Background The associations between the interleukin-4 receptor α chain (IL4RA) I50V and
Q551R polymorphisms and asthma risk remained controversial. Methods We searched the …

Background. Asthma is a complex polygenic disease in which gene‐environment
interactions are important. A number of studies have investigated the polymorphism of IL‐1β …

The IL-4R Q576R polymorphism has been reported to increase susceptibility to asthma, but
the results are controversial. Thus, we performed a meta-analysis to evaluate the …

remained controversial and ambiguous. Therefore, we performed a meta-analysis to assess …

The alpha subunit of interleukin 5 receptor (IL5RA) on chromosome 3p26-p24 is known to
regulate the development and function of eosinophils. In an effort to discover additional …

Published data on the association between interleukin-4 (IL-4) rs2243250 (C-589T)
polymorphism and asthma susceptibility are inconclusive. To derive a more precise …

Background. Previously, lots of studies researched the association of interleukin (IL) 13
gene polymorphisms and the risk of asthma, yielding incongruent outcomes. Objective. To …
