From the 22 October 2012 article at Medical News Today

A University of British Columbia and Centre for Molecular Medicine and Therapeutics (CMMT) study has revealed that childhood poverty, stress as an adult, and demographics such as age, sex and ethnicity, all leave an imprint on a person’s genes. And, that this imprint could play a role in our immune response. …

Known as epigenetics, or the study of changes in gene expression, this research examined a process called DNA methylation where a chemical molecule is added to DNA and acts like a dimmer on a light bulb switch, turning genes on or off or setting them somewhere in between. Research has shown that a person’s life experiences play a role in shaping DNA methylation patterns. ..

“We found biological residue of early life poverty,” said Michael Kobor, an associate professor of medical genetics at UBC, whose CMMT lab at the Child & Family Research Institute (CFRI) led the research. “This was based on clear evidence that environmental influences correlate with epigenetic patterns.” ..
