Analysis of Gene Complexes Predisposing to Coronary Atherosclerosis

Analysis of Gene Complexes Predisposing to Coronary Atherosclerosis The following seven polymorphic marker loci of genes responsible for predisposition to coronary atherosclerosis (CAS) were studied: the ACE locus responsible for angiotensin-converting enzyme insertion/deletion polymorphism for the presence or absence of the Alu insertion in the gene; the F13,PLAT, and APOA1 loci, controlling the clotting factor 13, plasminogen-activating tissue factor, and apolipoprotein A, respectively; the MTHFR and AGT polymorphic loci responsible for point mutations in methylenetetrahydrofolate reductase and those in angiotensinogen, respectively, and the NOS3 locus controlling the number of tandem repeats in the nitric oxide synthase gene. These loci are located on different chromosomes and encode products involved into various metabolic pathways leading to CAS. In the populations studied, significant differences between healthy subjects and patients predisposed to cardiovascular diseases were revealed with regard to the above seven markers. The 174M allele (T174M polymorphism in the AGT gene) was significantly associated with coronary atherosclerosis. It was found that specific gene combinations are involved in the CAS development and determine variation in the pathogenetically important quantitative traits. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The following seven polymorphic marker loci of genes responsible for predisposition to coronary atherosclerosis (CAS) were studied: the ACE locus responsible for angiotensin-converting enzyme insertion/deletion polymorphism for the presence or absence of the Alu insertion in the gene; the F13,PLAT, and APOA1 loci, controlling the clotting factor 13, plasminogen-activating tissue factor, and apolipoprotein A, respectively; the MTHFR and AGT polymorphic loci responsible for point mutations in methylenetetrahydrofolate reductase and those in angiotensinogen, respectively, and the NOS3 locus controlling the number of tandem repeats in the nitric oxide synthase gene. These loci are located on different chromosomes and encode products involved into various metabolic pathways leading to CAS. In the populations studied, significant differences between healthy subjects and patients predisposed to cardiovascular diseases were revealed with regard to the above seven markers. The 174M allele (T174M polymorphism in the AGT gene) was significantly associated with coronary atherosclerosis. It was found that specific gene combinations are involved in the CAS development and determine variation in the pathogenetically important quantitative traits.
