Abstract

The deletion D allele of the angiotensin-I converting enzyme (ACE) I/D gene variant is associated with higher ACE activity in Caucasians and previous studies in non-Caucasian samples have suggested an association between the D allele and type 2 diabetes (Type 2DM). The aim of this study was to compare the genotype distribution between Caucasian subjects with Type 2DM and nondiabetic Caucasian men. Genotype distribution was compared between 574 Caucasian subjects with Type 2DM, recruited from the UCL Diabetes and Cardiovascular Disease Study and 2413 non-diabetic Caucasian men, recruited from the second Northwick Park Heart Study. Within both samples, genotype distributions were in Hardy Weinberg equilibrium. The genotype distributions in those with Type 2DM compared to the non-diabetic men (II/ID/DD) was 18%/50%/32% vs. 23%/49%/27%, p = 0.004. In accordance with this, the frequency of the D allele was higher in those with Type 2DM (0.574 [0.55-0.60] vs. 0.519 [0.50-0.53], p = 0.001). On combining the two samples, the odds ratio (OR) for Type 2DM was significantly higher in D allele carriers compared to 11 subjects (OR = 1.55, p = 0.02, after adjustment for age, sex, BMI, blood pressure, and lipids). In those with diabetes, there was a significant association between genotype and a family history of diabetes. The odds ratio for a family history of diabetes in DD compared to 11 subjects was 1.52 [0.89-2.60], p = 0.03. This study clearly shows an association between the ACE I/D common gene variant and Type 2DM. (C) 2004 Elsevier Inc. All rights reserved.
