The G allele of GSTP1 showed important Epigenetic Reader Domain adverse association with FEV1 beneath additive and recessive models and with FEV1/FVC beneath recessive model. The association of rs1695 below recessive model with FEV1 remained considerable even soon after correction for numerous testing. The G allele of MMP12 showed considerable good association with FEV1 beneath dominant model and with FEV1/FVC beneath additive and dominant models. Two SNPs in IREB2 showed marginal constructive association with only FEV1 beneath recessive model. The T allele 17493865 of TGF-b showed association with FEV1/FVC under dominant model. 3 SNPs in SERPINE2, showed substantial positive association with each the phenotypes beneath recessive model. The p values remained significant just after correction for many testing only for FEV1. Using a sliding window approach we generated haplotypes of two, three and four SNPs and analyzed their association with COPD, FEV1 and FEV1/FVC. The haplotypes showing nominal important association are presented in table S3. Haplotypes carrying the G allele of rs2276109 had a substantial protective impact against establishing COPD.
