[Association between gene polymorphism of CD40 gene and coronary artery lesion in Kawasaki disease].

ABSTRACT

OBJECTIVE: To study the association between two single nucleotide polymorphisms (rs4810485 and rs1535045 in CD40 gene) and Kawasaki disease (KD) in Han Chinese children. METHODS: A case-control study was performed on 184 children with KD and 206 normal controls. The polymorphisms of two SNPs in CD40 gene were detected using PCR-RFLP. RESULTS: There were no significant differences in the genotype distribution and allele frequency of SNP rs4810485 in CD40 gene between the KD and normal groups (P>0.05). The genotype distribution of SNP rs1535045 in CD40 gene in the KD group was significantly different from the control group (P<0.05). T allele of SNP rs1535045 was shown as a risk factor for development of KD (OR=1.592, 95%CI 1.182-2.144, P=0.004). There were no association between the polymorphisms of the two SNPs and coronary artery lesions (P>0.05). CONCLUSIONS: SNP rs1535045 may be associated with the development of KD in Han Chinese children, while SNP rs4810485 may not.
