Polymorphisms in angiotensin-converting-enzyme gene and progression of IgA nephropathy.

Author information

Renal Unit, Western Infirmary, Glasgow, UK.


We have investigated the influence of the functional insertion (I) and deletion (D) polymorphism in intron 16 of the gene for angiotensin-converting enzyme (ACE) in a retrospective study of 100 patients with IgA nephropathy. There was no difference in genotype frequency compared with normal subjects. However, patients homozygous for the D allele tended to present at an earlier age (medians: DD, 33; ID, 34; II, 42 years) and to require renal replacement therapy at a younger age (medians 37, 42, and 48 years, respectively). The rate of progression was significantly worse in patients homozygous for the D allele. The DD genotype is associated with increased severity of disease in patients with IgA nephropathy.
