Abstract: Patients with obstructive sleep apnoea-hypopnoea syndrome (OSAHS) have elevated circulating levels of tumour necrosis factor (TNF)-alpha. The hypothesis in this study was that OSAHS might be associated with the TNF-alpha (-308A) gene polymorphism, which results in increased TNF-alpha production. This hypothesis was examined in OSAHS patients, their siblings and population controls. A total of 206 subjects were recruited. All underwent sleep studies and clinical review, and were subsequently classified as having OSAHS or not depending on apnoea-hypopnoea frequency, sex, age and symptoms. All subjects had blood collected and genotyping was performed on DNA extracted from peripheral leukocytes. Some 192 random UK blood donors were used as population controls. The results demonstrated a significant association for TNF-alpha (-308A) allele carriage with OSAHS (OR=1.8 95% Confidence interval: 1.18-2.75) when compared with population controls. Siblings with OSAHS were significantly more likely to carry the TNF-alpha (-308A) allele. In addition, 21 pairs of male siblings discordant for carriage of the -308A allele showed a significant level of discordance for the OSAHS phenotype. In conclusion, this study demonstrates an association of tumour necrosis factor-alpha (-308A) carriage with obstructive sleep apnoea-hypopnoea syndrome, suggesting that inflammation may be implicated in the pathogenesis of this condition.

Abstract: Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. In idual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of intervening in pathways underlying lung function. We highlight new putative causal variants, genes, proteins and pathways, including those targeted by existing drugs. These findings bring us closer to understanding the mechanisms underlying lung function and COPD, and should inform functional genomics experiments and potentially future COPD therapies.

Abstract: Background: Over 90 regions of the genome have been associated with lung function to date, many of which have also been implicated in chronic obstructive pulmonary disease. Methods: We carried out meta-analyses of exome array data and three lung function measures: forced expiratory volume in one second (FEV 1 ), forced vital capacity (FVC) and the ratio of FEV 1 to FVC (FEV 1 /FVC). These analyses by the SpiroMeta and CHARGE consortia included 60,749 in iduals of European ancestry from 23 studies, and 7,721 in iduals of African Ancestry from 5 studies in the discovery stage, with follow-up in up to 111,556 independent in iduals. Results: We identified significant (P ·8x10 -7 ) associations with six SNPs: a nonsynonymous variant in RPAP1 , which is predicted to be damaging, three intronic SNPs ( SEC24C, CASC17 and UQCC1 ) and two intergenic SNPs near to LY86 and FGF10. Expression quantitative trait loci analyses found evidence for regulation of gene expression at three signals and implicated several genes, including TYRO3 and PLAU . Conclusions: Further interrogation of these loci could provide greater understanding of the determinants of lung function and pulmonary disease.

Abstract: Estimates from genome-wide association studies (GWAS) of unrelated in iduals capture effects of inherited variation (direct effects), demography (population stratification, assortative mating) and relatives (indirect genetic effects). Family-based GWAS designs can control for demographic and indirect genetic effects, but large-scale family datasets have been lacking. We combined data from 178,086 siblings from 19 cohorts to generate population (between-family) and within-sibship (within-family) GWAS estimates for 25 phenotypes. Within-sibship GWAS estimates were smaller than population estimates for height, educational attainment, age at first birth, number of children, cognitive ability, depressive symptoms and smoking. Some differences were observed in downstream SNP heritability, genetic correlations and Mendelian randomization analyses. For ex le, the within-sibship genetic correlation between educational attainment and body mass index attenuated towards zero. In contrast, analyses of most molecular phenotypes (for ex le, low-density lipoprotein-cholesterol) were generally consistent. We also found within-sibship evidence of polygenic adaptation on taller height. Here, we illustrate the importance of family-based GWAS data for phenotypes influenced by demographic and indirect genetic effects.

Abstract: Newborn heel prick blood spots are routinely used to screen for inborn errors of metabolism and life-limiting inherited disorders. The potential value of secondary data from newborn blood spot archives merits ethical consideration and assessment of feasibility for public benefit. Early life exposures and behaviours set health trajectories in childhood and later life. The newborn blood spot is potentially well placed to create an unbiased and cost-effective population-level retrospective birth cohort study. Scotland has retained newborn blood spots for all children born since 1965, around 3 million in total. However, a moratorium on research access is currently in place, pending public consultation. We conducted a Citizens’ Jury as a first step to explore whether research use of newborn blood spots was in the public interest. We also assessed the feasibility and value of extracting research data from dried blood spots for predictive medicine. Jurors delivered an agreed verdict that conditional research access to the newborn blood spots was in the public interest. The Chief Medical Officer for Scotland authorised restricted lifting of the current research moratorium to allow a feasibility study. Newborn blood spots from consented Generation Scotland volunteers were retrieved and their potential for both epidemiological and biological research demonstrated. Through the Citizens’ Jury, we have begun to identify under what conditions, if any, should researchers in Scotland be granted access to the archive. Through the feasibility study, we have demonstrated the potential value of research access for health data science and predictive medicine.
