Association of ADAM33 gene polymorphisms with adult concomitant allergic rhinitis and asthma in Chinese Han population

摘要

Allergic Rhinitis (AR) and allergic asthma (AS) are very common diseases involving genetic and environmental factors. Most patients with asthma also have rhinitis, which suggests the concept of 'one airway, one disease'. A disintegrin and metalloproteinase 33 (ADAM33) was discovered as the first asthma-susceptible gene by positional cloning. To evaluate the potential influences of ADAM33 gene polymorphisms on concomitant allergic rhinitis and asthma (ARA), a case-control study was conducted in Han population of Northeast China. Six polymorphic sites (V4, T + 1, T2, T1, S1 and Q - 1) were genotyped in 135 ARA patients and 151 controls (CTR). Genotypes were determined by the polymerase chain restriction fragment length polymorphism (PCR-RFLP) method. Data was analyzed using the Chisquaretest and Haploview software. The SNPs (V4 G/C, T2 A/G, T1 G/A, and Q - 1A/G) of the ADAM33 gene may be the causal variants in ARA disease.
