NFKB1 and myocardial infarction: Also, Boccardi et al. in a study of Italian population reported that NFKB1 -94 ATTG ins/del polymorphism plays a protective role against CAD development and showed that carriage of NFKB1-94 ATTG ins/del gene variant confers a lower susceptibility to myocardial infarction incidence which was inconsistent with the present study [22].
