Relationship of the angiotensin-converting enzyme gene polymorphism to glucose intolerance, insulin resistance, and hypertension in NIDDM
Abstract
The deletion (D) allele of the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism has been shown to be associated with cardiovascular and renal diseases in diabetes mellitus, but the mechanism underlying this association is not known. In addition, recent studies of the effect of the ACE gene on blood pressure have yielded conflicting results. Therefore, we studied the association of the ACE gene I/D polymorphism with glucose intolerance and insulin resistance, and the contribution of this locus to genetic susceptibility to hypertension in non-insulin-dependent diabetic mellitus (NIDDM). We analysed the ACE genotype in 84 unrelated NIDDM patients with a known disease duration of less than 1 year and in 115 age- and sex-matched controls. The I/D polymorphism was determined by the polymerase chain reaction. There were no differences in ACE genotype distribution and allele frequencies between patients with NIDDM and nondiabetic controls. The frequencies of the D and I alleles in both groups were identical, viz., 0.65 and 0.35, respectively. The NIDDM patients with the DD genotype had significantly higher blood glucose levels in the oral glucose tolerance test than those with the other genotypes; the incr...Continue Reading
