ABSTRACT
Objective To investigate whether single nucleotide polymorphisms(SNPs)in the ABCC4(rs7320375,rs7329490,rs7986087),FCGR2A(rs1801274)and BLK(rs2254546)region could be susceptibility locus for Kawasaki disease(KD)in children from southern China.Methods This study was performed as a case-control study.The samples,92 individuals with KD and 194 healthy controls from southern China,were collected at Guangzhou Women and Childrens′Medical Center from October,2013 to November,2015,and the SNPs were genotyped by using the Sequenom MassArray system.The genotype distribution and allele frequency of the SNPs were analyzed using chi-square test and Fisher′s exact test.Results The genotype distribution of FCGR2A(rs1801274)in patients with KD were as follows: GG 4.3%(4/92),AG 33.7%(31/92),AA 62%(57/92),correspondingly in healthy controls were GG 48.5%(94/194),AG 41.2%(80/194),AA 10.3%(20/194)respectively,and a significant difference was found between KD patients and controls(x2=98.17,P=0.000).A allele frequency of FCGR2A(rs1801274)in KD patients(78.8%,145/184)was higher than that in controls(30.9%,x2=0.120,P=0.000).The genotype distribution of BLK(rs2254546)in patients with KD were as follows: GG 67.4%(62/92),AG 28.3%(26/92),AA 4.3%(4/92),correspondingly in healthy controls were GG 52.1%(101/194),AG 43.8%(85/194),AA 4.1%(8/194)respectively,significant differences were found between KD patients and controls(x2=6.47,P=0.039).G allele frequency of BLK(rs2254546)in KD patients(81.5%,150/184)was higher than that in controls(74.0%,287/388,x2=1.553,P=0.047).Conclusions For the children in southern China,FCGR2A SNPs(rs1801274)may be associated with the susceptibility to KD,and the A allele may increase the risk of KD.BLK SNPs(rs2254546)is also found to be associated with the susceptibility to KD,and the G allele may increase the risk of KD.
