One common genetic marker wasidentified for the “IHD only” and “IHD and AH”phenotypes: rs4765623 in the SCARB1 gene; two common geneticmarkers, rs663048 in SEZ6L and intragenic rs6501455, wereidentified for the “IHD and AH” phenotype and a combination ofseveral diseases (syntropy); there were no common genetic markers for the“syntropy” and “IHD only” phenotypes. This evidence concerns the gene SEZ6L and myocardial ischemia.
