Fig. 2. Representative regions of differential methylation in human anxiety.
A smoothing plot that shows the relative location of differentially methylated (y axis) CpG dinucleotides (x axis; black tick marks) in GNAS (a), NAV1 (b), IGF2 (c), and CRTC1 (d). The DNA methylation profiles for the anxious (red) and unaffected (control; blue) twin-pairs are shown and the genomic region of significance between twin-pairs is highlighted (peach). Each corresponding co-twin is indicated by a different line pattern (pair A = solid; B = dashed; C = dash + dot)
