High incidence of angiotensin I converting enzyme genotype II in Kawasaki disease patients with coronary aneurysm.
A 287 base pair insertion/deletion polymorphism in intron 16 of the angiotensin I converting enzyme (ACE) gene was examined by polymerase chain reaction in 36 Kawasaki disease patients (16 without coronary aneurysm, 20 with coronary aneurysm). A polymorphism in the ACE gene was characterized by three genotypes: two D alleles (genotype DD), two I alleles (genotype II), and heterozygous allele (genotype DI). Genotype II was found in 65% of the patients with aneurysm and 12.5% of those without aneurysm (P < 0.01, odds ratio 13.0, 95% confidence intervals).


CONCLUSIONS
Patients with Kawasaki disease and coronary aneurysm more often than expected had the genotype II suggesting that reactions induced by the type of ACE polymorphism predispose to coronary aneurysm formation.
