Fig. 6

Example of β values distribution for one of the “clean” Infinium probes (with no SNP in the interrogated CpG site and no other confounding effect). Upper panel: Individual β values for the type I probe (cgx* — the probe’s name is not disclosed — validation study in progress; manuscript in preparation). Upper panel: Fluorescence readouts for the probe cgx. In the absence of SNPs, strong red and no green signal indicate unmethylated status, while similar, medium-range intensity of green and red signals indicates a partial methylation status
