High-density genotyping of immune loci in Kawasaki disease and IVIG treatment response in European-American case-parent trio study

Abstract

  • © 2014 Macmillan Publishers Limited All rights reserved. Kawasaki disease (KD) is a diffuse and acute small-vessel vasculitis observed in children, and has genetic and autoimmune components. We genotyped 112 case-parent trios of European decent (confirmed by ancestry informative markers) using the immunoChip array, and performed association analyses with susceptibility to KD and intravenous immunoglobulin (IVIG) non-response. KD susceptibility was assessed using the transmission disequilibrium test, whereas IVIG non-response was evaluated using multivariable logistic regression analysis. We replicated single-nucleotide polymorphisms (SNPs) in three gene regions (FCGR, CD40/CDH22 and HLA-DQB2/HLA-DOB) that have been previously associated with KD and provide support to other findings of several novel SNPs in genes with a potential pathway in KD pathogenesis. SNP rs838143 in the 3′-untranslated region of the FUT1 gene (2.7 × 10-5) and rs9847915 in the intergenic region of LOC730109 BRD7P2 (6.81 × 10-7) were the top hits for KD susceptibility in additive and dominant models, respectively. The top hits for IVIG responsiveness were rs1200332 in the intergenic region of BAZ1A C14orf19 (1.4 × 10-4) and rs4889606 in the intron of the STX1B gene (6.95 × 10-5) in additive and dominant models, respectively. Our study suggests that genes and biological pathways involved in autoimmune diseases have an important role in the pathogenesis of KD and IVIG response mechanism.
