between the angiotensin II type 2 receptor polymorphism and essential hypertension in men / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To identify single nucleotide polymorphisms (SNP) of the angiotensin II type 2 receptor (AGTR2) gene, and to determine whether the AGTR2 polymorphisms are associated with essential hypertension in a male Chinese population.</p><p><b>METHODS</b>Direct DNA sequencing was performed in 20 subjects. 96 male hypertensive patients and 107 normal controls were included to assess the contribution of the SNP of AGTR2 gene to hypertension.</p><p><b>RESULTS</b>Seven SNP of the AGTR2 gene were identified, of which 4 were reported for the first time. A case-control study including two polymorphisms (A1675G and T1334C) showed a significant increase in the A1675 allele frequency among male hypertensive subjects as compared with normotensive subjects (49.0% vs 34.6%, P < 0.05).</p><p><b>CONCLUSION</b>The AGTR2 A1675G polymorphism might be involved in the development of essential hypertension in male Chinese.</p>
