Although disproportionate CHD survival for KIF6 Trip719Arg carriers is suggested by their 50% greater risk for recurrent myocardial infarction, we currently do not have direct evidence for a difference in fatality following cardiovascular events between 719Arg carriers and noncarriers, nor are we aware of other genetic variants that are associated with increased fatality after cardiovascular event. Here, KIF6 is linked to myocardial infarction.
