[The glutathione peroxidase 1 (GPX1) single nucleotide polymorphism pro198Leu: association with life span and coronary artery disease].

[Article in Russian]


In this study we genotyped polymorphism in GPX1 Pro198Leu (C > T) rs 1050450 in four groups: patients with coronary artery disease, long-livers - above 90 years, early died peoples (before 55 years) from cardiovascular diseases and Russian population as control group. We have found significant higher allele T frequency in men with coronary artery disease -34.84% (Chi2 = 5.228, p = 0.022; OR = 1.46) and in early died men from cardiovascular diseases--38.16% (Chi2 = 6.461, p = 0.011; OR = 1.69) compared with control men--26.8%. Moreover, significantly higher genotype TT frequency has been shown in patients with coronary artery disease and myocardial infarction before age 50--19.44% in comparison with control group--7.28% (Chi2 = 9.55, p = 0.002). The TT frequency in long-livers (4.39%) was the lowest and significantly different from coronary artery disease group--12.79% (Chi2 = 8.07, p = 0.0045) and from coronary artery disease subgroup with myocardial infarction before 50--19.44% (Chi2 = 14.49, p = 0.0001). Thus our results indicate that allele T (Leu) of GPX1 Pro198Leu (C > T) polymorphism is unfavorable for successful ageing. It predisposes to coronary heart disease, earlier myocardial infarction (before age 50) and earlier death (before age 55).
