Little is known about whether DNA methylation (DNAm) of cytosine-phosphate-guanine (CpG) sites at birth predicts patterns of lung function development. We used heel prick DNAm from the F1-generation of Isle of Wight birth cohort (IOWBC-F1) for discovery of CpGs associated with lung function trajectories (Forced Expiratory Volume, Forced Vital Capacity, their ratio, and Forced Expiratory Flow at 25-75%) over the first 26 years, stratified by sex. We replicated the findings in the Avon Longitudinal Study of Parents and Children (ALSPAC) using cord blood DNAm.
Epigenome-wide screening was applied to identify CpGs associated with lung function trajectories in 396 boys, and 390 girls of IOWBC-F1. Replication in ALSPAC focused on lung function at ages 8, 15 and 24 years. Statistically significantly replicated CpGs were investigated for consistency in direction of association between cohorts, stability of DNAm over time in IOWBC-F1, relevant biological processes, and for association with gene expression (n=161) in IOWBC F2-generation (IOWBC-F2).
Differential DNAm of 8 CpGs on genes GLUL, MYCN, HLX, LHX1, COBL, COL18A1,
STRA6, and WNT11 involved in developmental processes, were significantly associated with lung function in the same direction in IOWBC-F1 and ALSPAC, and showed stable patterns at birth, age 10 and 18 years between high and low lung function trajectories in IOWBC-F1. CpGs on LHX1 and COL18A1 were linked to gene expression in IOWBCF2.
In two large cohorts, novel DNAm at birth were associated with patterns of lung function in adolescence and early adulthood providing possible targets for preventative interventions against adverse pulmonary function development.
