Abstract DNA methylation is a key mechanism of epigenetic regulation that is frequently altered in diseases such as cancer. To confirm the biological or clinical relevance of such changes gene-specific DNA methylation changes need to be validated in multiple samples. We have developed the MethMarker http software to help design robust and cost-efficient DNA methylation assays for six widely used methods. Furthermore MethMarker implements a bioinformatic workflow for transforming disease-specific differentially methylated genomic regions into robust clinical biomarkers. Rationale Aberrant DNA methylation is a common event in many cancers 1 2 . Functionally cancer-specific hypermethylation imposes condensed chromatin structure upon CpG islands that normally exhibit an open and .
