Genome-wide DNA methylation profiling of DNA extracted from dried blood spots from preterm and term subjects using longitudinal samples collected at birth and 18 years of age. Infinium HM450 arrays were used to measure methylation at 347,789 autosomal CpGs. DNA was analysed from individuals at birth and 18-years and included 12 preterm and 12 term controls.
Overall design
Bisulphite converted DNA from the 48 samples were hybridised to the Illumina Infinium 450K Human Methylation Beadchip
