Abstract
PURPOSE: Multiple genetic factors are associated with chronic obstructive pulmonary disease (COPD). The association of gene encoding vitamin D binding protein (VDBP, GC) with COPD has been controversial. We sought to investigate the types of GC variants in the Korean population and determine the association of GC variants with COPD and lung function in the Korean population.
MATERIALS AND METHODS:The study cohort consisted of 203 COPD patients and 157 control subjects. GC variants were genotyped by the restriction fragment-length polymorphism method. Repeated measures of lung function data were analyzed using a linear mixed model including sex, age, height, and pack-years of smoking to investigate the association of GC genetic factors and lung function.
RESULTS:GC1F variant was most frequently observed in COPD (46.1%) and controls (42.0%). GC1S variant (29.0% vs. 21.4%; p=0.020) and genotype 1S-1S (8.3% vs. 3.4%; p=0.047) were more commonly detected in control than COPD. According to linear mixed model analysis including controls and COPD, subjects with genotype 1S-1S had 0.427 L higher forced expiratory volume in 1 second (FEV₁) than those with other genotypes (p=0.029). However, interaction between the genotype and smoking pack-year was found to be particularly significant among subjects with genotype 1S-1S; FEV₁ decreased by 0.014 L per smoking pack-year (p=0.001).
CONCLUSION:This study suggested that GC polymorphism might be associated with lung function and risk of COPD in Korean population. GC1S variant and genotype 1S-1S were more frequently observed in control than in COPD. Moreover, GC1S variant was more common in non-decliners than in rapid decliners among COPD.
