From: “Gap hunting” to characterize clustered probe signals in Illumina methylation array data
Effect of a G/T SNP at the SBE site of Type I probes on percent methylation, methylated signal, unmethylated signal, and a copy number metric. Percent methylation (beta value), methylated signal, unmethylated signal, and a copy number metric plotted against genotype for Type I probes interrogating a CpG site on the forward strand, when the G is the reference genotype. Information was collected across 2 probes. There is an inverse association between dosage of the T allele and signal produced, as predicted in Fig. 3
