Fig. 2From: Epigenome data release: a participant-centered approach to privacy protectionExample in which methylation is indirectly affected by a SNP. The CpG site is normally methylated (left) when the genomic sequence at a downstream SNP position is a C. When the downstream SNP is mutated to a T, the CpG site is affected and becomes unmethylated, allowing the conversion of the cytosine residues at the CpG site to uracil (right)Back to article page
