DNA methylation and odds ratios for breast cancer risk associated with lack of DNA methylation.

6 genes analyzed showed differences in the methylation pattern between cases and controls when the data was adjusted for age; 5 remained significant even after adjusting for age and family history of breast cancer. ERT = estrogen receptor-α target; DMHR = differently methylated depending on hormone receptor status; PCGT = stem cell polycomb group target; MBC = methylated in breast cancer; * indicates P values <0.05.
