Association of ADAM33 gene polymorphisms with asthma in Mongolian and Han groups in Inner Mongolia.

ABSTRACT: Polymorphisms in the gene encoding for A disintegrin and metalloprotease 33 (ADAM33) are closely associated with the risk of bronchial asthma attacks in different populations. We collected blood samples from 248 asthma patients - 130 of the Han ethnic group and 118 of the Mongolian ethnic group - living in the Inner Mongolia region of China, and analyzed the single nuclear polymorphisms (SNPs) of the T1, T2 and V4 loci of the ADAM33 gene using PCR-RFLP (restriction fragment length polymorphism). In addition, we also tested 256 healthy controls (134 and 122 from the Han and Mongolian ethnic groups respectively) for the same SNPs. Three genotypes of the T1, T2 and V4 loci were predominantly detected: while polymorphisms in the T1 locus were significantly associated with asthma risk in both Mongolian and Han ethnicities (P??0.05). In contrast, polymorphisms in the T2 locus showed no significant association with asthma risk in either ethnic group (P?>?0.05, ?P?>?0.05).

Project description:BACKGROUND:Asthma is a common complex chronic, inflammatory polygenic disease with heterogeneous manifestations, affecting individuals of all age groups and posing an immense burden on healthcare resources. A number of studies have identified the association between a disintegrin and metalloprotease 33 (ADAM33) polymorphisms and asthma risk, however, the results still remain inconclusive. The objective of the present study was to identify the effect of ADAM33 variants in asthma susceptibility. METHODS:Eligible case-control studies published between January 2000 and June 2018 was searched and retrieved from online electronic databases. The odds ratio (OR) with its 95% confidence interval (CI) was employed to calculate the effect. RESULTS:A total of 63 case-control studies were finally screened out, including 13,280 asthma patients and 13,340 controls. Eleven SNPs of ADAM33 gene were identified. Our results detected a significant association between ADAM33 T2, Q1, F?+?1 and AA genotype of T?+?1 polymorphisms and asthma risk in total population. Subgroup analysis by ethnicities showed that the alleles and genotypes of T2, Q1 and F?+?1 polymorphisms were associated with asthma susceptibility among Asian populations, while V4 polymorphism was associated with asthma among Caucasian populations. Subgroup analysis by ages showed that T2, F?+?1 and ST?+?4 polymorphisms were associated with childhood asthma, while Q1 and V4 polymorphisms were associated with asthma risk in adults. Subgroup analysis by asthma severity showed that only the G allele of ADAM33 T1 polymorphism was associated with the severity of asthma when compared with the controls. In addition, T2, Q1 and F?+?1 polymorphisms of ADAM33 were significantly associated with increased the asthma risk in Chinese asthma patients. CONCLUSIONS:Our results found that T2, Q1 and F?+?1 polymorphisms of ADAM33 gene might contribute to asthma risk. Future well-designed case-control studies with large population and more ethnicities are still needed to estimate the association.
