2 Heterozygosity for E292V in ABCA3, lung function and COPD in 64,000 individuals Respiratory Research 2012, 13:67 doi:10.1186/1465-9921-13-67 Marie Bækvad-Hansen (baekvad@gmail.com}) Børge G Nordestgaard (brno@heh.regionh.dk}) Morten Dahl (dahlos2003@yahoo.dk}) ISSN 1465-9921 Article type Research Submission date 23 March 2012 Acceptance date 27 July 2012 Publication date 6 August 2012 Article URL http://respiratory-research.com/content/13/1/67 This peer-reviewed article was published immediately upon acceptance.

10 Methods We screened 760 individuals with extreme pulmonary phenotypes and identified three novel (H86Y, A320T, A1086D) and four previously described mutations (E292V, P766S, S1262G, R1474W) in the ABCA3 gene. Login to comment
77 H86Y, A320T and A1086D were novel variants, whereas E292V, P766S, S1262G and R1474W have been described previously. Login to comment
78 Two individuals heterozygous for P766S and one individual heterozygous for R1474W suffered from interstitial lung disease (Additional file 4). Login to comment
88 The observed reductions in pulmonary function were almost similar in absolute numbers to those observed for surfactant protein-B 121ins2, a mutation which in the homozygous state associates with a phenotype somewhat similar to that for E292V compound heterozygosity. Login to comment
96 Individuals heterozygous for H86Y, A320T, P766S, S1262G, or R1474W did not differ from wildtypes in FEV1%predicted, FVC%predicted or FEV1/FVC (p≥0.19). Login to comment
98 This individual was compound heterozygous for P766S and S1262G and was not identified among the extreme phenotypes group. Login to comment
103 For the H86Y, P766S and R1474W mutations, risk of COPD did not deviate significantly from 1.0. Login to comment

135 Numbers of individuals with surfactant protein-B 121ins2 heterozygosity and α1-antitrypsin ZZ homozygosity differ slightly from the number of individuals with an ABCA3 E292V genotype due to different number of study subjects available for analysis within the study period Discussion To test whether individuals heterozygous for ABCA3 variants have reduced lung function and increased risk of COPD in the general population, we screened 760 individuals with extreme lung phenotypes for genetic variations in the ABCA3 gene and identified three novel (H86Y, A320T, A1086D) and four previously described variations (E292V, P766S, S1262G, R1474W).
