Among the studied genetic markers, 13 were associated with the “IHD and AH” phenotype(Table 2).Two of them are missense substitutions (rs2076530 in the BTNL2 geneand rs663048 in the SEZ6L gene), four are variants in introns (rs763317in EGFR, rs7794745 in CNTNAP2, rs4765623 inSCARB1, rs4430796 in HNF1A), and six arelocated in intergenic regions (rs801114, rs10499194, rs13207033, rs2398162,rs6501455, and rs1160312). The gene discussed is HNF1A; the disease is myocardial ischemia.
