B2097 - Analysis of correlation patterns in DNA methylation through the lifecourse - 23/10/2013
Outline
DNA methylation data has recently been generated from ALSPAC samples at multiple timepoints using the Illumina HM450k DNA methylation array. Genome-wide correlation analysis is now possible to (a) identify potential coregulation and (b) to inform dimension reduction strategies to data analysis. It is also possible to explore the correlation between timepoints to determine which CpG sites in the genome are functionally stable, and which change over time.
Aims
1. Windowed analysis across the genome to generate "methylation correlation maps" at all time-points
2. Genome-wide analysis of correlation between variable loci to identify networks of genes that appear to be coregulated
3. Analysis of correlation of methylation between timepoints at each site in the HM450k to identify stable and labile CpGs.
