GENETICS OF CORONARY ARTERY DISEASE IN FAMILIES
... Premature coronary artery disease (CAD) occurs most commonly in families with multiple affected members. Such families are enriched with genetic variants that contribute to CAD, and therefore represent an ideal population for identification of susceptibility genes that might contribute to better ris ...
