From: Adam33 polymorphisms are associated with COPD and lung function in long-term tobacco smokers
Minor allele frequency of SNPs in ADAM33 that were statistically significantly* different between COPD† cases and controls. *p value < 0.05. SNPs S2 and V4 were not significant after banferroni correction. †COPD: Chronic Obstructive Pulmonary Disease; defined by defined by an FEV1/FVC ratio < 70% and ppFEV1 < 75% (n = 287). Control group were smokers with an FEV1/FVC ratio ≥ 70% and ppFEV1 ≥ 80% (n = 311).
