Several men were examined for association between restriction fragment length polymorphism (RELP) Xba I (exon 26) number of tandem repeats in 3'-hypervariable region of the apolipoprotein-B gene and serum levels of cholesterol and triglyceride. These two types of polymorphism were studied. An association of the Xba I site and alleles containing more repeats in the 3'-hypervariable region with higher cholesterol and triglyceride was observed. 32 patients with CHD aged 24-56 years were examined. All the patients are males with clinical picture of CHD (stable angina pectoris of II-III functional classes) and dyslipoproteinemia of II a, II b and IV types by D. S. Fredrickson. Xba-I polymorphism of apo-B gene was detected by DNA polymerase reaction method. The following Xba-I genotypes were distinguished: X1X1 (absence of Xba I site); X1X2 (heterozygosity on Xba I site) and X2X2 (homozygosity on Xba-I site). Lipantil (fenofibratte) was prescribed in a dose of 300 mg daily after meals (100 mg three times a day). Data obtained show that DNA polymorphism of apo-B gene not only influences plasma lipids concentration but also determines effectiveness of hypolipidemic therapy. Hypolipidemic effect of lipantil depends on Xba-I site presents in apo-B gene and is significantly expressed in homozygous patients with X1X1 genotype. |
