title: Frequency of a deletion polymorphism in the gene for angiotensin converting enzyme is increased in African-Americans with hypertension.
abstract: In white populations, a deletion polymorphism in the gene for angiotensin converting enzyme (ACE) appears to be associated with increased risk for myocardial infarction but not for hypertension. In a population-association study in African-Americans, we compared the frequency of the ACE deletion polymorphism in subjects with hypertension versus those with normal blood pressure. The frequency of the ACE deletion allele was greater in African-Americans with hypertension than in those with normal blood pressure (P < 0.05). These findings raise the possibility that in some patient subgroups, sequence variation in or near the ACE gene may contribute to the risk for hypertension.
