ABSTRACT
Objective To investigate the relationship between the insertion/deletion(I/D) polymorphism of the angiotensin convcer-(ting) enzyme(ACE) gene and congenital heart disease(CHD) and to quest the predisposing gene of congenital heart disease by analyzing the polymorphism of the ACE gene in patients with CHD.Methods Sixty-eight patients with CHD were served as observing group,sixty-four patients without CHD as control group.We drew DNA of leukocyte from blood by the method of saturation phenol and chloroform and we amplified the ACE gene using the DNA polymerase chain reaction technique.The amplification products were employed electrohoresis in 2% sepharose.the polymorphism of the angiotensin converting enzyme gene was analyzed under ultraviolet lump.Results In the obser-(ving) group,the genotype distribution frequency of the ACE was II in 12(17.65%),DD in 32(47.06%) and ID in 24(35.29%),and in the control group,it was II in 20(31.25%),DD in 10(15.63%) and ID in 34(53.12%).Conclusions The study result clarifies that CHD has close correlation to the polymorphism of the angiotensin converting enzyme gene.The relative risk of DD genotype is higher than that of the others,and DD genotype possibly is the predisposing genotype of CHD D allele perhaps is the susceptibility gene of CHD.
