The association between cerebral infarction and angiotensin converting enzyme gene polymorphism in Binhai area Tianjin / 国际检验医学杂志

ABSTRACT

Objective To study the association between the cerebral infarction and the angiotensin converting enzyme (ACE) gene rs4646994 and rs35397082 polymorphisms in Binhai area ,Tianjin .Methods Gene sequencing and DNA electrophoresis were used for the detection of the ACE gene single nucleotide polymorphisms (SNPs)(rs4646994 and rs35397082) .53 samples from pa‐tients with acute cerebral infarction and 53 samples from healthy volunteers were used in our study .Serum sample were collected from each group and tested by ACE ELISA .Results There were only deletion type of rs35397082 SNP in both of the control and cerebral infarction group .In the control group ,the number of insertion type of rs4646994 was 45(84 .91% ) ,deletion type was 8(15 . 09% ) and in the patients group ,the number of insertion was 47(88 .68% ) and the deletion was 6(11 .32% ) .There was no signifi‐cant difference between the patients group and the healthy donors (P>0 .05) .The concentration of ACE in control group was high‐er than the patients with acute cerebral infraction (P<0 .05) .Conclusion There is no significant association between the ACE gene polymorphisms(rs35397082 and rs4646994) and cerebral infarction in Binhai area ,Tianjin .The different concentration of ACE is not caused by these two SNPs .In this study ,these two SNPs are not the are not the risk factors of the cerebral infarction in Tianjin based on our study .
