ABSTRACT
@#ObjectiveTo explore the relationship between ORMDL3 gene polymorphism and Asthma in children.Methods178 cases of children with asthma were divided into mild group and severe group, and 129 cases of children were treated as normal control group who tested blood samples in the PLA General Hospital and its Affiliated Hospital in the recent 4 years. ORMDL3 gene locus rs7216389 genotype was detected, including PCR, restriction endonuclease analysis and bio-statistical aspects of analysis.ResultsThere was significant difference (P<0-05) in 3 genotypes (CC＼TC＼TT). There was no significant difference in TT between the mild group and the control group (P>0-05). The rate of severe group was higher than that in the mild and the control groups(P<0-05). Asthmas in children showed higher T allele frequency.ConclusionORMDL3 gene polymorphism showed a certain relevance with asthma in children.
