Keep Smiling | Gene Responsible For Happiness Has Been Located
Happiness and well-being are the topics of an increasing number of scientific studies in a variety of academic disciplines. Policy makers are increasingly focusing on well-being, drawing primarily on the growing body of evidence suggesting that well-being is a factor in mental and physical health. Prior researches have shown that individual differences in happiness and well-being can be partially ascribed to genetic differences between people.
However for the first time in history, researchers have isolated the parts of the human genome that could explain the differences in how humans experience happiness.
Researchers have found three genetic variants for happiness, two variants that can account for differences in symptoms of depression, and eleven locations on the human genome that could account for varying degrees of neuroticism. The genetic variants for happiness are mainly expressed in the central nervous system and the adrenal glands and pancreatic system. The results were published in the journal Nature Genetics.
VU Amsterdam professor Meike Bartels explains: “This study is both a milestone and a new beginning: A milestone because we are now certain that there is a genetic aspect to happiness and a new beginning because the three
variants that we know are involved account for only a small fraction of the differences between human beings. We expect that many variants will play a part.” Locating these variants will also allow us to better study the interplay between nature and nurture, as the environment is certainly responsible — to some extent — for differences in the way people experience happiness.”These findings, which resulted from a collaborative project with the Social Science Genetic Association Consortium, are available for follow-up research. This will create an increasingly clearer picture of what causes differences in happiness. Professor Bartels points out that “The genetic overlap with depressive symptoms that we have found is also a breakthrough. This shows that research into happiness can also offer new insights into the causes of one of the greatest medical challenges of our time: depression.” The research effort headed by professors Bartels and Koellinger is the largest ever study into the genetic variants for happiness. It was successfully completed thanks to the assistance of 181 researchers from 145 scientific institutes, including medical centres in Rotterdam, Groningen, Leiden and Utrecht, and the universities of Rotterdam and Groningen.
