This study was conducted to investigate if polymorphisms in ORAI1/CRACM1, a gene downstream from ITPKC, are associated with KD susceptibility and clinical outcomes.
The involvement of the FCGR2A locus may have implications for understanding immune activation in Kawasaki disease pathogenesis and the mechanism of response to intravenous immunoglobulin, the only proven therapy for this disease.

the GC and CC genotypes of ITPKC gene SNP rs28493229 were overrepresented in KD patients (GG:GC:CC was 236:43:1, C allele frequency: 8.04%) than those in the controls (GG:GC:CC was 454:37:1, C allele frequency: 3.96%; OR: 2.23, P = 0.001).
Taken together, our results indicated that C-allele of ITPKC SNP rs28493229 is associated with the susceptibility and aneurysm formation in KD patients in a Taiwanese population.

A polymorphism of one such gene, ITPKC, a negative regulator of T cell activation, confers susceptibility to KD in Japanese populations and increases the risk of developing coronary artery abnormalities in both Japanese and U.S. children.
The aim of this study was to investigate if the single-nucleotide polymorphism (SNP) rs28493229 of the ITPKC gene is associated with susceptibility to KD or with CALs in Taiwanese children.
Firstly, genetic analysis of affected Japanese children identified ITPKC, 1,4,5-triphosphate 3-kinase C, a kinase involved in regulation of T-cell activation, to be significantly associated with susceptibility to and increased severity of Kawasaki disease.
In this review, we summarize the cumulative knowledge regarding KD, and then outline our hypothesis of the role ITPKC plays in KD susceptibility and our trial that aims toward the implementation of personalized medicine for KD.
ITPKC acts as a negative regulator of T-cell activation through the Ca2+/NFAT signaling pathway, and the C allele may contribute to immune hyper-reactivity in Kawasaki disease.

Six single-nucleotide polymorphisms (SNPs) in three loci were associated significantly with KD susceptibility (P<1.0 × 10<sup>-5</sup>), including the previously reported BLK locus (rs6993775, odds ratio (OR)=1.52, P=2.52 × 10<sup>-11</sup>).
These associations include ERAP1, CCR1-CCR3, STAT4, KLRC4, GIMAP4, and TNFAIP3 in Behçet's disease; BLK and CD40 in Kawasaki disease; SERPINA1 and SEMA6A in antineutrophil cytoplasmic antibody associated vasculitides; IL12B and FCGR2A/ FCGR2A in Takayasu arteritis; and CECR1 in a newly defined vascular inflammatory syndrome associated with adenosine deaminase (ADA2) deficiency.
Genetic studies have identified several susceptibility genes for KD and its sequelae in different ethnic populations, including FCGR2A, CD40, ITPKC, FAM167A-BLK and CASP3, as well as genes influencing response to intravenous immunoglobulin (IVIG) and aneurysm formation such as FCGR3B, and transforming growth factor (TGF) β pathway genes.
We report two new loci, one at BLK (encoding B-lymphoid tyrosine kinase) and one at CD40, that are associated with Kawasaki disease at genome-wide significance (P < 5 × 10(-8)).

<b>Results:</b> We analyzed patients' DNA for the SNPs in B lymphoid tyrosine kinase, CD40, and coatomer protein complex beta-2 subunit, which had been associated with KD by literatures.
Several susceptibility genes (e.g., ITPKC, CASP3, CD40 and ORAI) and chromosomal regions have been identified through genome-wide association and genome-wide linkage studies to have association with KD.
