GEO Search Methylation Datasets

Search NCBI GEO for DNA methylation array datasets, including Illumina 450K, EPIC (850K), and other methylation profiling platforms. Returns dataset accessions (GSE IDs), titles, summaries, platform information, sample counts, and organisms. DNA methylation arrays measure methylation levels at hundreds of thousands of CpG sites genome-wide. Use this to find published methylation studies for specific conditions, tissues, or diseases. Follow up with GEO_get_dataset_details for full metadata.
