There are published evidences of differential methylation pattern in a specific gene hosting locus I'm interested in, between different grade tumors. These data were obtained using the HumMeth450 BeadChip from Illumina. I would like to test the CpG methylation status in some of my samples and it would be of great interest for me to understand which are the site differentially methylated. I was not able however to find the Illumina' CpG database to recover the CG locus designation. Is there a readily-available public database that I've missed, which will allow me obtain these information ?
