Abstract: Objective To investigate the relationship between the polymorphisms of angiotensin Ⅱ receptor gene and the risk of primary aldosteronism (PA).Methods Polymerase chain reaction -restriction fragment length polymorphism (PCR -RFLP)was used to examine the 1 1 66A /C polymorphism of AT1 R gene and 1 675A /G poly-morphism of AT2R gene in 85 patients with PA and 1 00 healthy controls.Results There was no significant difference of AT1 R 1 1 66A /C genotypes (AA,AC,CC)and allele (A and C)frequency among patients and controls (χ2 =0.430,P =0.806).There was obvious difference of AT2R 1 675A /G genotypes (AA,AG,GG)and allele (A and G) frequency among two groups (χ2 =6.1 21 ,P =0.01 3).The G allele was higher than A allele in PA group (χ2 =6.767,P =0.009).Conclusion Homogenic mutation of 1 675A /G site in AT2R gene may be one of risk factors of PA.
