Fig. S1 CpGs typed on Infinium 450K array are irregularly spaced in the genome: Frequency distribution of distance (bp) between neighbouring CpGs on the Infinium 450K array. The inset shows a zoomed-in region of distances less than 5000 bp, where the majority of CpGs reside.

Fig. S2 Correlation of CpG methylation levels of probes within close distances is discernible of the Infinium 450K array: Pearson correlation of pairwise Infinium 450K measured methylation levels (y-axis) with distance (bp) (x-axis). The inset shows a zoomed-in region of distances < 2500 bp, where the correlation ranges from approximately 0.9 to 0.1.

Fig. S3 Correlation of CpG methylation levels with distance for different age groups: a) Pearson correlation of pairwise Infinium 450K measured methylation levels (y-axis) with distance (bp) (x-axis). b) The figure shows a zoomed-in region of distance < 250 bp.

Fig. S4 Relationship between number of significant DMRs identified and a) sample size or b) age difference in sample set.

Fig. S5 Relationship between number of significant VMRs identified and a) sample size or b) median subject age in sample set.

Fig. S6 Heat map of CpG island enrichment results. Genomic regions of varying proximity to CpG islands are indicated on the x-axis and region lists on the y-axis. Cells are coloured for P-value of enrichment.
