Asthma; Meta-analysis; ORMDL3; Polymorphism; rs7216389

While increasing scientific evidence suggests that the ORMDL3 rs7216389 polymorphism may contribute to a higher susceptibility to asthma, many of the current studies have yielded inconclusive results. This meta-analysis aimed to assess the association between the ORMDL3 rs7216389 polymorphism and the risk of asthma. An extensive literature search for relevant studies was ... more

Asthma; Meta-analysis; Polymorphism; Single nucleotide polymorphism

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 association of the IL-4R Q576R polymorphism and asthma risk in the Chinese Han population. A total of sixteen eligible case-control studies that evaluated the relationship between the IL-4R ... more

ADAM33; COPD; Meta-analysis; Polymorphism

Numerous studies have evaluated the association between polymorphisms of a disintegrin and metalloproteinase 33 (ADAM33) gene and chronic obstructive pulmonary disease (COPD) risk; however, the results remain conflicting. The aim of this study was to investigate whether ADAM33S2 and -T1 polymorphisms are associated with susceptibility to COPD risk in the Chinese population. Publications ... more

Asthma; IL-4; Meta-analysis; Polymorphisms; Promoter

This study aimed to more precisely assess the correlation between interleukin-4 (IL-4) promoter polymorphisms and the susceptibility risk of asthma. We conducted association studies on IL-4 promoter C-33T, C-589T, and G-1098T polymorphisms with asthma using data obtained from MEDLINE up to September 2011. Results showed that the polymorphisms IL-4 C-33T and C-589T were significantly ... more

Colorectal cancer; Meta-analysis; Polymorphism; VEGF

Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen involved in a number of pathologic processes, including angiogenesis, tumor growth and metastasis. Polymorphisms of the VEGF gene have been associated with susceptibility to colorectal cancer (CRC). However, the specific association still remains controversial. We made a meta-analysis of the association ... more

Endometrial cancer; Meta-analysis; p53 gene; Polymorphism; susceptibility

Polymorphisms of the p53 gene have been associated with susceptibility to endometrial cancer. However, whether there is a specific association is still controversial. We investigated a possible association between p53 codon 72 polymorphism and endometrial cancer risk by conducting a meta-analysis. Publications addressing this association were selected from the Pubmed, Embase and CBM ... more

Head and neck cancer; Meta-analysis; Polymorphism; XPD

Several studies have investigated the association between Lys751Gln polymorphism in the xeroderma pigmentosum group D (XPD) gene and risk of head and neck cancer; however, the published results are conflicting. We conducted a meta-analysis that comprised 15 published case-control studies examining the association of head and neck cancer risk with XPD Lys751Gln ... more

Human leukocyte antigen; Meta-analysis; Polymorphism; Psoriasis; Risk

Numerous studies have evaluated the association between human leukocyte antigen (HLA) Cw*0602 polymorphism and psoriasis risk. However, the results have been inconsistent. We made a meta-analysis of the association between HLA-Cw*0602 polymorphism and psoriasis risk. Eighteen studies were retrieved, reporting a total of 3419 psoriasis patients and 3297 healthy controls. The associations ... more

Lung cancer risk; Meta-analysis; p21; Polymorphism; Ser31Arg

The cyclin-dependent kinase inhibitor 1A (also known as p21) is thought to be involved in tumor development by mediating cell cycle arrest through the inhibition of cyclin/CDK activity. To explore the relationship of Ser31Arg polymorphism in the p21 gene with the risk of developing lung cancer, we performed an overall and stratified meta-analysis based on ethnicity, lung ... more

Endothelial nitric oxide synthase; Essential hypertension; Meta-analysis; Polymorphism

We examined the effect of polymorphisms in the endothelial nitric oxide synthase gene on the risk for essential hypertension in a Han Chinese population through a meta-analysis of data from 15 studies. Associations between increased risk for essential hypertension and 4b/a were obtained in a dominant model and allele contrast (aa + ab vs bb: odds ratio (OR)FE = 1.26, ... more
