The Associated of the Risk of IVIG Resistance in Kawasaki Disease with ZNF112 Gene and ZNF180 Gene in a Southern Chinese Population

Abstract

Background Kawasaki disease (KD) was one of the most common primary vasculitis. IVIG resistance was associated with an increased risk of coronary artery aneurysm. Accumulating evidences demonstrated that inflammatory gene polymorphisms might play important roles in IVIG resistance, and zinc finger proteins were closely related to immune inflammation regulation, but the effect of ZNF112 /rs8113807 and ZNF180 /rs2571051 on IVIG resistance in KD patients has not been reported. Methods A total of 996 KD patients were recruited, and the assay of TaqMan-real-time polymerase chain reaction was used for ZNF112 /rs8113807 and ZNF180 /rs2571051 genotyping. Odds ratio (OR) and 95% confidence interval (CI) were calculated for estimating the relationship between the polymorphisms of the both SNPs ( ZNF112 /rs8113807 and ZNF180 /rs2571051) and the risk of IVIG resistance. Results Both of the ZNF112 /rs8113807 CC/TC genotype and the ZNF180 /rs2571051 TT/CT genotype increased the risk of IVIG resistance in KD (rs8113807: CC vs TT: adjusted OR = 1.83, 95% CI = 1.06–3.16, p = 0.0293; CC/TC vs TT adjusted: OR = 1.49, 95% CI = 1.10–2.02, p = 0.0094. rs2571051: TT vs CC adjusted: OR = 2.64, 95% CI = 1.62–4.29, p < 0.0001; TT/CT vs CC adjusted: OR = 2.14, 95% CI = 1.37–3.37, p = 0.0009; TT vs CC/CT adjusted: OR = 1.66, 95% CI = 1.22–2.27, p = 0.0014). Furthermore, the combinative analysis of risk genotypes in ZNF112 /rs8113807 and ZNF180 /rs2571051 showed that patients with two unfavorable genotypes were more likely to increase risk of IVIG resistance than those who carried with zero or one unfavorable genotypes (adjusted: OR = 1.68, 95% CI = 1.24–2.27, p = 0.0008). Conclusion Our findings enriched the genetic background of IVIG resistance risk in the KD development and suggested that the ZNF112 /rs8113807 C-carrier and the ZNF180 /rs2571051 T-carrier were associated with increased risk of IVIG resistance in KD patients in Chinese southern population.

Genome-wide association study identifies several loci for HEV seropositivity

“… 26 ZNF112 gene, on the other hand, has been linked to immunoglobulin resistance in Kawasaki Disease (KD) possibly due to its regulatory contribution to inflammation. 27 Importantly, KD could be triggered by various infectious agents in genetically susceptible individuals. 28 Still, the role of PRDM15 and ZNF112 in the immune response to infections has never been studied.…”
