In addition, the A alleles in CHRNA3 rs1051730 and CHRNA5 rs16969968 were associated with the risk for LC (OR = 1.66, P = 0.07 and OR = 1.57, P = 0.1, respectively) and for COPD (OR = 2.04, P = 0.01 and OR = 1.91, P = 0.02, respectively).
The FPRP test results were as follows: 1) when the prior probability was 0.001 and the OR was 1.5, ADAM33 rs612709, CHRNA3/5 rs1051730, CHRNA3/5 rs8034191, CHRNA3/5 rs16969968, and TGFB1 rs1800470 were truly associated with COPD risk (FPRP < 0.2); 2) when the prior probability was 0.000001 and the OR was 1.5, all the variants except TGFB1 rs1800470 remained noteworthy; and 3) when the probability was 0.000001 and the OR was 1.2, ADAM33 rs612709 and CHRNA3/5 rs1051730 remained true positives.
Significant associations between the 4 SNPs and COPD were identified under allele (rs1051730: OR = 1.14, 95%CI = 1.10-1.18; rs8034191: OR = 1.29, 95%CI = 1.18-1.41; rs6495309: OR = 1.26, 95%CI = 1.09-1.45; rs16969968: OR = 1.27, 95%CI = 1.17-1.39) and genotype models.
Four SNPs (rs1964678, rs12593229, rs965604 and rs13180) in IREB2 were associated with forced expiratory volume in 1 s (FEV(1))% predicted and three SNPs (rs16969968, rs8034191 and rs1051730) in CHRNA3/5 were both associated with FEV(1)% predicted and FEV(1)/FVC in COPD cases (P range 0.007-0.050).
In models adjusting for cigarettes-per-day, we confirm the association between rs16969968 and lung cancer (p<10(-20)) and observe a nominally significant association with COPD (p = 0.01); the other loci are not significantly associated with either lung cancer or COPD after adjusting for rs16969968.
Large-scale association analysis identifies new lung cancer susceptibility loci and heterogeneity in genetic susceptibility across histological subtypes.
Analysis of differential allelic expression (DAE) of three single nucleotide polymorphisms (rs503464, rs55853698 and rs55781567) tagging the expression haplotypes of the CHRNA5 promoter indicated statistically significant DAE at rs55853698 and rs55781567, in both normal lung and lung adenocarcinoma.
