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.
This meta-analysis suggested that S1 (rs3918396) polymorphism of ADAM33 is associated with increased risk of COPD in Asian (China) but not in Caucasians.
Two SNPs in TGFB1 (C to T substitution at nucleotide -509 and substitution of leucine 10 with proline (Leu10Pro)), Leu50Val in SFTPA1 and Ala160Thr in SFTPD showed evidence suggestive of association with FEV(1)/IVC in subjects with GOLD stage >or=2 COPD.
