CAT and myocardial infarction: Among the combinations obtained, a pairwise analysis of possible non-linear interactions between the identified combinations of alleles/genotypes was carried out, which showed synergistic interactions of the polymorphic variants CX3CR1*A/G and CASP8*I/I, MSRA*C and CRP*C, CAT*C/T and MSRA*C, CAT*C/T and CX3CR1*A contributing to the development of MI.
