Gene loci selected for the case/control study.

Gene loci (either one locus or two separate loci of the same gene) have been analyzed and were selected based on their frequency of methylation in peripheral blood cell DNA in the general population of 83 healthy postmenopausal women. Genes that were selected for further analysis in the case/control study are indicated with an asterisk. ERT = estrogen receptor-α target; DMHR = differently methylated depending on hormone receptor status; PCGT = stem cell polycomb group target; MBC = methylated in breast cancer.
