Complex analysis by the APSampler algorithm revealed associations of MI with the carriership of all polymorphic variants either regarded as individual risk factors (insertion-deletion polymorphism of CCR5 and SNP G252A LTA) or in combination with other alleles or genotypes. The carriership of bi- or triallelic combinations was associated with MI more reliable than the carriership of any subsets: single alleles or allele pairs. The protective triallelic combination d*CCR5 + 252G*LTA + -174C*Il-6 was found to be the most significant (p= 0.0006, OR = 0.23, CI = 0.090-0.56). Separate analysis of genetic susceptibility to MI in men and women demonstrated sexual dimorphism for the CCR5 gene. human, Russians, myocardial infarction, inflammation, cytokines, DNA, genes, allelic polymorphism, polymerase chain reaction, APSampler |
