Abstract
In this study, we examined and validated how common variants contribute to susceptibility to chronic obstructive pulmonary disease (COPD) in the Han Chinese population. Here, we genotyped 18 nucleotide polymorphisms and evaluated their association with COPD using chi-square test and genetic model analysis (246 COPD patients and 350 controls), and found three SNPs that might cause a predisposition to COPD. Both rs3025030 and rs3025033 are located on chromosome 6 in VEGF-A. We found one risk allele ‘C’ from rs3025030 and another ‘G’ from rs3025033 using the log-additive model (OR 1.40; 95% CI 1.05–5.96; P = 0.022), (OR 1.38; 95% CI 1.03–1.84; P = 0.03). We also found another risk allele ‘A’ of rs9296092 in gene region ZBTB9-BAK1 by the allele model (OR 2.63; 95% CI 1.27–5.45; P = 0.0078), (adjusted OR 3.53; 95% CI 1.12–11.11; P = 0.031). We found a risk haplotype ‘CG’ associated with the risk of COPD (OR 1.39; 95% CI 1.04–1.86; P=0.028). Our results when compared with previous studies showed significant association between VEGF-A polymorphism and COPD. We also identified rs9296092 as a risk factor for COPD.
