Angiotensin-converting enzyme and regulation of blood pressure in a large Australian family.
1. Animal studies have implicated the angiotensin-converting enzyme (ACE) gene as an inherited risk factor contributing towards elevation of blood pressure. 2. A polymorphism of the ACE gene, involving the presence or absence of a 287 base pair (bp) segment within the gene region, was assessed for association with high blood pressure in a large, multigeneration Australian family. The association of these alleles with hypertension in unrelated individuals was also examined. 3. There was no evidence to link the ACE gene and high blood pressure in the large family. Similarly, there was no significant association between this gene and high blood pressure in the population tested. As has been reported previously, plasma levels of the enzyme were associated with genotype. These results suggest that this gene is unlikely to be a major risk factor for hypertension in this group.
