Is there a link between DNA and Obesity?
... People with the high risk variant are likely to be attracted to high calorie and sugary foods. This is because the FTO gene works with the DRD2 gene, which alters how the dopamine system in the brain works, to send dopamine signals to boost cravings when people see high calorie or sugary foods.

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
