DNA methylation profiling of 154 triple negative breast cancers using the Illumina EPIC 850K platform

Genome-wide DNA methylation profiles for 154 triple negative breast cancer (TNBC) samples from the Swedsh Cancerome Analysis Network - Breast (SCAN-B) cohort. Genomic DNA from 154 triple negative breast cancer (TNBC) samples was treated with bisulfite and hybridized to Illumina EPIC 850K arrays using standard protocols. Raw iDat files were processed using the "minfi"-package in R as well as custom R-scripts to produce normalized beta values. Both raw intensity values from minfi and the final normalized data are included for each sample.
