Abstract:
Objective To investigate the association between MPO gene single nucleotide polymorphisms (SNP) loci (rs2333227,-643G/A) and clinical characteristics in Kawasaki disease (KD) in Han population in central China. Methods A case-control study was performed. Two hundred and thirty-seven children with KD and 249 normal children were recruited. The polymorphism distribution of SNP was detected using PCR-RFLP. The clinical data of children with KD were collected. Results The frequency of SNP loci (rs2333227) genotypes (GG, GA, AA) was signiifcantly different between children with KD and normal children (P=0.039), the allele frequency was also signiifcantly different between two groups (P=0.012), and the G allele was the risk factor. Compared with other genotypes, KD children with GG genotype had higher frequency in hand-foot edema (P=0.029). The SNP polymorphism was also associated with peritoneal effusion (P=0.028), however this SNP polymorphism was not associated with conjunctival hyperemia, oral mucosa lesions, and coronary artery lesion (P>0.05), also was not associated to imaging characteristics of hepatomegaly, splenomegaly, and lobular pneumonia (P>0.05). Conclusion The SNP loci (rs2333227) in MPO gene was associated with KD susceptibility, the G allele was a risk factor, and the SNP polymorphisms is associated with some clinical characteristic.
