[The frequency of allelic polymorphism of matrix Gla-protein gene in acute coronary syndrome patients].

Abstract

Allelic polymorphisms of matrix Gla protein (MGP) gene were determinated in 115 patients with acute coronary syndrome (ACS) and in 110 practically healthy people. It was shown that interrelation of major homozygotes, heterozygotes and minor homozygotes by T-138-->C MGP promoter polymorphism in patients with ACS were 59.8%, 32.7%, 7.5% and in control 58.7%, 36.7%, 4.6% (P>0.05 by X2-test); by G-7-->A polymorphism: 42.1%, 45.6%, 12.3% and 41.8%, 54.5%, 3.6% correspondingly (P<0.05); and by Thr83Ala exon 4 polymorphism: 42.6%, 43.5%, 13.9% compared to 43.9%, 45.9%, 10.2% in control (P>0.05). The obtained data show that MGP A/A variant of MGP promoter G-7-->A polymorphism is a risk factor of ACS in Ukrainian population. These data indicate also that the intensity of calcification influences atherosclerotic injury of coronary artery.
