Abstract：
:It is highly possible that copy number variations (CNVs) in susceptible regions have effects on chronic obstructive pulmonary disease (COPD) development, while long noncoding RNA (lncRNAs) have been shown to cause COPD. We hypothesized that the common CNV, named nsv823469 located on 6p22.1, and covering lncRNAs (major histocompatibility complex, class I, A (HLA-A) and HLA complex group 4B (HCG4B)) has an effect on COPD risk. This association was assessed through a two-stage case-control study, and was further confirmed with COPD and pulmonary function-based family analyses, respectively. The copy number loss (0-copy/1-copy) of nsv823469 significantly decreased risk of COPD compared with normal (2-copy) (OR = 0.77, 95% CI = 0.69-0.85). The loss allele, inducing copy number loss of nsv823469, has a tendency to transmit to offspring or siblings (P = 0.010) and is associated with forced expiratory volume in 1 second (FEV1) (P = 0.030). Furthermore, the copy number loss of nsv823469 in normal pulmonary tissue decreases the expression levels of HCG4B (r = 0.315, P = 0.031) and HLA-A (r = 0.296, P = 0.044). Our data demonstrates that nsv823469 plays a role in COPD and pulmonary function inheritance by potentially altering expression of HCG4B.
