dc.description.abstract | This study investigated the relationships between genetic polymorphisms, personality traits, and academic achievement in medical school students. Study subjects were 220 1st-year medical students at Korea University Medical School during two consecutive academic years (2003-2004). Grade-point averages (GPA) during the second semester of the 1st year of the medical school were obtained as a measure of academic achievement. In addition, all participants completed the Temperament and Character Inventory and questionnaires on depression and anxiety. The polymorphisms in exon III of the dopamine D4 receptor (DRD4) were determined using the polymerase chain reaction. Our results revealed that both male and female subjects with a higher GPA may be characterized as having higher persistence and lower novelty seeking traits. In addition, male subjects with high GPA had higher scores in self directedness and female subjects with a higher GPA may be characterized as having higher scores in harm avoidance. Male students with 4-repeat alleles had a significantly lower GPA than male students without 4-repeat alleles.This relationship also remained after controlling for the personality variables, none of which showed a relationship with the polymorphism after Bonferroni correction. For females, however, no associations could be found between GPA and the polymorphism. Thus, the present study demonstrated for the first time a possible influence of the DRD4 48 bp variable number of tandem repeats polymorphism on academic achievement and proved that this was not mediated by performance-associated personality traits. | en |
