From: DNA methylation changes that precede onset of dysplasia in advanced sessile serrated adenomas
Array methylation differences between SSAD backgrounds and SSAs. Globally SSAD backgrounds are more methylated than SSAs in island regions, but the proportion of hypermethylated probes decreases towards shore, shelf and open sea regions. The same trend is accentuated when only promoter probes are analysed. SSAD, sessile serrated adenoma with dysplasia; SSA, sessile serrated adenoma.
