Polymorphism of the promoter region of the angiotensinogen gene and the gene for angiotensin I-converting enzyme in arterial hypertension and cardiovascular disease of the Kazakh ethnic group

Polymorphism of the promoter region of the angiotensinogen gene (ATG) and an angiotensin I-converting enzyme gene (ACE) insertion/deletion (I/D) polymorphism were studied in three different groups of Kazakhs (control group, patients with cardiovascular disease (CAD) and patients with arterial hypertension (AH)) using three methods. A comparative analysis of the distribution of genotype and allele frequencies was conducted.
