SNPwatch: We Care a Lot

December 12, 2011
The hormone oxytocin has garnered many names in the media, from the “cuddle chemical” to the “morality molecule,” and it’s clear that it impacts social bonding. A new study suggests that people with at least one A at – a SNP in the oxytocin receptor gene called OXTR – are readily perceived by others as being less empathetic than GG individuals.

SNPwatch: Eating Veggies Can Decrease Genetic Risk for Heart Attack

November 22, 2011
For some, eating a doughnut every morning is a recipe for heart attack. Certain genetic factors are also associated with developing cardiovascular disease. But lifestyle choices can impact the effect of genetics on risk. A new study suggests that eating a prudent diet -- high in raw fruits and vegetables -- can counteract the effect of one of the most well-established genetic risk factors for coronary heart disease.

SNPWatch: Taking Stock of Dengue Shock

November 11, 2011
We all know that mosquitoes can be annoying. In many parts of the world, however, mosquitoes are more than just annoying--they are killers. Dengue fever is a mosquito-borne disease with significant public health impact in tropical regions of the world. Some people infected with the dengue virus suffer life-threatening complications, while others have only mild or no symptoms at all. A new study investigates genetic factors underlying response to dengue infection.

SNPWatch: Genetic Variation Influences How We Respond to Reinforcement

September 20, 2011
Genetics can influence everything from how we respond to different drugs to what techniques help us learn. One genetic variant in particular, located in a gene involved in detecting opioid chemicals like morphine, was previously linked to alcohol and heroin addiction as well as how we react to social rejection. Now a new study finds a connection between this same variant and how humans respond to positive reinforcement.
