The gene identified as DRD4-7R, has been dubbed the “wanderlust gene,” because of its correlation with increased levels of curiosity and restlessness, for the most part.
This gene is associated with the dopamine levels in the brain. Those who carry this gene variant typically share one common theme, a history of traveling.
The term originates from the German words wandern (‘to hike’) and Lust (‘desire’), literally translated as ‘enjoyment of hiking’. Wanderlust may reflect an intense urge for self-development by experiencing the unknown, confronting unforeseen challenges, getting to know unfamiliar cultures, ways of life and behaviors.
The ‘wanderlust gene’ is the gene DRD4-7R and apparently, those with this gene are much more prone to risk-taking and tend to have more of a need to travel or see the world. This gene seems to be present in some people with ADHD and Schizophrenia as well. DRD4 is the gene that codes for the building of the Dopamine 4 receptor. There are several different versions of this gene but the DRD4-7R is one that draws the most attention. this gene is present in somewhere around 20 percent of the population and those with it are more likely to seek experiences that release more dopamine as they are much less sensitive to dopamine than the average person.
