DNA Methylation
A brief overview of

A brief overview of DNA Methylation

  • The human genome contains ~32 million CpGs. VERY different between different species
  • CpGs are not evenly spaced across the genome. Tend to be present in clusters, CpG islands
  • CpG methylation can regulate gene expression.

DNA Methylation - Why its important?

DNA Methylation Analysis - Sequencing vs Arrays

What are methylation arrays and how do they work?

Methylation arrays are based on SNP array technology


  • The Infinium Methylation Assay uses two different bead types to detect CpG methylation.
    • The U bead type matches the unmethylated CpG site;
    • the M bead type matches the methylated site.



In the top figure, the unmethylated CpG target site matches with the U probe, enabling single-base extension and detection. It has a single-base mismatch to the M probe, which inhibits extension. If the CpG locus of interest is methylated (bottom figure), the reverse occurs.

  • Coverage: Expanded regulatory regions, non-coding RNAs, intergenic regions
  • Focus: Enhancers, gene bodies, regulatory elements
  • Applications: Tissue-specific studies, regulatory region methylation

Measurement of Methylation Status





  • In the Illumina DNA Methylation Array, we measure methylation in a population of cells.
  • Individual cell can be either 0, 0.5 or 1 at one CpG.
  • Across a population, we get a continuous measurement between [0 - 1].

Measurement of Methylation Status

Illumina arrays measure both methylated (C) and unmethylated (T) signal to get proportion of methylation at a CpG.

\[\beta = \frac{Meth}{Meth + Unmeth}\]

Intuitive, easy to interpret, great for visualization

\[M = log_2 \frac{Meth}{Unmeth}\]

Better statistical properties, recommended for statistical testing

\[ M = log_2 \frac{\beta}{1 - \beta}\]

Can convert between them via a logit transformation.

What happens after you upload your data –

  • methylR will start analyzing your data as you selected,
  • Your data and result will be lost once you close the browser
  • No storage for your data or analysis result.
  • Only you from your opened browser can see your result.
  • Once you open a new browser window, it will open a new session with a new container.

Please remember:

  • Univerity IT department restart the server without any prior notice.
  • We CANNOT recover your data or result.

  • We used GSE207426 dataset to test our methylR pipeline for Illumina HumanMethylation EPIC array (v1).
  • We found the same number of DMCs in the full dataset (123 510 DMCs) as well as in the TSS (both TSS200 and TSS1500) + 5′ UTRs subset (26 626 DMCs).
  • We obtained same number (37) of enriched pathways using REACTOME database.
