[Complex analsis of association of inflammation genes with myocardial infarction].
Carriage frequencies of alleles and genotypes of functionally important polymorphous loci of some inflammation genes: proinflammatory cytokines genes IL-6, LTA and TNF, anti-inflammatory cytokine gene TGFB1 and CC chemokine receptor 5 gene CCR5 were analyzed in the patients with myocardial infarction (MI) of Russian ethnic descent (199 cases) and in the control group of the same ethnic descent (142 controls). Complex analysis using APSampler algorithm revealed MI association with carriage of all polymorphous variants studied, as individual risk factors (insertion/deletion polymorphism of CCR5 and SNP G252A LTA) or only in combination with other alleles/genotypes. Carriage of bi- or triallelic combinations was associated with MI more significantly than carriage of any their subsets: single alleles or allele pairs. Protective triallelic combination d*CCR5 + 252G*LTA(+) -174C*Ll-6 was found to be most significant (p = 0.0006, OR = 0.23, CI = 0.090-0.56). Separate analysis of genetic susceptibility to MI for men and women displayed sexual dimorphism for CCR5 gene.
