Association between a Marker on Chromosome 9 and Acute Coronary Syndrome Confirmatory Study on Czech Population
Myocardial infarction (MI) is the leading cause of death in industrialized countries. All the classical risk factors for MI are responsible for approximately 50 % of MI cases. Attention has therefore recently been attracted to those genetic variants that are not associated with conventional risk factors. One of them is the marker rs10757274 in the “genefree” zone on chromosome 9, which has been repeatedly recognized as a risk factor for development of MI in Western populations. We analysed the relationship between the rs10757274 variant on chromosome 9 and risk of the acute coronary syndrome (ACS) in Czech population. The rs10757274 (A > G) variant was successfully analysed (CR = 99.4 % for patients and 98.4 % for controls) by PCR-RFLP in consecutively examined 1,046 men and 281 women with ACS (age below 65 years) and in population-based controls – 1,162 men and 1,355 women (aged up to 65 years). ANOVA and χ2 were used for statistical analysis. We confirmed that GG homozygotes are more frequent (codominant model of analysis) among patients with myocardial infarction than in the control group both inmen(28.5%vs.22.0%,P=0.0001,OR1.73,95% CI 1.36–2.19) and women (32.0 % vs. 24.6 %, P = 0.02, OR 1.62, 95 % CI 1.13–2.34). However, rs10757274 polymorphism was not associated with the classical risk factors either in control population or in ACS patients. We conclude that the rs10757274 variant at 9p23.1 is an important genetic risk factor for ACS development in the Czech population.
