DNA changes in the DRD4 gene often occur in a 48 base pair repeat region, where the number of repeats can range from 2 – 11.

The “wanderlust” DNA test establishes the length of the repeat region within DRD4. It can specify the number of repeats at each copy. Inheriting at least one copy of the 7R+ allele, which includes 7R, 8R, 9R, 10R and 11R, is associated with an increased likelihood to travel, explore, and discover new foods, places and people.
