Quantification of global mitochondrial DNA methylation levels and inverse correlation with age at two CpG sites

class="figure-viewer-img"

Figure 1. Mean methylation levels at 54 CpG sites across the mitochondrial genome (category labels denote reference base position). While methylation levels are typically 2‐6%, considerable inter‐individual variation was observed, indicated by minimum and maximum range bars. CpG sites within the 12S RNA gene are highlighted.
