Functional analysis reveals links between DMRs and aging, neurodevelopment, and calcium transport. a Bar diagram shows differential methylation between Hi and Lo in the 100 strongest peaks previously reported as either hyper- or hypomethylated in aged fibroblast cells [34]. b Shows the normalized distribution of disease classes associated with the genes located closest to the p < 0.0001 DMRs (n = 407). Normalization was done to control for publication bias, by dividing the number of DMR genes associated with a disease class with the total number of genes present within that same class. c Heatmap showing the same subset of the DMRs as in b. Columns represent normalized counts of each child and are ordered by hair cortisol rank. Rows represents median centered Z-scores of individual DMRs, where the row order has been determined by hierarchical cluster analysis (euclidean distance; also presented as a dendogram to the right). d Cluster analysis of DMRs associated with genes involved in axon guidance (GO:0007411). Red indicates a significantly robust cluster determined by bootstrap resampling.
