Abstract:
Objective To explore the relationship between the polymorphism of integrin-metalloproteinase-33 (ADAM33) gene and bronchial asthma. Methods Subjects were selected from the Department of Respiratory Medicine in our department from June 2015 to December 2016 in the treatment of 120 cases of asthma patients as the observation group, the same period into our hospital physical examination of 120 healthy children as the control group. The patients were enrolled in the upper extremity elbow vein and extracted DNA, followed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing. The frequency of T2 genotype distribution and the frequency distribution of T2 locus and the relative risk of asthma were compared according to Hardy-Weinberg equilibrium law. Results The frequency of A gene in the T2 allele of the subject was significantly higher than that of the control group. The frequency of A gene in the T2 allele was significantly higher than that in the control group (P<0.05) There was significant difference between the two groups (χ2=8.09, P=0.00), and the increase of A allele was the risk factor of asthma (OR=2.32); the observation group T2 gene AG (χ2=4.21, P=0.04), and the increase of AG allele was the risk factor of asthma. The frequency of asthma was significantly higher than that of control group (OR=1.89). Conclusion ADAM33 gene T2 locus polymorphism is significantly associated with bronchial asthma, which can significantly increase the risk of bronchial asthma.
