Kawasaki disease (KD; OMIM 611775) is an acute vasculitis syndrome which predominantly affects small-and medium-sized arteries of infants and children. Epidemiological data suggest that host genetics underlie the disease pathogenesis. Here we report that multiple variants in the caspase-3 gene (CASP3) that are in linkage disequilibrium confer susceptibility to KD in both Japanese and US subjects of European ancestry. We found that a G to A substitution of one commonly associated SNP located in the 5′ untranslated region of CASP3 (rs72689236; P = 4.2 × 10-8 in the Japanese and P = 3.7 × 10-3 in the European Americans) abolished binding of nuclear factor of activated T cells to the DNA sequence surrounding the SNP. Our findings suggestthat altered CASP3 expression in immune effecter cells influences susceptibility to KD.
