Abstract
- A new platform for DNA methylome analysis is Illumina's Infinium HumanMethylation450. This technology is an extension of the previous HumanMethylation27 BeadChip and allows the methylation status of 12 samples per chip and 4 to 8 chips (total of 48 to 96 samples) to be assessed simultaneously for more than 480,000 cytosines across the genome. The platform incorporates two different probe types using different assay designs (InfiniumI and InfiniumII). Although this has allowed the assessment of more CpG sites, it has also introduced technical variation between the two probe types, which has complicated the analysis process. Many groups are working on normalization methods and analysis pipelines while many others are struggling to make sense of their new data sets. This motivated the organization of a meeting held at University College London that focused solely on the analysis methods and problems related to this new platform. The meeting was attended by 125 computational and bench scientists from 11 countries. There were 10 speakers, a small poster session and a discussion session.
