In a recent genome-wide association analysis of a total of 915 children with Kawasaki disease and 4553 controls in the Korean population, the susceptibility locus for the disease was identified by Kim et al. [39] to be NMNAT2 on chromosome 1q25.3 (rs2078087) and the human leukocyte antigen (HLA) region on chromosome 6p21.3 (HLA-C, HLA-B, MICA, and HCP5 with rs9380242, rs9378199, rs9266669, and rs6938467, respectively). This evidence concerns the gene HCP5 and Kawasaki disease.
