Non-genetic markers may be better predictors for breast cancer development than DNA mutations
Non-genetic markers for hereditary breast cancer identified

DNA methylation may be a better predictor for the risk of developing breast cancer than DNA mutations of known breast cancer genes, a new study found. DNA methylation is a form of epigenetic regulation of gene expression, without changing the DNA itself. Epigenetics might thus mimic genetic variation, predisposing an individual to breast cancer and possibly other heritable diseases.
