Epidemiological evidence highlights the role of early life factors on adult FVC, pointing to environmental exposures and genes affecting lung development as risk factors for low FVC later in life. Although highly heritable, a small number of genes have been found associated with FVC, and we aimed at identifying further genetic variants by focusing on lung development genes.</p></sec><sec id="sec002"><title>Methods</title><p>Per-allele effects of 24,728 SNPs in 403 genes involved in lung development were tested in 7,749 adults from three studies (NFBC1966, ECRHS, EGEA). The most significant SNP for the top 25 genes was followed-up in 46,103 adults (CHARGE and SpiroMeta consortia) and 5,062 children (ALSPAC). Associations were considered replicated if the replication p-value survived Bonferroni correction (<italic>p</italic><0.002; 0.05/25), with a nominal p-value considered as suggestive evidence. For SNPs with evidence of replication, effects on the expression levels of nearby genes in lung tissue were tested in 1,111 lung samples (Lung eQTL consortium), with further functional investigation performed using public epigenomic profiling data (ENCODE).</p></sec><sec id="sec003"><title>Results</title><p><italic>NCOR2</italic>-rs12708369 showed strong replication in children (p = 0.0002), with replication unavailable in adults due to low imputation quality. This intronic variant is in a strong transcriptional enhancer element in lung fibroblasts, but its eQTL effects could not be tested due to low imputation quality in the eQTL dataset. <italic>SERPINE2</italic>-rs6754561 replicated at nominal level in both adults (p = 0.036) and children (p = 0.045), while <italic>WNT16-</italic>rs2707469 replicated at nominal level only in adults (p = 0.026). The eQTL analyses showed association of <italic>WNT16-</italic>rs2707469 with expression levels of the nearby gene <italic>CPED1</italic>. We found no statistically significant eQTL effects for <italic>SERPINE2</italic>-rs6754561.</p></sec><sec id="sec004"><title>Conclusions</title><p>We have identified a new gene, <italic>NCOR2</italic>, in the retinoic acid signalling pathway pointing to a role of vitamin A metabolism in the regulation of FVC. Our findings also support <italic>SERPINE2</italic>, a COPD gene with weak previous evidence of association with FVC, and suggest <italic>WNT16</italic> as a further promising candidate.</p></sec></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Burney, Pg" uniqKey="Burney P">PG Burney</name></author><author><name

Unlike the ratio of forced expiratory volume in 1 second (FEV<sub>1</sub>) to FVC, an indicator of airway obstruction, FVC is a strong predictor of all-cause mortality in asymptomatic adults without chronic respiratory conditions[<xref rid="pone.0147388.ref001" ref-type="bibr">1</xref>]. Although the origins of a low FVC in the general population are poorly understood, there is a strong link to poverty[<xref rid="pone.0147388.ref002" ref-type="bibr">2</xref>], and in particular to low socio-economic status in early life[<xref rid="pone.0147388.ref003" ref-type="bibr">3</xref>]. Endemic vitamin A deficiency is associated with low FVC, and maternal supplementation with vitamin A before, during and after pregnancy, improves FVC in offspring[<xref rid="pone.0147388.ref004" ref-type="bibr">4</xref>]. Low FVC has also been associated with early exposure to particulate air pollution[<xref rid="pone.0147388.ref005" ref-type="bibr">5</xref>]. The deviation of an individual’s FVC values (and lung function in general) from the population mean has been shown to remain stable over time, with future values being predicted by early measurements (“tracking”)[<xref rid="pone.0147388.ref006" ref-type="bibr">6</xref>], which means that early life and genetic effects that manifest in childhood will influence the individual’s whole FVC life trajectory. Taken together, this evidence highlights the role of early life factors on adult FVC, which points to environmental exposures and genes affecting the development of the lung. Severe defects in lung development lead to neonatal death, but milder structural or functional defects could affect lung function and increase susceptibility to lung diseases that become clinically detectable during childhood or later life, including asthma and COPD[<xref rid="pone.0147388.ref007" ref-type="bibr">7</xref>]. This is supported by experimental work on <italic>in-vitro</italic> and animal models of lung function and disease[<xref rid="pone.0147388.ref008" ref-type="bibr">8</xref>].</p><p>Knowledge of the genetics of FVC is still limited. Biological candidates for FVC, mainly related to host defense, inflammatory pathway, pulmonary surfactant and oxidative stress, have been evaluated in candidate-gene association studies, but replication has been difficult. New candidates for FVC have been provided by genome-wide association (GWA) studies, the largest being a recent meta-analysis from the joint CHARGE and SpiroMeta consortia on 52,253 individuals, with replication of the top associations in 24,840 individuals[<xref rid="pone.0147388.ref009" ref-type="bibr">9</xref>]. It identified eight loci, of which six new (<italic>EFEMP1</italic>, <italic>BMP6</italic>, <italic>MIR129-2-HSD17B12</italic>, <italic>PRDM11</italic>, <italic>WWOX</italic>, <italic>KCNJ2</italic>), and two previously associated with FEV<sub>1</sub> and FEV<sub>1</sub>/FVC (<italic>GSTCD</italic> and <italic>PTCH1</italic>). The eight loci explain 1.8% of FVC variation, and yet FVC heritability (proportion of FVC variation attributable to genetic factors) is estimated around 40–60% by familial aggregation and twin studies[<xref rid="pone.0147388.ref010" ref-type="bibr">10</xref>, <xref rid="pone.0147388.ref011" ref-type="bibr">11</xref>] and, more recently, genome-wide data[<xref rid="pone.0147388.ref012" ref-type="bibr">12</xref>].</p><p>Available GWA datasets represent an invaluable resource to test hypotheses about the role of genetic pathways involved in specific pathophysiological mechanisms. We hypothesised that focusing on genes lying in pathways related to lung development could help identify new candidates for FVC and further our understanding of the underlying biological mechanisms.</p></sec><sec sec-type="materials|methods" id="sec006"><title>Materials and Methods</title><p>We evaluated the effect on FVC of 403 genes (24,728 SNPs) related to lung development in two stages. In Stage 1, all SNPs were tested for association with FVC in a meta-analysis of three European adult studies (ECRHS[<xref rid="pone.0147388.ref013" ref-type="bibr">13</xref>], NFBC1966[<xref rid="pone.0147388.ref014" ref-type="bibr">14</xref>], EGEA[<xref rid="pone.0147388.ref015" ref-type="bibr">15</xref>]). For replication in adults (CHARGE and SpiroMeta consortia)[<xref rid="pone.0147388.ref009" ref-type="bibr">9</xref>] and children (ALSPAC[<xref rid="pone.0147388.ref016" ref-type="bibr">16</xref>]) in Stage 2, we selected the best signal for the top 25 genes, defined as the SNP with the lowest meta-analysis p-value which satisfied the following criteria: minor allele frequency >0.05 and imputation quality (imputation R<sup>2</sup>) >0.7 in all three studies; low between-study heterogeneity defined as I<sup>2</sup><30%, with I<sup>2</sup> representing the percentage of total variation in effect estimates across studies due to heterogeneity rather than chance.</p><p>The rationale for limiting our replication analysis to the best signal for the top 25 genes was to maximise the probability of successful replication in children, where the sample size was only 5,062. With this sample size, testing for replication of 25 SNPs gives a power of about 80% to detect a variant explaining 0.3% of FVC residual variance, at a Bonferroni corrected p-value threshold of 0.002 (0.05/25). This assuming that genetic effects in children may be slightly stronger than in adults, where the variance explained by the eight loci previously identified[<xref rid="pone.0147388.ref009" ref-type="bibr">9</xref>] was 1.8%, an average of 0.23% per SNP.</p><sec id="sec007"><title>Selection of candidate genes and SNPs</title><p>Two experts in lung development, a basic scientist (C.H.D.) and a clinician scientist (M.H.), compiled a list of genes involved in lung development, first independently and then through agreement. The selection of genes was based on their knowledge of the topic, mainly using genetic evidence from animal models[<xref rid="pone.0147388.ref008" ref-type="bibr">8</xref>, <xref rid="pone.0147388.ref017" ref-type="bibr">17</xref>, <xref rid="pone.0147388.ref018" ref-type="bibr">18</xref>]. This initial list was extended to include additional genes suggested by: 1) pathways information obtained from KEGG[<xref rid="pone.0147388.ref019" ref-type="bibr">19</xref>]–relevant genes lying in the same pathways as those in the initial list; 2) information from published literature identified using HuGE Navigator[<xref rid="pone.0147388.ref020" ref-type="bibr">20</xref>]–genes considered as associated with lung development in previous genetic association studies.

12.0 to 41.8) and a p-value well below Bonferroni correction (<italic>p</italic> = 0.0002). The estimate was very similar to that of Stage 1 (26.1; 7.5 to 44.7), suggesting a relatively stronger effect in children given their lower FVC, although the confidence intervals are wide and conclusions as to a difference in effect sizes cannot be deduced. In line with this, the proportion of FVC residual variance explained by this SNP was much higher in children than in adults from Stage 1, 0.65% vs. 0.11%. Replication of <italic>NCOR2</italic>-rs12708369 could not be performed in adults because of low imputation quality (imputation R<sup>2</sup> = 0.4) and no proxy available. Using publicly available epigenomic profiling data (ChIP-seq) from ENCODE[<xref rid="pone.0147388.ref026" ref-type="bibr">26</xref>] via the UCSC Genome Browser (<ext-link ext-link-type="uri" xlink:href="http://genome.cse.ucsc.edu/">http://genome.cse.ucsc.edu</ext-link>), we found that the intronic variant <italic>NCOR2</italic>-rs12708369 is in a region with regulatory function in lung tissue. The SNP is located within a DNase I hypersensitivity site, in a strong enhancer element with histone mark H3K27ac indicating active chromatin in lung fibroblasts.

The proportion of FVC residual variance explained was only 0.01% in adults from the CHARGE and SpiroMeta consortia (0.10% in Stage 1). This variant is in a conserved region and is located in a DNase I hypersensitivity site in lung fibroblasts. <italic>WNT16</italic>-rs2707469 was not associated with <italic>WNT16</italic> expression but showed suggestive evidence of an effect on a nearby gene, <italic>CPED1</italic>, with the FVC-lowering allele G associated with higher <italic>CPED1</italic> mRNA expression levels (<italic>p</italic> = 0.087; I<sup>2</sup> = 0%; <xref ref-type="supplementary-material" rid="pone.0147388.s002">S2 Fig</xref>).

Our study also provides support for <italic>SERPINE2</italic>, a gene which has previously shown weak evidence of association with FVC, and suggests <italic>WNT16</italic> as a promising candidate requiring further investigation.</p><p><italic>NCOR2</italic> (nuclear receptor corepressor 2), also known as <italic>SMRT</italic> (silencing mediator of retinoid and thyroid hormone), is a potent regulator of retinoid and thyroid hormone signalling. Nuclear receptors are ligand-activated transcription factors that regulate many developmental and physiological processes. Retinoic acid is the biologically active metabolite of vitamin A (retinol) which has a well described role in organogenesis and epithelial homeostasis directing growth, patterning and differentiation of many organs including the lung[<xref rid="pone.0147388.ref027" ref-type="bibr">27</xref>]. <italic>NCOR2</italic> is a transcriptional “platform” protein that acts as a repressive co-regulatory factor for multiple transcription factor pathways. Publicly available data retrieved from BioGPS[<xref rid="pone.0147388.ref021" ref-type="bibr">21</xref>] (Human U133A/GNF1H Gene Atlas database) show that the expression of <italic>NCOR2</italic> in the adult lung is very high and that the gene is also expressed in foetal lung. In this study we found an association of <italic>NCOR2</italic> (rs12708369) with FVC in adults, which strongly replicated in children. Replication in adults from the CHARGE and SpiroMeta consortia could not be performed due to low imputation quality and no data on proxies available either. The <italic>NCOR2-</italic>rs12708369 intronic variant is in a strong transcriptional enhancer element in lung fibroblasts and may therefore affect gene expression levels[<xref rid="pone.0147388.ref028" ref-type="bibr">28</xref>], although we were not able to test this due to the same problem of low imputation quality in the Lung eQTL dataset. The replication of <italic>NCOR2</italic> in children and the known central developmental roles of retinoic acid and thyroid hormone signalling during alveologenesis[<xref rid="pone.0147388.ref029" ref-type="bibr">29</xref>] suggest that this gene may influence lung growth and ultimately FVC. Although retinoic acid has also been postulated to have a role in ongoing alveolar maintenance and regeneration[<xref rid="pone.0147388.ref030" ref-type="bibr">30</xref>], in our study the <italic>NCOR2-</italic>rs12708369 effect in adults could be estimated only in Stage 1 mostly based on 31-year olds, so potential effects on FVC decline would not have been detected. Interestingly, another related gene, the <italic>RARB</italic> encoding the retinoic acid receptor beta, was selected in Stage 1, although it could not be replicated possibly due to the low minor allele frequency of its selected SNP (rs11926758; MAF = 0.06). This gene has been previously associated with measures of airway obstruction in adults and children (FEV<sub>1</sub>/FVC)[<xref rid="pone.0147388.ref031" ref-type="bibr">31</xref>, <xref rid="pone.0147388.ref032" ref-type="bibr">32</xref>], and in infants (V’maxFRC)[<xref rid="pone.0147388.ref033" ref-type="bibr">33</xref>]. Overall our findings point to a role of vitamin A/thyroid metabolism in the regulation of FVC, and suggest the importance of further research investigating genes in related pathways as well as gene-environment interactions with vitamin A intake.</p><p><italic>SERPINE2</italic> is a member of a gene family encoding serpins, highly conserved proteins that help maintain tissue integrity by controlling the activity of proteases in diverse biological processes, in particular by inhibiting serine proteases such as trypsin. <italic>SERPINE2</italic> has a known link to airway obstruction, with strong evidence of association with COPD[<xref rid="pone.0147388.ref034" ref-type="bibr">34</xref>] and some evidence of association with childhood asthma[<xref rid="pone.0147388.ref035" ref-type="bibr">35</xref>]. Our findings support an association with a marker of lung restriction too, FVC, in both adults and children, in line with previous findings of an association with FVC in children that could not be replicated[<xref rid="pone.0147388.ref036" ref-type="bibr">36</xref>]. <italic>SERPINE2-</italic>rs6754561 showed no effect on the expression of <italic>SERPINE2</italic> or nearby genes in the lung. However, although the Lung eQTL dataset represents the largest eQTL mapping study of human lung samples currently available, weak to moderate effects on gene expression may not have been detected due to insufficient statistical power. Cellular heterogeneity in lung tissue may also impair the detection of cell type-specific eQTL[<xref rid="pone.0147388.ref037" ref-type="bibr">37</xref>].</p><p>We also found suggestive evidence of an association of <italic>WNT16</italic> with FVC in adults. <italic>WNT16</italic> belongs to a family of genes encoding 19 Wnt ligands, secreted signalling proteins involved in many developmental processes. Although Wnts are critical for normal lung development[<xref rid="pone.0147388.ref018" ref-type="bibr">18</xref>, <xref rid="pone.0147388.ref038" ref-type="bibr">38</xref>], Wnt16 has not been previously studied in relation to lung function and disease. In addition to lung development, evidence from mouse models suggests that Wnt16 plays a role in tissue repair[<xref rid="pone.0147388.ref039" ref-type="bibr">39</xref>] and in the response to cellular damage[<xref rid="pone.0147388.ref040" ref-type="bibr">40</xref>]. The <italic>WNT16</italic>-rs2707469 intronic variant is in a conserved region with regulatory function in lung fibroblasts. This variant showed no eQTL effect on <italic>WNT16</italic> in the lung, but an effect on a nearby gene, <italic>CPED1</italic> (cadherin-like and PC-esterase domain containing 1). CPED1 has both a cadherin-like domain, thought to have a carbohydrate binding function, and a PC-esterase domain, predicted to modify cell surface biomolecules like glycoproteins. It is possible that Wnt16, which is a glycoprotein containing carbohydrates, could bind to, and/or be modified by, CPED1.</p><p>By focusing on genetic pathways related to lung development, which represent highly plausible candidates for low FVC, our study identifies a novel gene and proposes two further promising candidates which had not been identified in the previous GWA meta-analysis[<xref rid="pone.0147388.ref009" ref-type="bibr">9</xref>]. This shows how a comprehensive hypothesis-driven approach can complement hypothesis-free GWA analyses in identifying variants which failed to reach the strict significance level needed to protect against false positives in genome-wide investigations (typically 5x10<sup>-8</sup>). However, we did miss the association of one of the genes we tested, <italic>PTCH1</italic>, a gene which has shown association with FVC in the previous GWA meta-analysis[<xref rid="pone.0147388.ref009" ref-type="bibr">9</xref>] and had been identified before as associated with FEV<sub>1</sub>/FVC[<xref rid="pone.0147388.ref032" ref-type="bibr">32</xref>, <xref rid="pone.0147388.ref041" ref-type="bibr">41</xref>]. The three SNPs previously identified in <italic>PTCH1</italic> had non-significant p-values in our Stage 1 analysis, most likely due to their relatively low minor allele frequency (MAF between 0.08 and 0.10), which made our analysis underpowered to detect them.</p><p>In conclusion, this study identifies <italic>NCOR2</italic> as a new gene for FVC, indicating the importance of further research into the role of vitamin A intake/supplementation and its interactions with related genes in the regulation of FVC. Our findings also suggest other biological pathways as promising candidates for future investigation. We might expect genes involved in lung development to show stronger effects in childhood, and the relatively large replication estimate of the effect of <italic>NCOR2-</italic>rs12708369 in children seems to support this. We speculate that future investigation of genes involved in lung development in larger samples of children and young adults could identify further genetic variants associated with FVC through their effect on lung growth and maximum level attained.</p></sec><sec sec-type="supplementary-material" id="sec017"><title>Supporting Information</title><supplementary-material content-type="local-data" id="pone.0147388.s001"><label>S1 Fig</label><caption><title>Regional association plots for <italic>NCOR2</italic> rs12708369, <italic>SERPINE2</italic> rs6754561 and <italic>WNT16</italic> rs2707469.</title><p>(DOC)</p></caption><media xlink:href="pone.0147388.s001.doc"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material><supplementary-material content-type="local-data" id="pone.0147388.s002"><label>S2 Fig</label><caption><title>Forest plots for the meta-analyses of lung gene expression levels of <italic>CPED1</italic> associated with <italic>WNT16</italic> variants.</title><p>(DOC)</p></caption><media xlink:href="pone.0147388.s002.doc"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material><supplementary-material content-type="local-data" id="pone.0147388.s003"><label>S1 Table</label><caption><title>Stage 1 study-specific and meta-analysis results for all the 24,728 SNPs in the 403 genes.</title><p>(XLSX)</p></caption><media xlink:href="pone.0147388.s003.xlsx"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material><supplementary-material content-type="local-data" id="pone.0147388.s004"><label>S2 Table</label><caption><title>Spirometry methods for studies in Stage 1.</title><p>(DOC)</p></caption><media xlink:href="pone.0147388.s004.doc"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material><supplementary-material content-type="local-data" id="pone.0147388.s005"><label>S3 Table</label><caption><title>Genotyping and imputation methods for studies in Stage 1.</title><p>(DOC)</p></caption><media xlink:href="pone.0147388.s005.doc"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material></sec></body><back><ack><p><bold>NFBC1966 study</bold>: NFBC1966 received financial support from the Academy of Finland (project grants 104781, 120315, 129269, 1114194, 24300796, Center of Excellence in Complex Disease Genetics and SALVE), University Hospital Oulu, Biocenter, University of Oulu, Finland (75617), NHLBI grant 5R01HL087679-02 through the STAMPEED program (1RL1MH083268-01), NIH/NIMH (5R01MH63706:02), ENGAGE project and grant agreement HEALTH-F4-2007-201413, EU FP7 EurHEALTHAgeing -277849, the Medical Research Council, UK (G0500539, G0600705, G1002319, PrevMetSyn/SALVE) and the MRC, Centenary Early Career Award.
