ABSTRACT
<p><b>OBJECTIVE</b>To investigate whether there is an association between DRD2/ANKK1 Taq IA polymorphism and early infant temperament.</p><p><b>METHODS</b>DRD2/ANKK1 Taq IA polymorphism (rs1800497) was determined using polymerase chain reaction-ligase detection reaction (PCR-LDR) techniques in 149 Chinese Han infants from Changsha City. Their mothers were asked to complete the Early Infant Temperament Questionnaires (EITQ) when the infants were 1 to 4 months old (mean 2.75 months). There were three genotypes found in these infants C/C, T/T and C/T. The subjects were subdivided into T-carrier (CT, TT) and non-T-carrier (CC) groups for statistical analysis.</p><p><b>RESULTS</b>There were no differences in the temperament style distribution between the T-carrier and non-T carrier groups. There were also no statistically significant differences between the two groups in the score of the nine temperament dimensions.</p><p><b>CONCLUSIONS</b>DRD2/ANKK1 Taq IA polymorphism is not associated with early infant temperament.</p>
