Cognitive Genetics: Dopenergic System and Academic Performance

From: Beaver et al., 2010. “Three dopaminergic polymorphisms are associated with academic achievement in middle and high school”:

“The 7R allele was coded as the risk allele…DRD4 was related to grades in all four subjects at wave 1 and history and science atwave 2. The reasons why these genes had different effects on different subjects at different times are not immediately obvious. The differential genetic effects, however, likely are produced, in part, by the fact that performance in certain academic subjects depends on the use of specific regions of the brain.”

This shouldn’t be two surprising since DRD4-7 is associated with attention seeking and hyperactivity, not exactly traits rewarded in school.

For a discussion of frequency differences in DRD4 alleles across populations, refer to: Harpending and Cochran, 2002. “It’s in our genes.”
