Abstract:
Objective To investigate the polymorphism of glutathione S-transferease P1 gene(GSTP1) and the association between the mutation and susceptibility in childhood asthma.Methods The distribute frequency of Ile105/Ile105,Ile105/Val105 and Val105/Val105 ge-notype in GSTP1 of 51 children with asthmatic and 40 normal children were studied with polymerase chain reaction-restriction tragment length polymorphism(PCR-RFLP).Results The frequencies of Ile/Ile Ile/Val,Val/Val genotype were 66.7%,27.4% and 5.9%,the frequencies of Ile,Val allele were 80.4% and 19.6% in the asthmatic group.But the frequencies of Ile/Ile,Ile/Val,Val/Val genotype were 90.0%,7.5% and 2.5%,the frequencies of Ile,Val allele were 93.8%,6.2% in control group.The frequencies Ile/Val,Val/Val genotype and Val allele in asthmatic group were more than that in control group.A significant difference was found in the frequency distribution of GSTP1 genotypes between two groups(?2=6.947 P
