Abstract
Kawasaki disease (KD) is an acute vasculitis syndrome of unknown etiology that frequently affects small to medium size arteries. C-C chemokine receptor 5 (CCR5) is a chemokine receptor that binds C-C chemokines. This study investigated the association of the CCR5 (-2135C/T) polymorphism with KD in Korean children. The study population consisted 189 Korean children with KD and 194 Korean children with congenital heart disease (CHD). CCR5 (-2135C/T) polymorphism genotypes were determined using the single-base extension method. The allele frequencies of the CCR5 (-2135C/T) polymorphism differed significantly between CHD children and KD children (-2135T/T, 16.75% vs. 30.05%, aOR 2.14, 95% CI 1.31-3.51). The tested laboratory parameters differed significantly between the KD and CHD groups. The development of coronary artery aneurysm in KD patients was not associated with the CCR5 polymorphism. Our findings suggest that the T allele at the CCR5 (-2135C/T) polymorphism might be associated with the development of KD in Korean children but does not appear to be associated with the development of coronary artery aneurysm.
