Please see also “Poverty linked to epigenetic changes and mental illness -Impoverished adolescents acquire DNA marks, brain changes and depression over time.” Sara Reardon 24 May 2016 for a clear introduction to epigenetics and genomic instability as a background. Environment and stressors affects how genes express and how cells read and respond to gene expression. A marked gene need not be a “damaged gene”, however processes due to environment may alter the expression of a gene. The consequences of this may be many. One outcome may be disease. A marked, undamaged, gene may be transmissible to offspring if it is a germ cell (sperm, egg).
