Gene polymorphisms and chronic obstructive pulmonary disease.

ABSTRACT: The genetic component was suggested to contribute to the development of chronic obstructive pulmonary disease (COPD), a major and growing public health burden. The present review aims to characterize the evidence that gene polymorphisms contribute to the aetiology of COPD and related traits, and explore the potential relationship between certain gene polymorphisms and COPD susceptibility, severity, lung function, phenotypes, or drug effects, even though limited results from related studies lacked consistency. Most of these studies were association studies, rather than confirmatory studies. More large-sized and strictly controlled studies are needed to prove the relationship between gene polymorphisms and the reviewed traits. More importantly, prospective confirmatory studies beyond initial association studies will be necessary to evaluate true relationships between gene polymorphisms and COPD and help individualized treatment for patients with COPD.

Project description:BackgroundA number of polymorphisms in vitamin D binding protein (VDBP) (GC) gene have been implicated in risk of chronic obstructive pulmonary disease (COPD), but the results were controversial. GC1F, GC1S, and GC2 are three common variants of the VDBP gene [single nucleotide polymorphisms (SNPs): rs7041 and rs4588], which were reported to be associated with COPD. This study aimed to explore the association between VDBP gene polymorphisms and COPD.MethodsPubMed, EMBASE, Web of Science (Medline) and Chinese National Knowledge Infrastructure (CNKI) were searched for eligible case-control studies. Study quality was evaluated using the Newcastle-ottawa quality assessment scale (NOS). After the most appreciated genetic model was identified, a meta-analysis was performed to test the association between VDBP gene polymorphism and COPD. The pooled odds ratios (ORs) were performed respectively for the most appreciated genetic model, single allele comparison and homozygous gene model analysis. Summary receiver operating characteristic curve (SROC) analyses were applied to evaluate the diagnostic performance of polymorphism of VDBP to COPD.ResultsEight studies containing 2,216 participants were included. The analyses of the most appropriate genetic models offered significant results in recessive model of GC1F/1S group (OR =2.18), co-dominant genetic model in GC1F/2 group (1F-1F vs. 2-2: OR =4.87; 1F-2 vs. 2-2: OR =1.73; 1F-1F vs. 1F-2: OR =2.27). In single allele comparison, significant results were obtained in GC1F vs. GC1S and GC1F vs. GC2, with ORs were 1.47 and 1.77, respectively. In homozygous genes comparison, the OR was 2.51 in GC1F homozygote vs. other genotypes. Subgroup analyses offered the same significant results in Asian population, but not in Caucasian population. The SROC analyses showed the less accurate performance of polymorphism of VDBP to COPD.ConclusionsThere is a close association between COPD and GC gene polymorphisms. The GC1F allele could be a risk factor, the GC1S and GC2 allele may be protective factors in Asian, but not in Caucasians.
